Business Model Innovation Through the Lens of Time: An Empirical Study of Performance Implications Across Venture Life Cycles

Current literature suggests that the innovation of a business model is among the most important success factors for organizations and has a positive influence on their performance. What is not yet clear, however, is how this relationship unfolds during an organization’s life cycle. We posit that business model innovation strongly contributes to firm performance in earlier phases, but ultimately gets less important. We therefore collected data on 250 organizations in Germany and used structural equation modeling for analytical purposes. We make the following two main contributions to the literature: (1) We confirm recent findings about the positive impact of business model innovation on performance; (2) we provide first empirical evidence for the important role of life cycle stages as moderator with regard to this relationship. With respect to the latter, our findings show that business model innovation is an important pathway of organizations, especially in their early years of existence, yet somewhat diminishing over time. In conclusion, this study opens new research avenues by extending and incorporating explanations for the life cycle theory and business model innovation.

were able to describe this widely-stated association but mainly in a correlational way and without considering the dimension of time Saebi 2017, 2018). Yet, almost twenty years after the advent of business model research, it is still not clear, whether BMI is beneficial to the firm at all Saebi 2017, 2018). What we know so far is largely based upon empirical studies that investigate how different business model designs contribute to performance effects (e.g., Wei et al. 2014;Amit 2007, 2008). Current studies have shown that environmental factors, e.g., environmental dynamism (Pati et al. 2018), environmental turbulence (Schrauder et al. 2018), and environmental resource munificence (Zott and Amit 2007) influence the relationship. Yet, besides a handful studies, effect-side BMI research has failed to examine contextual factors, such as firm age, firm size, firm characteristics as well as a firm's focal value proposition. First empirical studies acknowledge that performance implications differ across firms in their early or late life cycle stages in case of a more efficiency-centered business model design (Brettel et al. 2012), a paucity of studies, however, remains investigating the impact of the innovativeness of the business model on performance implications for new ventures and more established firms. In a similar vein, research has so far lacked to account for different firm-types, i.e., product-or service-oriented firms, and how their engagement in BMI and the resulting performance implications varies for new and more mature ventures.
In order to improve our understanding, this paper explores the prominent relationship between BMI and firm performance by (1) providing a systematic literature review of empirical studies investigating this relationship, (2) presenting further empirical evidence on the beneficial character of BMI, (3) examining the moderating influence of early and late life cycle stages, and (4) comparing the findings for product-and service-oriented BMIs. We therefore collected data on 250 new and more mature ventures in Germany and used structural equation modeling for analytical purposes. We make the following two main contributions to the literature: (1) we add further evidence to the body of knowledge of effect-side research of BMI, and (2) we bring new contingency factors into the discussion. The paper first gives a systematic literature review, followed by hypotheses derivation. The next section emphasizes the study's research design and methodology, afterwards we present our results. The last section draws these findings together, discusses its implications for theory, as well as for practice, and concludes with limitations and avenues for further research.

Systematic Literature Review of the Effect-side of BMI Research
In order to grasp the amount of current knowledge on the relationship between BMI and firm performance, we conducted a systematic literature review using the procedure suggested by Denyer and Tranfield (2009). By executing a systematic search in three scientific databases, namely in EBSCO Business Source Complete, Elsevier-Science Direct, and Scopus, we not only focused on the search term "business model innovation", but also included the expression(s) "business model design", "business K model development", "business model renewal" or "business model change" which are used interchangeably for the same phenomenon . The search terms had to be included either in the title, the abstract, or in the keywords of peer-reviewed articles between 2000 and December 2020 and by that we identified 1676 articles after removing duplicates. In a next step, we applied an objective criterion (Denyer and Tranfield 2009) to assess the relevance of each study. More specifically, we excluded articles which were not ranked A+, A, or B in the VHB-JOURQUAL 1 ranking to ensure quality as well as theory-focused work. However, we included all articles from the Journal of Business Models, a journal devoted to establishing the discipline of business models as a separately recognized core discipline to get a thorough picture of the literature. This resulted in a total of 397 articles. Furthermore, we reviewed and coded the remaining articles using the MAXQDA software and eliminated publications without a primary focus on BMI; 260 articles were eventually deemed as a fit for our research purpose. We again reviewed and assigned these articles into the categories of antecedents, process, construct, and effects. We found a large volume of published studies describing the role of organizational and individual antecedents (n = 85), research investigating the act of designing and implementing BMIs (n = 75), and investigations into the construct itself (n = 75). However, only a small proportion of studies has devoted its attention to the effect-side of BMI (n = 40), yet with a certain increase in recent years (for an overview see Table 1).
What we know about BMI performance relationship is largely based upon four types of empirical studies that investigate how BMI impacts performance. The first type encompasses the activity system view (Zott and Amit 2010) and investigates how different design themes (Zott and Amit 2007) impact performance variables such as firm performance (Brettel et al. 2012;Wei et al. 2017), technological innovation performance (Hu 2014), start-up's growth performance (Balboni et al. 2019), or small and medium-sized enterprise (SME) performance (Pati et al. 2018). Another stream of effect-side research, the element-based view (Clauss et al. 2019b) connects the innovativeness of the business model with different outcomes, such as strategic flexibility (Spieth and Schneider 2016), internal corporate venturing performance (Futterer et al. 2018), and again firm performance (Clauss et al. 2019a). A third type of studies examines the effects of different aspects that come along with BMI, such as different types of revenue models (Konya-Baumbach et al. 2019), productand service-orientation (Visnjic et al. 2016), or technology and consumer orientation in BMIs (Guo et al. 2020), as well as business model adoption (Karimi and Walter 2016) and business model imitation behavior (Frankenberger and Stam 2020). While these study entail an inside-firm perspective, the fourth type and more recent research shift to a customer-oriented view and examine the effects of BMI on customer satisfaction (Clauss et al. 2019b), adoption intention (Futterer et al. 2020), and brand loyalty (Spieth et al. 2019).
With respect to potential benefits, these studies point to the fact that BMI is a powerful predictor for firm performance (Cucculelli and Bettinelli 2015;Karimi and Walter 2016;Visnjic et al. 2016). However, many questions remain in this young field of study. First, while the majority of the studies connects different business model designs with firm performance, more research is needed examining the impact of the innovativeness of business models within the element-based view.
There are relatively few current studies that indeed present first evidence for the beneficial character but replicating these studies in different contexts might shed new light on the most prominent statement in the BMI literature. Second, while few studies have integrated contingency and moderating variables in their research, there are many factors that may influence the strength of that effect. Current studies have shown that environmental factors, e.g., environmental dynamism (Pati et al. 2018), environmental turbulence (Schrauder et al. 2018), and environmental resource munificence (Zott and Amit 2007), influence the relationship. Yet, besides a handful studies, effect-side BMI research has failed to examine contextual factors, such as firm age, firm size, firm characteristics as well as a firm focal value proposition. Yet, in combination with an element-based approach, the exploration of contextual factors holds the potential to deepen our understanding of the BMI performance relationship. Previous studies have indicated that BMI performance relationship is especially contingent on the factor time (Balboni et al. 2019;Foss and Saebi 2017;Pati et al. 2018), but a clear understanding of the impact on the effect strength is still missing. In the following, we will first discuss the core assumptions of BMI research and subsequently develop an understanding on how different life cycle stages affect this relationship and discuss how this relationship might further vary for productand service-oriented BMIs.

Business Model and Business Model Innovation
For a long time, business models have mainly been used as a template or narrative device to understand and communicate a firm's current activities by managers (Massa et al. 2017). In 2003, Mitchell and Coles moved the idea of managers having the ability to purposefully change a business model into the spotlight . By adding the additional dimension of innovation , business models have eventually become a potential unit of innovation that "complements the traditional subjects of process, product, and organizational innovation" (Zott et al. 2011(Zott et al. , p. 1032. A business model is a formal conceptual representation of a company (Massa et al. 2017) and thereby reflects the "design or architecture of the value creation, delivery, and capture mechanisms" of a firm (Teece 2010, p. 172). In terms of conceptualization, two dominant views have emerged (Clauss et al. 2019b): the activity system perspective (Casadesus-Masanell and Ricart 2010; Zott and Amit 2010) views business models as holistic systemic structures that encompass all activities of a company as well as how and when these activities are carried out (Zott and Amit 2010); the element-based perspective approaches the business model construct as a modular set of elements consisting of three (Bocken et al. 2013;Clauss 2017;Spieth and Schneider 2016) or of four elements (Baden-Fuller and Haefliger 2013;Futterer et al. 2018;Johnson et al. 2008;Osterwalder et al. 2010). This under-standing is rooted in the dynamic perspective on business models (e.g., Casadesus-Masanell and Ricart 2010;Demil and Lecocq 2010;Martins et al. 2015), which refers to dynamic interactions among various business model elements (Casadesus-Masanell and Ricart 2010;Demil and Lecocq 2010). In the following, we will draw on latter one as the element-based view is generally considered as the cornerstone for BMI research (Clauss 2017;Futterer et al. 2018;Spieth and Schneider 2016). According to the element-based view, business models consists of four interrelated elements, namely (1) value offering, (2) internal value creation, (3) external value creation, and (4) financial architecture (Futterer et al. 2018) that capture a firm's foundational processes Saebi 2017, 2018;Saebi et al. 2017). The first element, which reflects the value offering of a company, comprises the products and services offered to the target market (Demil and Lecocq 2010;Yunus et al. 2010), the internal value creation element integrates the methods, processes, structures, and competencies within the company's value chain (Demil and Lecocq 2010;Dubosson-Torbay et al. 2002;Osterwalder et al. 2005), the third element-the external value creation-describes the relationships with external partners, stakeholders, and distribution channels (Kindström 2010;Yunus et al. 2010) and the financial architecture element constitutes the company's revenue mechanisms and cost structure (Chesbrough 2007;Osterwalder et al. 2005;Yunus et al. 2010).
BMI itself is a transformation process that purposely alters the key elements of a business model (Bucherer et al. 2012;Clauss et al. 2019a;Tucci and Massa 2013) and nontrivial changes to these key elements of a firm's business model eventually result in a BMI . Firms can either innovate single elements or introduce a whole new business model . While changing "of at least one core element is the necessary condition for BMI to be given, the sufficient condition is represented by a subsequent change of the BM's underlying logic" (Futterer et al. 2018, p. 2). Since even the change of one core element induces (minor) changes in other elements as well (Demil and Lecocq 2010;Johnson et al. 2008), innovating only one element often requires reconfigurations of the business logic and thus may constitute BMI . In case of established firms, BMI is deemed either the change of an established business model (Amit and Zott 2012;Zott and Amit 2013) or the creation of a new innovative business model that is added to their portfolio (Snihur and Tarzijan 2018). For new ventures, BMI is typically the creation of a new innovative business model Saebi 2018, 2017). Eventually, the reference point for the innovation is either its newness to the firm or its newness to the industry .

Business Model Innovation and Firm Performance
Innovation means "doing something new", e.g., developing new products, new processes, new markets (Schumpeter 1934), and now new business models (Taran et al. 2015). In new product contexts, innovation is considered as the extent a new product differs from already existing ones (e.g., Cillo et al. 2010;Cooper and Kleinschmidt 1987;Danneels and Kleinschmidtb 2001), meaning innovativeness is the difference between old and new (Garcia and Calantone 2002). More precisely, innovativeness covers the amount of newness relative to a certain base, such as the world, the industry, the firm, or the perception of the customer (Calantone et al. 2006;Garcia and Calantone 2002). In case of business models, innovativeness captures the relative amount of newness to the focal firm (e.g., Osterwalder et al. 2005;Spieth and Schneider 2016) or to the industry (Amit and Zott 2012; Snihur and Tarzijan 2018) depending on the perspective. Hence, following the interpretation that business models are attributes of real firms, being innovative in doing business means executing value-adding activities such as value creation and/or value capture (Massa et al. 2017) in the core elements of a business model, namely value offering, internal value creation, external value creation, and financial architecture.
According to Lepak et al. "value creation depends on the relative amount of value that is subjectively realized by a target user (or buyer) who is the focus of value creation-whether individual, organization, or society-and that this subjective value realization must at least translate into the user's willingness to exchange a monetary amount for the value received" (Lepak et al. 2007, p. 182). The value creation is typically described in the most integral part of a business model in the value offering element that comprises the products and services offered to the target market (Futterer et al. 2018). Such changes optimize the resources and competencies employed more toward customers' preferences and are more tailored toward customers' needs, enhancing customer satisfaction (Futterer et al. 2020). By innovating the value creation in a way that it delivers greater value to the target market a company is able to outperform its competitors Ramirez 1994, 1993;Porter 1985). Furthermore, business models also describe the value capture domain: "value may be captured by the use of resources with attributes that make them difficult to imitate, through the source's own use of creative destruction before competitors can use the innovation, and through methods of resource management" (Lepak et al. 2007, p. 189). Value creation in business models is reflected in the internal value chain, relationships with external partners, and the financial architecture of a company; i.e., all activities necessary to monetize the value created (Massa et al. 2017). Hence, being more innovative in the respective business models elements, leads to cost reduction, process optimization, accessing new markets, and eventually to financial performance improvements . This indicates a positive link between business model innovativeness and financial performance improvements. Therefore, we assume the following-H1: BMI has a positive effect on firm performance.

Business Model Innovation and Life Cycle Stages
While prior research often emphasizes BMI as the holy grail for achieving firm performance, more recent research indicates that innovated business models are not always necessarily better than existing business models, such that positive performance implications often strongly depend on contingency factors (Casadesus-Masanell and Ricart 2010; Futterer et al. 2020;Kranich and Wald 2018). Under-standing the contingency mechanisms that unfold BMI into positive firm performance implications is of utmost importance for many firms. Yet, effect-side BMI research neglected to thoroughly discuss contingency factors of this valuable relationship. So far, recent research acknowledges that the performance implications of firms might differ across early and late life cycle stages depending on the business model design, i.e., either novelty-or efficiency-based, they have chosen (Brettel et al. 2012). Yet a more in-depth understanding is still missing. Both, young ventures and more established firms possess a unique bundle of resources and capabilities depending on their individual life stage that provide benefits and weaknesses (Carr et al. 2010). These benefits and weaknesses have an influence on the ventures capability to create and capture value from its BMI (Pati et al. 2018). Organizations grow in a predictable pattern (Hanks et al. 1993) and move through different life cycle stages (e.g., Gaibraith 1982;Kazanjian 1988;Laudien and Daxböck 2017;Quinn and Cameron 1983;Smith et al. 1985). Every venture's life begins with a startup or birth stage, moves through certain growth stages, and ends with a form of maturity or with the decline of an organization (Hanks et al. 1993). Due to conceptual vagueness and a lack of distinctness concerning the individual stages (Hanks et al. 1993), scholars typically differentiate the early and late life cycle stages of ventures (e.g., Brettel et al. 2012;Dodge et al. 1994;Engelen et al. 2010). More established firms have typically gained some form of stability and execute a viable and working business model. These firms typically capture more value from their experiences, well-functioning processes, established routines and longterm partnerships (Kotha et al. 2011). In case of more established SMEs-or firms in their later life cycle stages-BMI means either the change of an existing business model (Amit and Zott 2012;Zott and Amit 2013) or the creation of a new innovative business model that is added to its portfolio (Snihur and Tarzijan 2018). This may happen due to several reasons, e.g., new entrants in the market (Dewald and Bowen 2010), disrupting power of new technologies (Sabatier et al. 2012) or a general emphasis on innovation in a company (Sorescu et al. 2011). Firms in their later life cycle stages have already gained a good sense of their environment, such as their market, customers, and partners (Zahra and George 2002). However, changing an existing business model, like Xerox did when switching from selling copiers to leasing them (Chesbrough and Rosenbloom 2002), comes also with idiosyncratic challenges for the innovating firm, such as path dependencies, organizational inertia, new management processes, and types of organizational learning (Tucci and Massa 2013). The performance effects realized through a BMI might get mitigated by the transition process the company undergoes.
In contrast, new ventures, or firms in their early life cycles stages, are typically created to pursue unexploited opportunities (Dahlqvist and Wiklund 2012), are characterized by smaller firm size, lower age, a more uncertain environment and a different structure (Brettel et al. 2012), and have to take on a long journey before overcoming their liability of newness (Stinchcombe 1965). In new ventures, business models are an important device to narrow down the initial entrepreneurial idea into a describable opportunity (George and Bock 2011). In case of new ventures, BMI means the deployment of an innovative business model right from their inception . The reference point for innovation in this case is the industry. Uber, for example, outperformed established taxi companies, that offered the traditional licensing system, by providing a location-based app and a taxi service via private drivers (de Jong and van Dijk 2015). By being more innovative with their business models than their competitors, they are doing better in creating and capturing value, which ultimately leads to greater firm performance. We argue that this effect is stronger for young ventures in their early life stages for several reasons. First, new ventures tend to have a stronger business sense with less complex decision-making mechanisms, less inefficiencies in their processes, and less rigid structures (Thornhill and Amit 2003). Furthermore, younger ventures deploy an atmosphere of creativity and have clearer information channels (Zaheer and Bell 2005). New ventures have not yet built formalized processes and standardized work procedures (Engelen et al. 2010), since they have to constantly adapt to new and unknown situations (Roure and Keeley 1990). These characteristics of ventures in their early years of existence suggest that they are in a more favorable position to benefit from innovation-related opportunities (Rosenbusch et al. 2011), BMI being one of them. While many new business models fail, before a new one becomes viable, these new ventures with their innovative business models are sources of abnormal returns (Tucci and Massa 2013).
Hence, we conclude that early stage firms might create and capture greater value from BMI and transform it into performance.
Therefore, we assume the following-

H2:
In early stages, BMI has stronger effects on firm performance than in later stages.

Business Model Innovation and Product-and Service-oriented Firm Types
Previous studies have already identified that BMI has a different impact on performance implications, depending on whether BMIs are product-or service-oriented (e.g., Visnjic et al. 2016;Visnjic Kastalli et al. 2013). However, previous studies have not yet determined how these effects unfold in early and late stages of a venture's life. Service-oriented firms are characterized by intangible products and focus on a more people-oriented business (Masurel and Van Montfort 2006). In their early life cycle stages their diversification of object types, clients, and activities is typically rather small (Masurel and Van Montfort 2006) and it is crucially important to implement and market their innovative business model. In the later stages, serviceoriented firms have typically gained broader diversification, more stable relationships with their customers, and deal with a larger variety of markets, clients, as well as sectors (Masurel and Van Montfort 2006). Hence, BMI becomes less important for service-oriented firms, due to other value drivers with greater impact in later stages. In contrast to service-oriented firms, ventures with a greater focus on more tangible assets engage more in product innovation, which is considered as one of the main drivers of value creation (Visnjic et al. 2016). However, sole product innovation is deemed less profitable than product innovation embedded in the appropriate business model (Chesbrough and Rosenbloom 2002;Teece 2010). Product-oriented firms in their early stages normally focus on prototyping, thereby enhancing the design of products and establishing a first production process (Gaibraith 1982). However, the main introduction of the product into a market happens at a later stage of the life cycle where the venture is more mature and established (Lumpkin and Dess 1995).
Therefore, we assume the following-

H3:
The relationship between BMI and firm performance in early and late life cycle stages differs for product-and service-oriented firm types, namely H3a: In case of product-oriented ventures, the performance effect of BMI is significantly higher in later than in earlier stages H3b: In case of service-oriented ventures, the performance effect of BMI is significantly higher in earlier than in the later stages The proposed research model is depicted in Fig. 1.

Data and Sample
In order to answer our research question, we collected data from ventures in German-speaking countries via a cross-sectional research design. With this research design we respond to a former call of Foss and Saebi (2017) who have suggested "to collect cross-sectional data on business model changes and regress those data against business or corporate performance" (p. 212). Cross-sectional designs have been proven to be a valid approach when investigating the link between BMI and venture performance (e.g., Futterer et al. 2020). Yet, cross-sectional designs always have some limitations with regard to establishing causality. In order to alleviate confounding effects surrounding causality that may arise due to a delay of BMI effects on performance outcomes, we assessed the independent variable of BMI at the time of business formation, and the respective dependent variable "firm performance" at the time of the survey. Our sample needs to consist of the key decision makers within their respective ventures, which are considered to be the top management team or the founder(s) of the venture. This is necessary since the key decision makers are those who shape a firm's strategic orientation (Talke et al. 2011) and, hence, the business model. We, therefore, invited entrepreneurs from the most prominent entrepreneurship directories in Germany (e.g., Bundesverband Deutsche Startups, Gründerszene.de, deutsche-startups.de), Switzerland, Austria, and Lichtenstein (Angellist) to participate in our study in 2017. We collected data via a self-administered survey in the months from April to June, including the first approach and one reminder email. We sent an Email to 3884 individual entrepreneurs containing the link to our online-survey or, when no direct contact information was available, to the venture's e-mail address and included the information that had to be forwarded to the key decision maker. We advised the respondents to think about their focal venture when answering the question-bearing in mind that entrepreneurs might have more than one venture. Thereby, 268 questionnaires were returned to us. In sum, eighteen returned questionnaires had significant missing values and straightliners that we deleted, thereby resulting in 250 respondents and an overall response rate of 6.9%. On average, the 250 ventures were founded in 2014 (3 years old) and conducted mostly business in the IT or service industry, which we assessed by the NACE (Nomenclature statistique des activités économiques dans la Communauté européenne) scale. NACE is a four-digit classification of economic activities in the European Community and the participants were asked to self-categorize their venture. Since the service industry has proven to be an adequate research context for studies in the BMI context (Laudien and Pesch 2019), we also consider our sample as appropriate for our investigation. 61.60% of all ventures had less than 5 employees, 19.60% had 6-10 employees, 9.60% had 11-15 employees and 9.20% had more than 16 employees. The average founder in our study is thirty-four years old, male (84%), obtained a university degree, has about 5 years of start-up experience, funded about 2.40 prior start-ups of which 0.55 failed. Concerns about survival bias are mitigated by the fact that every company can be listed in the public entrepreneurship database. Consequently, immature and young companies are also included. Table 2 presents descriptive statistics and zero-order correlations among all variables used in the analyses.

Variables and Method
We drew on established measures (see the Appendix for the main constructs and items) and applied seven-point Likert-type scales except where otherwise stated. We also pre-tested the questionnaire with a group of twelve experts, namely PhD researchers working in the economics department at university, thereby ensuring face validity and clarity (Churchill 1979).

Business model innovation Business Model
Innovation is operationalized as a molar third-order hierarchical construct adapted from Futterer et al. (2018) with four formative second-order elements (Chin 2010): (1) value offering, (2) internal value creation, (3) external value creation, and (4) financial architecture, enclosing thirty-two items that Futterer et al. (2018) derived from established scales. The first element, value offering architecture, builds on the following scales: the noveltycentered business model design by Amit (2007, 2008), product superiority to the customer by Lee and Colarelli O'Connor (2003), and market newness by Dahlqvist and Wiklund (2012). The items for the second element, internal value creation architecture, are adapted from Gatignon et al. (2002), whereas the third item, external value creation architecture, was operationalized with items adapted by the market newness scales of Lee and Colarelli O'Connor (2003), as well as supplier involvement of Chen and Paulraj (2004). Finally, the fourth element, financial architecture, mainly builds on items adapted by Spieth and Schneider (2016), and supplemented by items from Chesbrough (2007), Dubosson-Torbay et al. (2002), as well as Yunus et al. (2010). We asked the founders to think about the moment of the foundation of the company and indicate how innovative their business model was. All items were measured according to a seven-point Likert scale anchored by "strongly disagree" and "strongly agree."

Firm Performance
In general, new ventures do not need to publicize their financial data in financial reports ) and surveying the key informants of the new ventures is a common approach (Anderson and Eshima 2013; Kraus et al. 2012). In accordance with this, we assessed firm performance via the respondents' subjective assessments; they were taken from a synthesis used by Vorhies and Morgan (2005) and comprise previous measures regarding their customer satisfaction (Fornell et al. 1996), profitability (Morgan et al. 2002), and market effectiveness (Vorhies and Morgan 2003) and are commonly used in effect-side research of BMI (e.g., Balboni et al. 2019;Nunes and Do Val Pereira 2020). In studies that are based on the key-informant approach due to the absence of mandatory financial reports this scale entails all components a key informant, such as the founder of the venture, is able to assess. All scales were designed as seven-point scales and we estimated overall firm performance as a reflective second-order construct, comprising the three first-order latent performance factors, thereby building a type I hierarchical component model (Hair et al. 2018).

Organizational Life Cycle Stage
The moderating variable in our research model, organizational life cycle stage, was operationalized by using the scale of Brettel et al. (2012) who adapted a five-stage classification scheme from Lumpkin and Dess (1995). In accordance with this, we followed the approach of Brettel et al. (2012) and provided an explanatory sentence for each stage. The five stages included (1) startup/conception and development, (2) commercialization/market entry, (3) growth, (4) consolidation, and (5) maturity/diversification. Similar to Brettel et al. (2012), as well as Engelen et al. (2010), we built two groups, namely early and later stages. The first one included the stages (1) startup/conception and development, as well as (2) commercialization/market entry. The latter one incorporated the last three stages (3) growth, (4) consolidation, and (5) maturity/diversification. Table 3 gives an overview of the stage classifications.
K Our company has a product that performs well and meets a need in the marketplace. It has some revenues and some backlog of orders. We have the capability to produce and sell, but we have yet to firmly establish the company in the market Growth Our company is characterized by high growth rates in sales. The major internal focus is around issues of how to produce, sell, and distribute the products in volume Later Stages

Consolidation
Our growth rate slows to a level consistent with market growth. The primary focus of our activities is to attain profitability while maintaining growth momentum

Maturity/ diversification
Within this company, the major internal activities include diversification efforts. We develop second or third generation products or totally new product lines and work on the penetration of new geographic markets

Control Variables
The relationship between BMI and performance depends on several variables for which we included control variables: age, sex, and education of the key respondents as well as firm size measured according to the number of employees. Although all the firms included in our study were relatively young ventures, the firm size might still influence the relationship between BMI and firm performance.

Common Method Bias
In order to control for common method bias, procedural and statistical remedies were combined (Podsakoff et al. 2012). We applied proximal and psychological separation between our independent and dependent variable to reduce the respondents' ability to use a similar response pattern (Podsakoff et al. 2003). Statistical remedies included Harman's single factor test (Podsakoff et al. 2003), the Lindell-Whitney marker variable test (Lindell and Whitney 2001), and Kock's collinearity test (Kock 2015). All the independent and dependent variables were included in an exploratory factor analysis, resulting in a total variance of 35.55%, that is below the common threshold of 50% (Podsakoff et al. 2003). Next, we applied the Lindell-Whitney marker variable test by integrating the measurement inventory of team trust (Bansal et al. 2004) in the model as a theoretically unrelated latent variable (Lindell and Whitney 2001). The highest path coefficient turned out to be 0.15, which is below the common threshold of 0.30. In addition, we applied a full collinearity test and found that all the variance inflation factors (VIFs) of the latent constructs in our model were not higher than 3.30 (Kock 2015). This indicates that common method variance should not be a concern in our model.

Statistical Procedures
We used structural equation modeling (SEM) to test our research model as this statistical technique allows assessing complex models with different relationships simultaneously (Reinartz et al. 2009). More specifically, we applied partial least squares (PLS) SEM that combines indicators to build composite variables (Lohmöller 1989), which are designed to be the proxies for the constructs under investigation (Rigdon 2016). We have chosen PLS-SEM over covariance-based techniques for several reasons. First, since our study focuses on prediction rather than exploration, indeterminacy is less suitable in a covariancebased approach and more suitable in a PLS approach (e.g. Dijkstra 2014). Second and most important, contrary to CB-SEM approaches, PLS-SEM is capable of modeling type IV higher-order constructs (Chin 2010), which are present in our research model. PLS-SEM has recently been applied to entrepreneurship studies (e.g. Radosevic and Yoruk 2013), in BMI research (Futterer et al. 2018), innovation research (Heidenreich et al. 2016), and to other management topics (for an overview, see Hair et al. 2011). For statistical analyses, SmartPLS 3 (Ringle et al. 2015) was used to estimate the inner and outer model parameters by applying a path weighting scheme (Chin 1998). We also employed non-parametric bootstrapping (Chin 1998;Tenenhaus et al. 2005) with 5000 replications and mean replacement as missing valuealgorithm, as well as individual-level change pre-processing, to obtain the standard errors of the estimates. The higher-order latent variable BMI was set up by using the hierarchical component model approach (Lohmöller 1989;Tenenhaus et al. 2005). In order to handle the measurement issues of higher-order models in PLS-SEM, researchers can apply the repeated indicators approach, the two-stage approach, or the hybrid approach (Becker et al. 2012). In a simulation study, Becker et al. (2012) found that the repeated indicators approach provides better results when it comes to parameter estimates and lower-order construct scores than the other two techniques. Only in certain cases, the approach is particularly problematic: For example, when assessing reflective-formative and formative-formative hierarchical component models (HCM) or when the higher-order construct (HOC) has one or more antecedent latent variables (Becker et al. 2012). Similar to our research model, the reflective-formative-formative BMI construct is exogenous and the dependent variable-firm performance-is a reflective-reflective HCM; we draw in both cases on the repeated indicators approach. It assigns all indicators of the lower-order constructs to the measurement model of the HOC (Lohmöller 1989;Wold 1982) and can also be applied to thirdorder HCM (e.g., Wetzels et al. 2009). Nevertheless, additional technical considerations need to be considered. First, the indicators at the lower level should not vary strongly when it comes to their number (Becker et al. 2012); second, the measurement models of the HOCs needs to be evaluated in terms of the relationship with their lower-order components (LOC); third, this necessitates additional attention to the collinearity, significance, and relevance of the relationships between the HOCs and LOCs (Hair et al. 2018). We now proceed to evaluate the structural and the measurement models.
K 5 Results

Evaluation of the Measurement Model
In a first step, we evaluated the hierarchical measurement models of the constructs under investigation, thereby following the criteria and procedure pointed out by Hair et al. (2017). The eight first-order constructs of the molar higher-order construct BMI, as well as the three first-order constructs of the dependent variable firm performance, all have a reflective nature, which means that internal consistency reliability, convergent validity, and discriminant validity need to be evaluated (Hair et al. 2017). In terms of internal consistency and reliability, composite reliability values all exceed the threshold of 0.70 ) and the same applies for the Cronbach's alpha values, which are all above 0.70. When it comes to convergent validity, all the indicator loadings of the reflective constructs are well above the threshold value of 0.70 and further analysis shows that the indicator loadings squared are above 0.50 (Hair et al. 2017). The average variance extracted values are all above the required minimum level of 0.50 (Fornell and Larcker 1981). In terms of discriminant validity, the values of the heterotrait-monotrait ratio of correlations (HTMT)-with the highest one turning out to be 0.862-are also below the threshold of 0.9 (Gold et al. 2001;Teo et al. 2008). As stated above, in terms of HOCs, the measurement models are evaluated according to their relationship with its lower-order components, thereby accounting for the same evaluation criteria and thresholds. Consequently, the HOC firm performance, which is likewise a reflective construct, was assessed and the above stated measurement criteria were all met. However, in reflective-reflective or formative-reflective HCMs conceptual and empirical redundancies are expected and, hence, discriminant validity between HOCs and LOCs is of no relevance (Hair et al. 2018). In a next step, the measurement criteria of the second-level constructs-that is, the four business model elements, as well as the first-level construct BMI itself, which are all operationalized as formative constructs-are assessed in terms of their relationships with their corresponding LOCs. Consequently, the measurements models are evaluated with regards to potential collinearity issues, as well as the significance and relevance of formative indicators (Chin 2010). In terms of collinearity, the VIFs were assessed (Cassel et al. 1999;Diamantopoulos and Winklhofer 2001) and found to be uniformly below the threshold value of 5 (Hair et al. 2013). We, therefore, conclude that collinearity is not an issue in this model. Next we analyzed the outer weights for their significance and relevance by applying a complete bootstrapping procedure using 5000 bootstraps (Hair et al. 2017). In terms of significance levels, we found that all the formative constructs' relationships with their LOCs are significant at a 1% level. All criteria in terms of formative measurement models are therefore met. Appendices 1-4 and Fig. 2 give an overview of the measurement models and their indicators. Considering the results of all the reflective and formative constructs, we found that they exhibit satisfactory levels of quality. Therefore, we could proceed with the evaluation of the structural model.

Evaluation of the Structural Model
The main research goal of this study was to empirically examine the relationship between BMI and firm performance. We, therefore, collected primary data and used SmartPLS 3 (Ringle et al. 2015) to test the hypotheses by examining the path coefficients and significances of the structural model. Fig. 2 illustrates the results of the structural model. Again, we followed the procedure outlined by Hair et al. (2017). With respect to the inner model, no VIF value exceeded the threshold of 5-in fact, the highest value turned out to be 2.441, thereby indicating that multicollinearity should not be a concern. The R-squared value in the structural model for the relationship between BMI and firm performance turned out to be 0.247 with an effect size f 2 of 0.159. The blindfolding procedure resulted in Q-squared values above 0 for all endogenous constructs, thereby indicating predictive relevance. BMI has a positive effect on firm performance (β = 0.336, p < 0.001), thereby confirming Hypothesis 1. Furthermore, the life cycle stage of a firm negatively moderates the positive relationship of BMI with firm performance (β = -0.154, p < 0.01), thereby supporting Hypothesis 2. We also studied the moderating relationship by using a separate interaction analysis. Thereby, we used latent variable scores and standardized the predictors prior to the analysis to account for multicollinearity (Aiken and West 1991). Table 4 and Fig. 3 show the results of the analysis. The two-way interaction of BMI and life cycle stage is significant and negative (β = -0.483, p = 0.019).
In a next step, we tested for differences between product-and service-oriented BMIs and we again conducted two separate interaction analyses, one for productoriented and another for service-oriented firms. The interaction analysis shows that     Table 5 and Fig. 4 indicate, the difference between early and late stages is not statistically significant in product-oriented ventures (β = -0.435, n. s.) and therefore, Hypotheses 3a is not supported. On the contrary, in the case of service-oriented ventures, the performance effect of BMI is significantly higher in the earlier than in the later stages (β = -0.529, p = 0.025), thereby providing support for Hypotheses 3b.

Additional Analysis
In addition to our research framework, we have calculated an additional analysis as we wanted to determine the relative importance of each element of BMI in early and late life cycle stages. It has been noted that the often stated, yet vaguely described relationship between BMI and performance relationship is difficult to study, due to its complexity . This complexity stems from the "multiple complex links" (p. 212) between the business model elements and the performance implications that are not only intertwined, but also unfold differently over time. In addition, previous studies have also identified that elements of BMI have a different impact on performance (Schneider et al. 2013). In order to determine the innovation contribution of each business model element in each life cycle stage, we conducted four separate interaction analyses. Table 6 and Fig. 5 show the empirical results and graphic illustration of how each BMI element takes effect on performance in different life cycle stages. Academic research has, thus far, claimed that BMI is a strong driver of firm performance . However, an important, but largely overlooked research issue is if and to which extent BMI differs in firm performance across different life cycle stages, namely the early and late stages of a venture's life. Hence, this study strives to add to BMI and life cycle theory by making the following con-tributions: (1) Our research confirms recent findings on the positive impact of BMI on firm performance, (2) it provides first empirical evidence about the moderating role of life cycle stages on the relationship between positive BMI and performance, and (3) it investigates for the first time how this relationship differs for product-and service-oriented firms. First, this study found evidence for the hypothesized positive relationship between BMI and firm performance. This finding is in line with previous research in the academic realm (Brettel et al. 2012;Cucculelli and Bettinelli 2015;Futterer et al. 2018;Kim and Min 2015;Zott and Amit 2007). We contribute to current literature by confirming that more innovation in business models will, indeed, result in higher performance .
Second, the life cycle stage's moderation of a venture brings an important factor into the discussion about the performance advantages of BMI. We thereby extend and challenge extant literature on the outcomes of BMI (Cucculelli and Bettinelli 2015;Zott and Amit 2007) by providing-for the first time, to the best of our knowledge-empirical evidence for the impact of BMI on firm performance in early and late life cycle stages. More specifically, the more innovative a business model becomes, the higher are the performance implications for ventures in their earlier stages. In accordance with these results, previous studies have demonstrated that BMI leads to firm performance in the earlier stages of entrepreneurial firms (Brettel et al. 2012;Cucculelli and Bettinelli 2015;Zott and Amit 2007). Perhaps the most striking finding is that in the cases of more established ventures; an increase in BMI does not automatically lead to higher rates of performance. This result has not yet been previously described and extends current research on the outcomes of BMI that assumes a positive relationship . Although anecdotal evidence shows that established companies like Xerox, Gilette, or Apple successfully innovated their business model and were rewarded with higher performance rates than before. Our findings suggests that the performance implications are not tied to the innovativeness of the business model. An explanation for this phenomenon might be that BMI in firms in their later life cycle phases is a positive trigger in the beginning, but that the value creation and capture mechanisms do stem from their existing assets rather from the innovativeness of the BMI itself. In contrast to more established firms, newly founded ventures often operate in niche markets, serve other customers than incumbents, employ novel resources, and are in a situation where they can play actively with their new business models (Tucci and Massa 2013). Further, firms in their early stages are highly centralized in their founder (Chandler and Hanks 1994), who is able to monitor and steer the BMI process. A comparison of these results with those of other studies confirms that companies with a high level of control have a higher innovation-input-output ratio (e.g., Duran et al. 2016). In similar vein, compared to their later stages, new ventures are less formalized and departmentalized in their earlier stages (Hanks et al. 1993) and are, therefore, much more flexible (Jaworski and Kohli 1993). After surviving the liability of newness, the business model of firms in their early stages is the central asset for creating and capturing value, and ultimately to generate performance implications. By providing empirical evidence, we extend the life cycle theory with the phenomenon of BMI and conclude that relying only on the innovativeness of the implemented business model in the later stage of a venture's life, will not enhance organizational performance.
Third, our results deliver first empirical evidence on how the interaction effect of life cycle stages differs in the case of product-and service-oriented firms. We found contradictory results. In the case of service-oriented ventures, a more innovative business model especially pays off in early stages, but performance declines during the later stages like we expected. However, in the case of product-oriented ventures, our results show that BMI is important in both stages with no statistical difference between early and late stages. A possible explanation might be that in the event of market acceptance, a venture's main goal is to establish itself in the market (Abernathy and Utterback 1982;Moore and Tushman 1982) and in later stages, ventures aim to maintain their market position by developing a second generation of their product (Kazanjian 1988;Moore and Tushman 1982). In both cases, an innovative business model designed around their focal products might help leverage their customer adoption. Besides being the first study to investigate how the relationship between BMI and firm performance differs for product-and service-oriented firms, we also extend existing knowledge with regards to the life cycle theory.
Fourth, when it comes to the individual contribution of business model elements in each life cycle, our findings of the additional analysis are mostly in line with the main analysis. More specifically, the innovation of all business model elements pays off more in a venture's early life than in its later stages; this means that ventures in their early stages need to have greater pressure for BMI, ultimately leading to firm performance. However, in the event of value offering, as well as internal and external value creation, the innovation of the elements in later stages leads to smaller performance implications. A possible explanation might be that firms in their later stages have already gained market acceptance of their offering (Kazanjian 1988;Moore and Tushman 1982), they have gained a status of formalization with efficient and implemented processes (Churchill and Lewis 1983;Gaibraith 1982), and they have established stable relationships with their partners and customers (Masurel and Van Montfort 2006). After gaining stability and reducing uncertainty for the first time, a change in these offerings, processes, and relationships might lead to confusion and inefficiencies, and ultimately to decreased performance. However, an innovation of the financial architecture element contributes to venture performance in both stages. This is in accordance with current research. In the BMI domain, prior research has shown that efficiency-centered business models, that is, business models designed to reduce transaction costs, enhance firm performance Amit 2007, 2008), especially in later stages of organizational life (Brettel et al. 2012). By first investigating how business model elements impact on firm performance in different life cycle stages, we extend existing knowledge by adding a more finegrained analysis, which has only been marginally investigated thus far (Schneider and Spieth 2014). Thereby, we laid the groundwork for disentangling the business model construct into its sub-elements with a certain emphasis on the different life cycle stages of ventures.

Managerial Implications
These findings may help managers and entrepreneurs to understand how to leverage a new business model to success. In line with earlier studies (Cucculelli and Bettinelli 2015;Zott and Amit 2007), research has found that BMI is an important predictor of performance implications in organizations. Our findings show that a more innovative business model makes a stronger contribution toward organizational performance than a less innovative one. A key policy priority for managers should, therefore, be to design and implement an innovative business model. Second, our results show that especially in the early stages of an organization's life cycle, an innovative business model entails a unique selling point and is a key asset in a successful growth process. The more a venture grows, the less important an innovative business model becomes as other factors gain in importance. Within this context, this study shows that the individual life cycle stage of an organization has an important impact on the performance outcomes of BMI and should, therefore, be carefully assessed. Third, our results point out that managers of organizations have to take their firm type-either a product-oriented or a service-oriented venture-into account. According to our findings, especially in the earlier stages, a service-oriented venture has, to a certain extent, emphasize the design and development of a rather innovative business model. In later stages, however, a very innovative business model might lead to decreased performance. In case of product-oriented ventures, an innovative business model is highly important in both stages. In sum: We advise managers and entrepreneurs to not only carefully assess the innovativeness of their ventures' business models, as well as its elements, by, for example, using the measurement inventory of Futterer et al. (2018), but to also assess, respectively, each life cycle stage the venture is currently passing through by using the framework of Kazanjian (1988). Furthermore, the venture's main offering, which is either a service or a product, must be taken into account for the best possible organizational performance outcome.

Limitations and Avenues for Future Research
The findings derived from this study make several contributions to the current literature. However, as with any study, this one also has its limitations. First, we conducted a cross-sectional investigation of the relationship between BMI and performance in the new ventures domain to empirically examine the positive implications. Although using cross-sectional data is a common approach in BMI research (Futterer et al. 2018), such approach might suffer from several limitations. The most important one for our investigation might be tied to a potential delay of performance effects of BMI. While we did account for potential confounding effects due to such delay within our measurements, future research might replicate our findings employing a longitudinal sample to completely rule out any confounding effect in this regard by establishing true causality. Second, both the independent and dependent variable were assessed by the same instrument, i.e., survey, and respondent. To minimize potential problems due to common method bias, we applied procedural and statistical measures to rule out common method variance as effectively as possible. However, again replicating our findings by a longitudinal study with secondary data might provide additional support for our results. Furthermore, in terms of the moderating role of a firm's life cycle stage, a longitudinal design might provide additional insights and a more fine-grained analysis of the complex mechanisms of BMI and the growth process of a firm. Third, in similar vein, we split our dataset into two stages of a venture's life, namely early and late stages. Although it has provided initial insights into the moderating role of lifecycle stages on firm performance during BMI, it also comes with a lack of information. We therefore encourage scholars to examine the growth process of a new venture in each stage to link their individual growth pattern with the relationship between BMI and performance. A more fine-grained analysis might shed more light on the prominent relationship and produces viable insights in the underlying mechanism on how performance effects unfold over time. Forth, our study was not able to account for the amount of structural change brought about by the innovation of a business model in an established company. Although we split our dataset into early and late stages, the latter stage does not resemble established companies, since our dataset entails only young and older new ventures, but not established companies. When it comes to directions for future research, further studies might explore the relationship investigated in established companies with a special emphasis on the stages of maturity, diversification, and decline. This might result in worthwhile contributions to research on the life cycle theory and BMI. Fifth, an arguable weakness of this study is the founders' self-evaluation of performance as a dependent variable, which makes these findings less generalizable. Although new ventures do not need to publicize their financial data ) and surveying the key informants of the new ventures is a common approach (Anderson and Eshima 2013;Kraus et al. 2012), future research might work with secondary data, such as the amount of investments a venture receives during its growth process as an indicator for third-party's trust in its potential to validate and strengthen our findings.
