Biography

I am Professor of Management at Hamburg University of Technology (TUHH) and Head of the TUHH Institute of Entrepreneurship (TIE). My research on entrepreneurship and innovation lies at the intersection of organizational theory, sociology, and strategy. I study how actors shape and are shaped by their social, cultural, and technological environments as they create novelty in ideas, teams, products, practices, and business models.

Empirically, I focus on settings in which market, technological, social, or cultural spaces can be observed and measured systematically, including startup innovation, academic science, creative industries, and user communities. I deeply enjoy generating insights from novel data using computational social science and quantitative methods, including econometrics, network analysis, and natural language processing.

In teaching, I bring together rigorous scientific thinking and entrepreneurial practice. Drawing on experiences from universities with strong entrepreneurial cultures, I engage students in hands-on startup engineering and support them in developing and validating their own venture ideas through evidence-based experimentation. I also collaborate regularly with startups and established firms on business model innovation and data analytics.

Venture Capital (VC) investments positively impact startup success, enhancing operational performance through factors like collaboration and value-added services. While research on investment decisions primarily focuses on investors’ selection criteria and decision-making processes, our study addresses the gap in founders’ perspective. Using Generative Pre-Trained Transformers (GPT) for text classification on a dataset of 8,561 online VC reviews, we extract 9,229 unique value-criteria from founders’ perspectives. A text-embedding cluster method categorizes these criteria into 26 categories. By analyzing additional startup lifecycle data, we determine which value-criteria are crucial at different startup stages. Our findings reveal that investors’ “general social skills” are the most important value-criteria across all startup stages, while more mature startups prioritize more self-serving criteria focused on growth and long-term relationships. Additionally, we observe that founders mostly fulfill the value-criteria by investors, with “general advice” being particularly well-executed.

Given that mass media can confer organizational legitimacy and act as an information intermediary between startups and relevant stakeholders, we examine the process of establishing legitimacy and the response to failure across different cultural settings. Employing state-of-the-art natural language processing models, we extract sentiments from a sample of 2,041,607 sentences covering 67,306 startups from the United States, the United Kingdom, and Germany. Utilizing robust econometric methods, we reveal pronounced cultural differences in the character of media coverage for both operating and closed startups. Specifically, German media tends to portray domestic startups less positively, while the United States exhibits the most positive coverage, with the United Kingdom falling in between. Notably, our findings include a positive in-group bias solely for operating startups in the United States, while Germany displays a negative in-group bias for both operating and closed startups. Our study underscores the role of national culture, the importance of comparative entrepreneurship research, and the heterogeneous nature of entrepreneurial phenomena among different cultures.

Journal Article

Scholars have suggested that autonomy can lead to better entrepreneurial team performance. Yet, there are different types of autonomy, and they come at a cost. We shed light on whether two fundamental organizational design choices—granting teams autonomy to (1) choose project ideas to work on and (2) choose team members to work with—affect performance. We run a field experiment involving 939 students in a lean startup entrepreneurship course over 11 weeks. The aim is to disentangle the separate and joint effects of granting autonomy over choosing teams and choosing ideas compared with a baseline treatment with preassigned ideas and team members. We find that teams with autonomy over choosing either ideas or team members outperform teams in the baseline treatment as measured by pitch deck performance. The effect of choosing ideas is significantly stronger than the effect of choosing teams. However, the performance gains vanish for teams that are granted full autonomy over choosing both ideas and teams. This suggests the two forms of autonomy are substitutes. Causal mediation analysis reveals that the main effects of choosing ideas or teams can be partly explained by a better match of ideas with team members’ interests and prior network contacts among team members, respectively. Although homophily and lack of team diversity cannot explain the performance drop among teams with full autonomy, our results suggest that self-selected teams fall prey to overconfidence and complacency too early to fully exploit the potential of their chosen idea. We discuss the implications of these findings for research on organizational design, autonomy, and innovation.

Entrepreneurs face the challenge of having to conform to gain legitimacy, while at the same time differentiating themselves to gain competitive advantage. We show how entrepreneurs can craft an entrepreneurial narrative to succeed in this task among the user audiences empowered to evaluate their products.

Grace, gold, or glory? Exploring incentives for invention disclosure in the university context The Journal of Technology Transfer, 43(6), 1725-1759 2018 Journal Article Thomas Walter, Christoph Ihl, Rene Mauer, Malte Brettel

What motivates university scientists to identify practical applications for their research results and consider having them patent-protected? A wealth of research points towards a complex blend of factors, including organizational antecedents, social norms and personal-level expectations. Few studies, however, have attempted to investigate the effect of concrete incentives from the perspective of individual scientists’ decision-making. In this paper, we operationalize the propensity to patent and commercialize research results as the intention to submit an invention disclosure filing. We use scenario-based conjoint analysis to capture university scientists’ preference structures for different incentive policies. Results indicate that direct and indirect financial incentives are dominant drivers. In addition, a grace period that would allow for patenting and publishing in parallel and the inclusion of patents in academic performance assessments are worth considering, whereas the specific setup of the technology transfer organization and public recognition of achievements in form of an award appear to have limited effect. However, preferences for incentives and hence their effectiveness vary significantly across academic disciplines and ranks as well as with scientists’ working experience, patenting experience and research orientation.
