Tie Formation in Silicon Valley and Berlin: How Entrepreneurial Ecosystems Impact Interorganizational Tie Formation of Innovative Growth Companies

Networks are highly relevant for innovation as well as for entrepreneurship. Especially newly founded, innovative high-growth companies heavily rely on resources from their environment—foremost the respective entrepreneurial ecosystem—to develop innovative technologies. Although extant research showed the importance of personal and interorganizational networks during innovation and entrepreneurship processes, much less is known about how new ventures actually form these important relationships. Innovative growth companies face particular challenges when forming interorganizational ties. Especially during the early founding stages, they need to form interorganizational ties under conditions of high uncertainty and power asymmetry. My qualitative case study compares interorganizational tie formation of innovative start-ups and university spin-offs in Silicon Valley and Berlin. Based on 85 interviews and observations of 26 entrepreneurship events, I show that personal ties can be used in very different ways to form interorganizational ties in the entrepreneurial ecosystems in Silicon Valley and in Berlin. The importance of personal ties for interorganizational tie formation varies between the two entrepreneurial ecosystems. The strength of personal ties influenced by the institutional environment.
