While it has become widely acknowledged that high potential companies are a vital force in securing innovation and social prosperity, the manifold influence of venture capitalists on these companies has called for the development of a theoretical framework. This study makes a comprehensive enquiry into the nature of venture capitalists' contribution to the development of their portfolio companies and discusses their involvement in managerial processes. Three in-depth case studies on German high potential companies complement the theoretical findings and allow a detailed insight into the reality of venture capital financing. As a result, this book provides valuable knowledge for scholars, entrepreneurs, investors and venture capitalists.
