This paper aims to investigate success factors of innovative start-up firms from the perspective of young start-up managers. Which key factors did they experience before and since the foundation of their company? The experience from the quite young Swiss start-up scene provides important insights to entrepreneurs and policy-makers in emerging countries that currently face the necessity of building up a start-up environment. One part of the data has been collected by the author, the other part originates from the Swiss Venture Capital Database (total sample size: 306). The results show a significant role of venture capital financing for the success of innovative start-ups. Interestingly, this is to some extent because the start-ups see various additional benefits from venture capitalists involved in their firm. Thus, the findings shed new light on a proper definition of venture capital that should not solely focus on the flow of funds. | Innovative start-ups and young entrepreneurs: Definition of venture capital and findings from Switzerland
