"Corporate venturing has gained much attention due to challenges and changes that occur because of discontinuous innovations - which seem to be promoted by digitalization. In this context, open innovation has become a promising tool for established companies to strengthen their innovation capabilities. While the external opening of the innovation process has gained much attention, the internal opening lacks on investigations. Especially new organizational forms, such as Internal Corporate Accelerators, have not been investigated sufficiently. This study, which is based on 13 interviews from two German tech-companies, contributes to a better understanding of this new form of corporate venturing and the resulting effects on the organizational renewal."
