Developed on the basis of a comprehensive literature review and research questions, this work analyzes the success factors of corporate spin-offs, their relative contribution to the process and the role of the different actors involved. The authors propose a broad range of success factors and success dimensions. Using a combination of multivariate models, the responses to a questionnaire from 211 European companies are analyzed and typologies derived. The result is a new and comprehensive perspective on the relative contribution of each success factor, their interaction, and the behavior of both the parent and the spin-off companies in the process.
