As Company Builders, we at WhatAVenture continuously assess new business models. Based on our experience, we have developed a structured and systematic approach to do so. In order to decide whether to further invest in a new business idea, it is important to understand early on the risks related to the opportunity. In the speech, the focus will be on a hands-on approach to assess the market desirability, technical and regulatory feasibility, economic viability and contextuality of the business idea. This approach provides a 360°-view already at an early stage, crucial to assess the success potential of new business models.
