As an active angel investor, Stefan was involved in successes like “Gate5/Nokia Maps” and had to accept disappointments like “Txtr”. As a result, he recognized the importance of corporate culture and, furthermore, his first-hand experience helped countless companies become successful. This included steering his companies through the major global economic crises of 2001 and 2008, successfully repelling enemy takeovers and reinventing them each time. Stefan’s business philosophy is simple: “Passion and culture eat strategy for breakfast.”
