This was a presentation to celebrate 5 years of a Business Angel Club on EPFL Campus. We gathered 25 entrepreneurs and 250 participants on May 22nd in the Rolex Forum building. My theme was “What have we learned from innovators ? “ At EPFL, 2013 was marked by Henry Marckram’s idea of the Human Brain Project HBP, that became a Flagship European project. So the question became : "what goes in the brain of entrepreneurs ?" Are they Could it be that is "left-brained" logical, analytical and objective, or "rightbrained" - intuitive, thoughtful and subjective ? 60 mentors and investors at A3 Angels has been involved since 5 years with 30 entrepreneurs. We looked into their eyes and found 3 core values to inspires ourselves : 1. Trust (left) 2. Seriousness (left) 3. Fun (right) - AND surprising characters !
