5 The next wave of great founders will come from Uber. When asked which U.S.-based company will spin out the next generation of notable founders, 23% of respondents named Uber. Slack (16%), Stripe (15%) and Airbnb (14%) were next in line. We think the next great startup can come from anywhere, so whether you've worked at one of these companies or not, we'd love to be your first call ;-)
