I founded CAMentrepreneurs to support business and social entrepreneurship among Cambridge University alumni, current students and others. CAMentrepreneurs is organised with the same architecture that TED uses to support TEDx-es.
When someone wants to launch a CAMentrepreneurs group in their city, I support them in a similar way to the way that TED supporters TEDx-ers. It’s ultra-low-cost, and therefore sustainable.
