Lizzie O’Leary talks with Marketplace Tech host Ben Johnson about the future of start-ups. Ben was in San Francisco this week at an annual event called TechCrunch Disrupt. It’s part-Silicon Valley mogul party, part-start-up popularity contest, but it’s also an event where venture capitalists and others get a sense of the future of start-ups … and maybe invest.

Ben and the rest of the Marketplace Tech team will be highlighting what stood out from TechCrunch Disrupt over on their website throughout this week.
