I'm joined by Scott Johnson of Blitzscaling Ventures to discuss OfferUp, the local marketplace company that recently bought its rival LetGo and raised $120 million.  We discuss the history of OfferUp, my own usage of the service as a substitute for hauling goods to the garbage dump, and run through a blitzscalability analysis of the company before congratulating my friend Josh Breinlinger of Jackson Square Ventures, who led the company's Series A round in 2013.
