On May 15, 2013, Twitter CEO Dick Costolo sat down with Foundry Group Managing Director Jason Mendelson at VentureScape, the National Venture Capital Association's annual meeting. The 30+ minute conversation flowed easily between these two Michiganders, offering unique insights into Costolo's journey and philosophies about running one of the most interesting venture-backed companies today. It was one of many presentations that day that defined VentureScape as the go-to VC event of the year.
