M.G. Siegler
General Partner, GV
Deeply involved in the startup space since 2005, first as a web developer and then as a journalist, M.G. brings a reporter’s sensibility to his roles as an investor and startup advisor. M.G. credits his journalism background with a key quality he looks for today in founders: the ability to communicate well. “It’s an overlooked skill because a good idea doesn’t always translate into a viable product with users and customers. Storytelling – what you’re doing and why it matters – is incredibly important, whether convincing users to download your app, rallying your team behind a launch, or raising your next round of funding.” Before joining GV, M.G. was a founding partner at CrunchFund, an early-stage investment fund. Before that, he reported on the startup world for TechCrunch and VentureBeat. He still writes regularly for his Medium publication, 500ish.
