David Hirsch, 38

Managing partner, Metamorphic Ventures
Formerly director of offline media, strategic accounts at Google

David Hirsch started doing angel investing in 2006, while he was still employed at Google. But investing in companies part-time felt too haphazard to him. He was looking for something more formal and organized. New York's Metamorphic Ventures, which invests in services that help digital media companies convert all those page views into money, proved the answer. Metamorphic is sort of a cross between an investor and an incubator, housing a shared facility for portfolio companies that also share a CFO.
