Auren Hoffman 5

Auren is usually one of the first guys I hit up with startup related questions. He's sold three companies already and is doing really well with his fourth one. He's direct, he's blunt, and he knows his stuff. And if he doesn't know the answer to your question, there is no doubt he can put you in touch with someone who can help - he may have the best personal network of anyone that I've met.
