Scott Kupor, managing partner at Andreessen Horowitz, says there's a lot about navigating the venture capital world that entrepreneurs don't understand. Some can't figure out how to get in the door. Others fail to deliver persuasive pitches. Many don't know how the deals and relationships really work. Kupor outlines what he and his partners look for in founding teams and business ideas and explains how start-ups work with VCs to become successful companies. He also discusses how Silicon Valley can do a better job of finding more diverse talent and funding new types of ventures. Kupor is the author of the book "Secrets of Sand Hill Road: Venture Capital and How to Get It."
