Vinod Khosla, Khlosa Ventures

Vinod Khosla
Khosla, a co-founder of Sun Microsystems and longtime partner with Kleiner Perkins, has been big Silicon Valley player for ages. When he peeled off from Kleiner in 2004 to create Khosla Ventures, it was mainly to invest in green tech. But he's switched courses a bit, and has made investments in consumer plays such as Square and Jawbone.

In October, Khosla closed a $1.1 billion fund that's funding half cleantech startups and half Internet/mobile companies. That's a monstrous fund these days, but Khosla—who recently boasted that he's generated close to $1 billion in profits across all his funds--didn't seem to have much trouble.
