Jim Goetz, Peter Fenton, Jim Breyer: Top 6 Venture Investors for 2014

No. 2: Marc Andreessen

The entrepreneur turned full-time investor has made a name for himself since he joined forces with Ben Horowitz in 2009. Currently, he sits on the boards of Facebook, Anki, Oculus VR, and Hewlett-Packard Company (NYSE:HPQ). With so much investing and advising on his agenda, one would say that Andreessen is a pretty busy man. Regardless, he somehow finds the time to engage with his more than 80,000 followers on Twitter, where he frequently chats on topics such as media or anonymous sharing mobile apps.
