Since the dawn of Web 1.0 Marc Andreessen has been one of Silicon Valley's heavy hitters, and now he's behind some of the most innovative companies defining the web's future.
He's on the board of Facebook, he invested in Twitter, earlier this year his fund invested in FourSquare, and now he's backing a new social search engine called RockMelt.
Andreessen last week closed a $650 million fund at "Andreessen Horowitz," the VC firm at which he's a partner so today in an interview on CNBC, I asked him how he's going to put that money to work.
First and foremost Andreessen is interested in investing in entrepreneurs. He's open to any variety of Silicon Valley computer science company, which includes social networking, commerce, software and storage. He tells us he's particularly excited about the huge potential in social, but he decides which companies to invest in, based on the entrepreneurs.
