Billionaire Marc Andreessen, best known as a co-founder of Netscape, the pioneering Web browser, is fast becoming one of the most influential venture capitalists in Silicon Valley. His firm, Andreessen Horowitz has quickly become a powerhouse in Silicon Valley, which for years was dominated by (relatively) old-guard VC firms such as Sequoia Capital and Kleiner Perkins Caulfield and Byers.
Andreessen Horowitz, which now has $2.7 billion under management, has invested in Facebook, Twitter, Groupon, and Instagram, among dozens of other start-ups. The firm recently led a $60 million investment round in fast-growing, San Francisco-based car sharing startup Lyft. In 2012, Andreessen, 41, was named to the TIME 100 list of the most influential people in the world.
