Ben Horowitz runs influential Silicon Valley venture capital firm Andreessen Horowitz, whose successful bets include Instagram, Oculus VR and GitHub. He cofounded the VC firm in 2009 alongside Marc Andreessen. It now manages more than $100 billion in assets and raised over $15 billion in new funds in January 2026. Horowitz and Andreessen worked together at Netscape, which Andreessen cofounded with fellow billionaire Jim Clark before selling the web browser startup to AOL in 1998 for $4.2 billion. The pair then cofounded data center software company Opsware (formerly Loudcloud), which they sold to HP for $1.6 billion in 2007. Andreessen Horowitz has backed a string of older-generation companies that helped shape the modern internet, including Skype, Lyft, Medium and Okta, among others.
