Andreessen Horowitz Finally Adds a Third General Partner, Scott Weiss

The firm is keeping the name, but Andreessen Horowitz is officially no longer just the Ben and Marc show. It has finally added a third general partner, and astoundingly, he didn't come from Opsware . The new dealmaker is Scott Weiss, an experienced entrepreneur who may not be a household name, but like Ben Horowitz and Marc Andreessen has serious entrepreneurial chops, having built consumer and enterprise companies to large scale. The most recent was IronPort, the often forgotten PayPal mafia hit that Weiss co-founded with Scott Banister, selling the company to Cisco for $850 million. Before IronPort, Weiss was employee number 13 at Hotmail. Some people may view the choice as a strange one, given Weiss's absence from the current Web 2.0 frenzy. Then again, not too many years ago some of the press considered Andreessen and Horowitz has-beens of the bubble era.
