Founders Fund raises $107M third fund (SEC filing)

Founders Fund appears to have raised $107.2 million in equity and pooled investment fund interests, according to a filing with the Securities and Exchange Commission. Led by PayPal cofounders Ken Howery and Peter Thiel with Napster founder Sean Parker (pictured at right) — and an early investor in superstar startups Facebook,, and Slide — it has become one of the top firms to watch.

This will be the San Francisco firm’s third fund. It has previously focused on early-stage investments ranging between $500,000 and $5 million. It is also known for its subsidiaries — the seed fund FF Angel and micro-seed fund fbFund. It operates the altter jointly with Accel Partners and Facebook to back startups innovating for the social network (like GroupCard, which was acquired last week).

So far this year, the Founders Fund invested in Plancast parent company Worldly Developments, startup tracker and analytics service YouNoodle and media measurement tool Quantcast.

The firm raised its second fund, amounting to $220 million, in December 2007. The money came from individual contributors, as well as institutional investors. Most of these partners have not been disclosed, although some reports say Stanford University’s endowment chipped in. The firm launched in 2005, with $50 million from private individuals.

We have asked Founders Fund for comment and will update once we hear back.
