About Sean

Sean Parker is an entrepreneur with a record of launching genre-defining companies that reinvent ways to spread information online. In 1999, at the age of 19, Sean co-founded Napster and changed how people think about and share music. Two years later, Sean co-founded Plaxo, pioneering viral engineering technology for updating contact information. Sean served as Plaxo's president until 2004, when he joined with Mark Zuckerberg to develop the online social network Facebook. Sean was Facebook's founding president, helping transform that small start-up into an industry giant. Sean's latest venture is Causes, which he co-founded in 2007, and which has become the largest online platform for grassroots activism and philanthropy. At Founders Fund, Sean searches for and fosters the same spirit of innovation that he saw at Facebook, Plaxo, and Causes in new company founders, and has provided essential mentorship to the portfolio companies, including helping develop Alamofire's wildly popular PackRat.
