Meet the Facebook Mafia
Parker first disrupted the business world—and caught the ire of the music industry—in 1999 when he launched Napster. After founding online address book company Plaxo in 2001, he joined Facebook as its inaugural president in 2004. Since leaving the company under questionable circumstances, he formed Founders Fund with investor and former PayPal executive Peter Thiel. Parker also has been enlisted to help woo the music labels he once irritated: He is a Spotify investor and board member. This June, he will reveal his stealth start-up Airtime, which he created with Napster co-founder Shawn Fanning.
