Sean Parker, aka “one of the Seans of Silicon Valley,” showed up at a Burbank tech company and won some new fans, including myself. Parker who co-founded Napster, Facebook, and Plaxo is also the founder of Facebook Causes and the Managing Partner at the Founders Fund. Sean was sharp, funny, generous and charming. And young. (How could he do all that and be so young?) Visiting his office in Silicon Valley, I also had the pleasure of meeting the Founders Fund gang as well as the charismatic mayor of San Francisco, Gavin Newsom. Special thanks to Hollywood rainmaker Kevin Allyn and rock style icon Nikhil Ra for setting it up.
