In 2004, Parker saw a site called "The Facebook" on the computer of his roommate's girlfriend, who was a student at Stanford. Parker had experience in the social networking industry as an early advisor to Friendster and its founder, Jonathan Abrams, for which he was given a small amount of stock in 2003. Parker met with Mark Zuckerberg and Eduardo Saverin, and a few months later joined the five-month-old company as its president. According to Peter Thiel, Facebook's first investor, Sean Parker was the first to see potential in the company to be "really big", and that "if Mark ever had any second thoughts, Sean was the one who cut that off."
