Before he became a billionaire venture capitalist, Sean Parker blew up the music business by founding the file-sharing service Napster. Now he plans to spend his fortune upending another calcified industry: philanthropy. Parker, 35, told The Chronicle this week that he intends to give away most of his estimated $2.8 billion fortune in his lifetime. He called the Giving Pledge — a public promise made by fellow billionaires like Bill Gates and Warren Buffett to give away at least half their fortunes — “a good starting point.” “But the Giving Pledge is not aggressive enough,” he said. http://www.sfgate.com/business/article/Sean-Parker-plans-to-spend-his-fortune-disrupting-6345186.php
