Paris-born, Iranian-American Pierre Omidyar is cofounder and current chairman of eBay.
In 1998, he and his wife, Pamela, established the Omidyar Foundation, an organization that now includes Omidyar Network, HopeLab, Humanity United, and Ulupono Initiative. The organization donates to a diverse range of causes, including entrepreneurship, human rights, food and energy, and games and technology. In 2012, Omidyar and his wife joined the Giving Pledge initiative started by Warren Buffett and Bill Gates, promising to donate most of their wealth to charities.
In August 2015, Omidyar reportedly sold 10% of his shares in eBay to undisclosed charities — a stock gift valued at nearly $270 million.
