As eBay's first employee and President, Jeffrey Skoll oversaw the company's meteoric rise from Internet start-up to multi-billion-dollar company. While he no longer works for eBay, Skoll maintains a roughly 4% stake. These days he funnels much of his money and energy into his production company, Participant Media, which makes films intended to inspire social change, such as Al Gore's Oscar-winning documentary on climate change, "An Inconvenient Truth." Participant's most recent release, "The Help," grossed more than $200 million in theaters worldwide. Skoll has already given away more than $1 billion, primarily through his Skoll Foundation and Skoll Global Threats Fund, supporting causes from environmental sustainability to human rights. Recent beneficiaries include the Global Viral Forecasting Initiative and the Peace Works Network Foundation. Skoll's venture capital firm, Capricorn Investments, has stakes in TrueCar, Nanosolar, and Tesla Motors. He was named an Officer of the Order of Canada in December. Skoll was previously listed as a Canadian on Forbes World's Billionaires list; because he has obtained U.S. citizenship, we are now listing him as an American.
