The world of giving is filled with well-meaning and talented individuals from every background. These influential altruists are making their mark on philanthropy.

Pierre Omidyar and Matt Bannick, Omidyar Network
After starting and later shuttering his own nonprofit, eBay founder Omidyar (left) became convinced that using business tools was a better way to solve social problems. So in 2004 he launched Omidyar Network, an organization that pairs a traditional foundation with a for-profit venture fund. Matt Bannick, the former president of eBay International, runs the firm, which has already made $120 million in investments.

They're supporting nonprofits like Donorschoose.org, which gives kids school supplies, as well as enterprises like Prosper.com, a consumer lending site, helping Omidyar Network to become as big a name in the social sector as eBay is in the dot-com world.
