Pierre Omidyar founded online marketplace eBay Inc. and still serves as its chairman. But these days, he would much rather talk about Omidyar Network, the philanthropic investment firm he started after leaving day-to-day duties at eBay in 1998.
Omidyar Network makes donations to nonprofits and also invests in for-profit organizations focused on social change. It is especially supportive of charitable technology initiatives. The 44-year-old Mr. Omidyar also has contributed significant personal wealth to such causes, recently passing the $1 billion mark in donations.
