Pierre Omidyar, the founder of eBay, and his wife, Pam, established Omidyar Network based on the belief that every person has the potential to make a difference. Since 2004, they have worked with their partners to create opportunities for people to tap that potential, enabling them to improve their lives and make powerful contributions to their communities.
They support, scale, and champion the work of their partners in order to maximize social impact. As a philanthropic investment firm, they make both investments and grants, identifying like-minded organizations that they support, help scale, and collaborate with to help realize their full potential. Their efforts are organized around two investment initiatives—Access to Capital, and Media, Markets and Transparency.
