Philanthropy and social innovation are two sides of the same coin. Social innovators cannot achieve significant social impact without the financial capital to support their ideas. Philanthropists cannot achieve significant social impact without the vision and creativity of a social entrepreneur. The most successful social ventures are those where social innovators and philanthropists are true partners united around a common mission and vision. But, how do you create that perfect partnership? This session will be a frank discussion among individual philanthropists, foundation leaders, and social entrepreneurs about the impact they seek, how they measure success, and lessons they have learned from past partnerships.
