Social entrepreneurs and market-driven organizations are those that hold themselves accountable to both social and financial outcomes; they advance their mission by building focused strategies and sustainable business models that address customer needs and yield competitive advantage. In order to apply these market-based approaches toward social solutions, leaders must first be equipped with skills and resources to build organizational capacity that can deliver results. Wendy Kopp, Founder and Executive Director of Teach for America, recently summarized this point during a convening at the Annie E. Casey Foundation of leaders across sectors: "There's nothing more important than talent and team in organization building as we think about how to get where we want to go". Teach for America address.
