In today's complex world we face both peril and possibility. With grave social and environmental challenges to our collective future, a growing number of social innovators and their supporters are taking bold action. They are becoming intentional about shifting structures cultures and institutions. Such practices are not yet wide-spread. For years many funders have been supporting diverse social innovations and experimenting with approaches to "scaled-up" grantmaking But our efforts have often been too narrow or short-term and the results uneven Wisdom and experience now suggest that we need a clear vision, firm commitment, and persistence to remove the barriers to enduring social change. The purpose of this paper is to contribute to an emerging body of knowledge and reflective practice on the role of funders in supporting innovation and social change.
