A Philadelphia-based non-profit organization dedicated to supporting and expanding communities of entrepreneurs and professionals that promote economic, technological, and cultural viability for sustainable practices. We envision true sustainability - a world in which social, environmental and economic systems are understood and managed as deeply interdependent- and seek to build networks and infrastructure to support that vision. Our mission is to accelerate our progression toward true sustainability by establishing uniquely respondent regional centers that coalesce the abundant but fragmented energy and talent already flowing into social and environmental sustainability goals in each region.
