The document proposes a Social Good Ecosystem Incubator model to support pre-proof of concept social ventures. It suggests structuring the incubator as an ecosystem where established organizations help offset costs for early-stage ventures. A technology layer across projects would provide visibility and collaboration. A Social Good Ecosystem Pooled Fund would provide cash for projects through structures like bonds that guarantee investor principal while funding the incubator ecosystem. The model aims to proliferate social entrepreneurship by supporting many small ventures rather than just one large venture.
