What are Social Impact Infrastructure Organizations? Social impact infrastructure organizations (SIIOs) are the accelerators, connectors, conveners, educators, platforms, orchestrators, researches, and trainers that enable the rest of us to effectively impact change. Some SIIOs help their funding members give away billions of dollars more effectively. Some increase social impact investments, accelerate innovations, improve the capacities of nonprofit and civil society organizations, partner with governments and other sectors, and more.

Why Support Social Impact Infrastructure Organizations?
Because of their far reach, there are times when even small grants to SIIOs can drive big results. We have collected numerous examples on our Stories of Impact Page.
