SIIOs are the connectors, conveners, accelerators, trainers, educators, researchers, and platforms that enable the rest of us to effectively impact change. Some SIIOs help donors 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 more.
To understand these organizations better, read our first-of-its-kind report, Illuminating the Invisible. Also visit our growing Directory page that showcases social impact infrastructure organizations worldwide.
