Even with modest beginnings, “systems-change organizations” seek world-changing outcomes. But solving complex social problems is uniquely challenging. This resource surveyed “field catalysts” aiming for systems change across a variety of issues, including health equity, gender-based violence, climate change, and education. It found that their work could be accelerated with the right support from funders. Because these organizations consistently punch far above their weight, 87% of field catalysts believe they would achieve their systems-change goals within just two decades if provided the necessary resources and consistent support. This resource also profiles some organizations, including IllumiNative, Harambee Youth Employment Accelerator, South African National AIDS Council, Community Solutions, Health Care Without Harm, Movement for Black Lives, Families and Workers Fund, and more.
