Accelerating Supply & Deployment
C3 is seeking expressions of interest for funding to address persistent barriers in deployment, expand the pool of catalytic capital providers, or integrate both in ways that enhance the catalytic capital ecosystem. Submissions are due by March 4, 2026. Invitations for full proposals will be issued in April.
Investing in Field Partnerships
As part of C3, the MacArthur Foundation has invested in funds and organizations that demonstrate a powerful use of catalytic capital. Investments have been designed to reduce risk, build track records, increase the scale of promising fund managers, and set the stage for other investors to participate.
Strengthening the Evidence Base
C3 grants have funded 14 research projects to analyze the uses of catalytic capital around the world and help strengthen the evidence base for the field. The goal is to fuel additional risk-tolerant, flexible, and patient investments that address critical global challenges.
Fostering Solutions & Infrastructure
C3 grants have supported 12 plans to address barriers that create financing gaps and slow progress on critical social and environmental issues. Projects have been designed to accelerate the flow of catalytic capital and support impact that would not otherwise be possible.
