About C3
C3 is an investment, learning, and market development initiative to promote greater and more effective use of catalytic capital and enable a more just, equitable, and resilient world.
Our Goal
C3 is now embarking on its next chapter, partnering with nine new impact investment leaders to expand the global catalytic capital community and fuel increased investments to advance the SDGs. In addition to ongoing support from MacArthur, new funders include Blue Haven Initiative, Builders Vision, Ceniarth, Ford Foundation, The Lemelson Foundation, Small Foundation, Sorenson Impact Foundation, Surdna Foundation, and Walton Family Foundation.
Grantmaking
Supporting field-building work. Funding helps to answer critical questions about the scope of the need for catalytic capital, identify when and how catalytic capital can be most effective, and demonstrate what tools and practices are needed, all in service of building a robust community of practice.
Investing
Deploying capital to funds and initiatives that demonstrate a powerful use of catalytic capital. Investments are meant to reduce risk, build track records, increase the scale of promising fund managers and set the stage for other investors to participate. The MacArthur Foundation has provided financing for C3-related investments.
