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

The Catalytic Capital Consortium (C3) is a collaborative effort launched in 2019 to to increase the knowledge, awareness, and use of catalytic capital–a vital form of impact investing that is patient, risk-tolerant, concessionary, and flexible in ways that differ from conventional investment.

Through both grantmaking and investing programs, C3 is demonstrating the power of catalytic capital as synergistic with other forms of investing across the full continuum of capital (including commercial rates of return) to safeguard the environment, support those most in need, and ultimately to help achieve the UN Sustainable Development Goals (SDGs).

The C3 Strategic Partners—The Rockefeller Foundation, the Omidyar Network, and the MacArthur Foundation—are jointly funding the $10 million grantmaking work; MacArthur is financing more than $123 million in C3-related investments. This website seeks to capture a range of critical catalytic capital information in one place for the benefit of the field.


Supporting field-building work, helping to answer critical questions about the scope of the need for catalytic capital, identifying when and how catalytic capital can be most effective, and demonstrating what tools and practices are needed. Grants and contracts are supported by C3's strategic partners.


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 provides financing for C3-related investments.
