Description
The MacArthur Foundation’s Impact Investments program is designed to advance the field of impact investing by providing catalytic capital—flexible, patient, and risk-tolerant investments—to address critical social and environmental challenges worldwide. The initiative supports enterprises, nonprofits, funds, and special projects that drive inclusive economic growth, climate solutions, equity, and innovation in the finance and investment sectors. The program also strengthens the impact investing ecosystem through field-building grants, knowledge sharing, and collaborative initiatives such as the Catalytic Capital Consortium and Benefit Chicago. Funding supports both direct investments and grants to organizations that foster systemic change, mobilize additional capital, and advance the United Nations Sustainable Development Goals.
