Why We Support This Work

Impact investing is a powerful catalyst for global progress. Yet, worldwide, there is a multi-trillion-dollar shortfall in capital dedicated to addressing social needs. Access to capital remains a major challenge for organizations working to build a more just, inclusive, and sustainable world. 

What We Are Doing

We make flexible, patient, and risk-tolerant investments in funds and projects that spur inclusive economic growth, contribute to solutions to the climate crisis, and advance equity and inclusion.
