Why We Support This Work

Impact investing is a powerful catalyst for global progress. Access to capital remains a major challenge for enterprises, non-governmental organizations, and funds that are working to build a more just, inclusive, and sustainable world. Worldwide, there is a multi-trillion-dollar shortfall in capital dedicated to addressing social needs, according to the United Nations, dampening progress on poverty, global health, climate change, inequality, and other problems outlined in the United Nation's Sustainable Development Goals.

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.
