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.
