About Prosper Global (formerly Mercy Corps)
Barely enough is not enough for anyone. Prosper Global is a humanitarian organization working alongside communities facing conflict, climate change, and economic hardship to meet urgent needs and create the conditions for lasting progress. Today's challenges demand new solutions, so we pair local knowledge with global resources to help communities build what's needed, test what's possible, and scale what's proven so that people everywhere can pursue a full life on their own terms. In 2026, we changed our name from Mercy Corps to Prosper Global, to reflect our belief that when every community can prosper, all of humanity moves forward.
