The International Rescue Committee responds to the world’s worst humanitarian crises and help people to survive, recover, and gain control of their future. Founded in 1933 at the request of Albert Einstein, the IRC offers lifesaving care and life-changing assistance to refugees and displaced people forced to flee from war or disaster. At work today in over 50+ countries and in 28 U.S. cities, the IRC restores safety, dignity and hope to millions who are uprooted and struggling to endure.

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.
