Our Fellows

We find founders who have a scalable solution to climate or poverty—and the chops to deliver it.

Healthcare, education, livelihoods, nutrition, a healthy environment— whatever leads to a better life and a route out of poverty. Each year, we recruit the best twenty we can find into our Rainer and Henry Arnhold Fellows programs.
