This is a fundraiser to help professionals get 100-1000x more impact from their charitable donations. There are millions of nonprofits in the world, all promoting worthy causes and all in need of more funding. With such a bewildering array of options, how do we decide where to give most effectively?

This fundraiser offers three different places to have some of the biggest possible impact with a one-off donation:

Against Malaria Foundation, which aims to provide long-lasting insecticidal nets to populations at high risk of malaria, primarily in Africa.

New Incentives, which believes that “no child should die of a preventable disease” and that “small cash incentives are a proven, cost-effective way to boost vaccination rates and save lives.”

Helen Keller International's Vitamin A Supplementation Program, a charity on a mission to deliver the essential building blocks of good health, sound nutrition, and clear vision to help millions of people create lasting change in their own lives.

On average, donating $3,000 to $4,500 will help these charities protect enough people that someone would have otherwise likely died (and many more would’ve gotten very sick) had that amount not been donated!
