We are trusted as one of the most transparent, high-impact charities.

Ready to make an impact?

Our funds enable donors to provide flexible, strategic support that epitomizes our value “think big, act urgently.” Investments in these funds are used to take advantage of emerging opportunities, fill critical programmatic funding gaps, and expand our impact.

High Impact School Health Fund

Investing in school health provides important benefits now and into the future. When children are healthy and able to attend school, productivity and future economic prospects grow exponentially. Fittingly, delivery of critical health programs in schools is one of the most cost-effective ways to improve children’s lives. Our established model, leveraging government infrastructure and human capital (teachers!), allows us to reach millions of children.

Deworm the World has been so effective that we are close to declaring victory in the fight against parasitic worms in several geographies. We’ve already used our platform and expertise to launch iron and folic acid supplementation in India. We can expand these programs to new geographies where millions of children need treatment and other high-impact yet underfunded health solutions that we can help deliver at schools, such as HPV vaccines. Maximize your investment and our existing partnerships to improve children’s lives – today and into the future.

Safe Water Now Fund

Safe water is essential for life. Investing in water quality helps fill a critical gap: water access alone isn’t enough. Wells and boreholes built by governments and NGOs are the first step — our safe water work ensures that children and families get the critical health benefits that water treatment provides. And this work uses existing water infrastructure, providing incredible leverage and value for money when it comes to saving a child’s life!

We’re expanding and scaling water treatment interventions we know work, and continuing to test complementary ones that can reach even more people. Your investment will help fund the most urgent and compelling safe water opportunities, improving the health of children and communities.

Radical Scale Fund

We’re constantly on a quest to find solutions to the challenge of poverty — some of these are new, some overlooked. But whatever the solution, once we’re convinced of its return on investment, we’re determined to deliver it with the greatest impact and value for money. We only scale what we have tremendous confidence in – and can steadfastly commit to our donors that we stand behind.

We’re pushing the limits of expansion and innovation: looking to bring existing solutions to new geographies, and challenging ourselves to have the best delivery models out there. And because of investments over the last decade in our programs, country presence, and Accelerator, we now have more shovel-ready opportunities than funding to deliver them – and the backing of some meticulous charity evaluators to boot. Investing in our Radical Scale Fund enables us to be bold and nimble – to take advantage of the most urgent and promising opportunities for outsize impact.
