Tackling Diarrheal Disease in the Democratic Republic of the Congo (DRC) and South Sudan

| by GiveWell Staff

Diarrhea is one of the leading causes of death for children under five, killing more than 400,000 children every year. GiveWell has funded several programs to prevent and treat diarrhea, and we recently expanded our work by making a grant to support the implementation and evaluation of WASHmobile in the Democratic Republic of the Congo (DRC) and South Sudan. The program, which was developed by Johns Hopkins University, delivers water treatment supplies and hygiene messaging to households at the highest risk of diarrheal disease. It has shown promising results in randomized controlled trials (RCTs) but hasn’t yet been implemented at scale in the challenging settings where the need is greatest.

In this episode, GiveWell co-founder and CEO Elie Hassenfeld speaks with Senior Program Officer Erin Crossett, who leads GiveWell’s water research subteam, about the grant. They discuss how the program works, what prior research tells us about its potential, the significant uncertainties involved, and what GiveWell expects to learn.

Scaling Our Impact, With Support From a $1 Billion Commitment

| by GiveWell Staff

This year, we are focused on two primary goals. The first is to rapidly scale our research capabilities so we’re able to move much more donor funding to highly cost-effective programs in the near future. The second is to find and fund as many of the best opportunities we can this year to save and improve lives.

In 2025, we committed $418 million in grants. Though we’re just halfway through the year, we’ve already committed over $400 million in 2026. We anticipate our total grantmaking is likely to approach or even exceed $1 billion this year, and we are working toward a future that could be several times that scale.

We’re excited to share another major step in that direction. Coefficient Giving has decided to increase its near-term funding commitment for GiveWell grants to $1 billion in support of our continued scaling.

This commitment is both extraordinary and timely. Near-term needs continue to far surpass our fundraising expectations, and we are actively working to raise more funds to support a growing set of cost-effective opportunities to help people in need.

What’s driving our increased grantmaking

Several factors have driven our current expansion, as well as our ability to continue scaling.

Casting a Wider Net for Cost-Effective Programs

(updated on: ) | by GiveWell Staff

GiveWell tends to be known for its work in areas like malaria prevention, water treatment, and nutrition. But as our research team has grown, so has our ability to search for cost-effective programs across a much wider range of issues.

Serious health problems, such as lack of medical oxygen and stockouts of essential medicines at health facilities, affect millions of people in low-income countries. There may be highly cost-effective solutions to these problems that haven’t been thoroughly evaluated or adequately funded. One of the ways GiveWell is searching for these solutions is through the new areas research subteam, which is responsible for investigating programs in cause areas GiveWell hasn’t historically focused on.

In this episode, GiveWell co-founder and CEO Elie Hassenfeld speaks with Senior Program Officer Dan Brown about GiveWell’s new areas research subteam and three grants that illustrate the team’s work.
