Our Beyond the Spreadsheets mini-series lets you ride along with our leadership team on their recent weeklong site visit to Malawi. Recorded daily during the trip, the series shares the behind-the-scenes experience of a GiveWell site visit through real-time reflections and clips of conversations.
On day five, the GiveWell team visited a school in Lilongwe, where they spoke with school representatives and families of students in a nearby urban settlement. On day six, the GiveWell team stopped at a major hospital in Lilongwe to hear from hospital staff and an implementing partner about the impact of foreign aid funding cuts.
New to the series? Start with day one here.
Throughout the week, the team visited health clinics, schools, and local villages to speak with healthcare workers and community members who shared a glimpse into their lives. This mini-series offers a candid, day-by-day account of our learning process and some of the new insights and questions that will inform our future research.
This episode was recorded on August 3 and 4, 2025 during GiveWell's site visit to Malawi and represents our best understanding at that time.

In an effort to direct substantially more funding to the most cost-effective opportunities we can find to help people, GiveWell’s research is expanding in two directions at once: going broader, to cover more areas of global health and development, and going deeper, to improve the inputs that inform our decision-making.
GiveWell works to continually improve our research so we can make better grant decisions and direct donations where we believe they can do the most good. GiveWell’s Cross-Cutting research subteam is an important part of that effort—it investigates the impact of the programs we fund, works to resolve our largest uncertainties, and aims to improve our research. As GiveWell’s grantmaking grows, the Cross-Cutting subteam is strengthening our data collection and analysis to support that growth. In this episode, GiveWell co-founder and CEO Elie Hassenfeld speaks with Program Director Alex Cohen, who leads the Cross-Cutting subteam, about how better data can improve our decision-making, our work to gather stronger evidence, and the ways we’ve tested AI as a tool to increase our research capacity and quality.
GiveWell, with co-funding from Coefficient Giving, recently made our largest grant to date: $276 million to the Against Malaria Foundation (AMF) to support the procurement and distribution of 92 million nets in the Democratic Republic of the Congo (DRC) from 2027 through 2029. We estimate that the nets, 46 million of which we think would not otherwise be distributed, will avert roughly 67,000 deaths. We have supported AMF’s work for more than 15 years, and the insecticide-treated nets it procures and distributes remain one of the most cost-effective ways we've found to save lives.
When GiveWell investigates a new cause area, we’re often focused on two priorities: directing funding where we think it can help people most and generating evidence to inform larger investments later. Family planning is a clear example. Recent foreign aid cuts—including reductions from the US, UK, and Dutch governments—deepened an already substantial need and opened up new cost-effective funding opportunities.
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.
