Clubfoot, a congenital condition where children are born with one or both feet twisted inward, affects roughly one in 800 newborns globally. Most of those cases are in low- and middle-income countries, where only about 20% of children with clubfoot receive treatment. While most donations to GiveWell are directed to programs that reduce child mortality, our growing research capacity over the last several years has expanded what we’re able to evaluate and fund. One outcome of that work is that we’re better able to direct donations to highly cost-effective programs addressing disabling conditions, like clubfoot, and meaningfully improve quality of life.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Program Officer Meika Ball about GiveWell’s grant to MiracleFeet, an organization that expands access to clubfoot treatment. Their conversation walks through MiracleFeet’s program, how we estimated its cost-effectiveness, and Meika’s recent site visit to see the program in action in Côte d’Ivoire.

Vitamin A supplementation is one of the programs GiveWell has supported the longest, and we’re currently funding it in many African countries. The program has an unusually strong evidence base for reducing child mortality, with multiple randomized controlled trials. Yet, as is the case for most global health programs, the evidence for vitamin A supplementation has complex, unresolved questions, such as how well findings from decades-old trials apply today and the extent to which existing research has been influenced by publication bias. As GiveWell’s research team has grown over the last several years, we have expanded our capacity to carefully research these questions.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Senior Researcher Stephan Guyenet about the evidence base for vitamin A supplementation, the complications in applying that evidence to our funding decisions, and how GiveWell has improved our cost-effectiveness estimates for the program.

The post March 2026 Updates appeared first on The GiveWell Blog.

GiveWell’s primary focus has always been researching, identifying, and directing donations to programs we believe will do the most good. When GiveWell first started, we approached this by looking for organizations that were already delivering highly cost-effective, evidence-backed programs and directing funding to those programs. Over time, we were able to focus further upstream by first identifying highly cost-effective programs and then supporting the development of organizations to deliver them.

We’ve been able to take an even more expansive view as our research team doubled in size over the last several years. In addition to our core grantmaking, we’re now funding an increased number of grants designed to provide information that we think will help us direct more funding to highly cost-effective programs in the future. This includes things like generating research about program effectiveness, scoping new promising programs, and piloting program variations.

GiveWell has long made some grants aimed at improving our knowledge base, but this work has now grown substantially and become more systematic. In 2025, GiveWell made 18 grants, totaling approximately $39 million, that were aimed specifically at getting more information to improve future funding decisions. In our latest podcast episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Program Director Julie Faller about these “value of information” grants.

Over the past several years, GiveWell has been focused on growing, deepening, and improving our research team’s work in line with our core values of truth-seeking and transparency. As part of that effort, we’ve invited anonymous assessment of our grantmaking process in order to learn and improve.

In July 2024, we sent out our first anonymous survey to people we’ve worked with during grant investigations. While we typically ask for candid, live feedback from the organizations we work with, we had not previously invited anonymous assessment of our grantmaking process. The survey sought to better understand the extent to which we live out our values in our interactions with external organizations. The questions focused on organizations’ experiences with our grant investigation process and post-grant follow-up.

In 2025, we repeated the process with the same survey instrument and compared results to the prior year, to see what had changed and whether our daily work is reflecting our core values and operating principles.

GiveWell’s second annual grant investigation survey was sent to organizations that participated in our grant investigation process from April 2024 through July 2025. We invited a total of 122 individuals representing 75 organizations to participate, and we received 80 responses (66% response rate). Included in the total were 22 contacts from investigations that did not result in a grant, from which we received five responses.

GiveWell aims to find and fund programs that will do the most good per dollar. To do this, we carefully evaluate potential grants before making them—assessing academic evidence, building cost-effectiveness models, and talking to people in the sector who know the program well.

But our work doesn’t stop there. When a program we’ve supported nears the end of their funding, we also regularly evaluate its results to decide whether to continue our support. This typically involves gathering and analyzing extensive monitoring data. In most cases, the results are consistent with what we expected, and we renew the programs’ support. But sometimes we decide that, even if a program is doing a lot of good, it may not be having the impact we expected. In that case, we decide not to renew our support and instead direct those funds to where we think they’ll do much more good for people in need.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Senior Program Officer Erin Crossett about the research that led GiveWell not to renew support for Evidence Action’s Dispensers for Safe Water—a program that installs chlorine dispensers at rural water points so that households can treat their drinking water and reduce waterborne disease—in Malawi and Uganda.

GiveWell is launching two new requests for information (RFI) to expand GiveWell’s funding for vaccination outreach and anemia control programs. We’re excited to replicate the success of last year’s water chlorination RFI and explore how to reach even more people in low- and middle-income countries with programs to save and improve lives.

The first RFI seeks organizations that would like to implement targeted vaccination outreach or mobile vaccination programs in Democratic Republic of the Congo (DRC), Nigeria, or Somalia. The second seeks programs that reduce iron deficiency anemia through large-scale food fortification, targeted iron supplementation, and iron biofortification in Africa.

These RFIs are just one component of our expanding efforts to find and fund high-impact ways to help people in need. We’re making them public in an effort to reach as many organizations as possible, and we encourage you to share them with your networks. Submissions for both RFIs are due March 27.

In our 2025 grantmaking year, GiveWell approved $418 million in grants to highly cost-effective programs in order to save and improve lives as much as we can. Through years of deliberate groundwork, we’ve been growing our research capacity and scope in order to direct substantially more funding to the most impactful opportunities we can find. Last year’s grantmaking reflects this growth, and we will be continuing an intensive effort this year to scale our ability to partner with donors to help people in need.

Between February 1, 2025, and January 31, 2026, GiveWell approved 131 grants to 69 organizations—the most grants we’ve made in a year so far. This post provides an overview of the kinds of grants we made and the impact we had last year. This was only possible thanks to the generosity of our donors. We’re incredibly grateful for the trust you place in our research and for your partnership in trying to do the most good we can together.

In 2025, we launched more than 200 formal grant investigations, after reviewing many additional promising opportunities. Tens of thousands of hours went into this research, which resulted in 131 approved grants. This is more than double the number of grants we approved during 2024, and resulted in a year-over-year increase of more than 20% in total grantmaking dollars.

Vaccines are remarkably effective at preventing deadly diseases, and, while global needs for them are great, vaccines already receive substantial global funding. This creates a challenge: How do you identify opportunities where additional funding can meaningfully increase vaccination rates and save lives?

GiveWell has long recognized the potential for highly cost-effective vaccine programs. We started supporting vaccination programs in 2015 and have made over $200 million in vaccination-related grants to date. For example, New Incentives, one of our Top Charities, aims to increase routine childhood vaccinations in northern Nigeria by providing small cash incentives to caregivers who bring their children into clinics for vaccinations.

Over the past several years, we’ve been growing our research team and laying the groundwork to expand the scope of our work and funding.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Natalie Crispin, who leads GiveWell’s vaccination grantmaking. They discuss how our research approach has evolved and what it means for helping more children access life-saving vaccinations.
