Podcast Episode 22: Evolving Our Research Approach for Greater Impact

| by GiveWell Staff

GiveWell is often thought of for its Top Charities, but over the last several years, we’ve been substantially broadening our work. We’ve developed new ways to identify potential grantees, funded research to fill gaps in our understanding, and explored new program areas where we believe cost-effective opportunities exist but other funders aren’t investing. This increased breadth isn’t a goal in itself—we’ve been laying the groundwork to deliver more impact, now and in the future.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Senior Program Officer Julie Faller about how our research approach has evolved and what it means for the future of our grantmaking.

Podcast Episode 21: Testing Our Assumptions through Local Insights

| by GiveWell Staff

GiveWell has built its reputation on rigorous research—analyzing randomized controlled trials, building cost-effectiveness models, and reviewing monitoring data to identify cost‑effective ways to save and improve lives. In an effort to supplement this desk research and make better decisions, we’ve been working to gather more information directly from the people who live and work in the countries where we fund programs.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Principal Researcher Alex Cohen about GiveWell’s work to gather local insights to check our assumptions and figure out what we might be missing.

Podcast Episode 5: Exploring HIV/AIDS Funding Cuts and Emerging Needs

(updated on: ) | by GiveWell Staff

Historically, the US government has been a major funder of HIV/AIDS programs through PEPFAR and other initiatives, providing around $5 to $6 billion annually. With anticipated major reductions in US government foreign aid, including potential cuts of 20% to 50% to HIV/AIDS funding, GiveWell is assessing where new, cost-effective needs might emerge.

GiveWell aims to find programs where additional funding can have the greatest impact. While HIV/AIDS has not historically been a focus for GiveWell due to substantial US government support, the current funding cuts might lead to potential cost-effective opportunities within HIV/AIDS programming. In the latest episode in our podcast series, GiveWell CEO and co-founder Elie Hassenfeld speaks with Program Officer Alice Redfern about our initial exploration into HIV/AIDS programming.

What we fund, #1: We fund many opportunities outside our top charities

(updated on: ) | by Isabel Arjmand

GiveWell aims to find and fund programs that have the greatest impact on global well-being. We’re open to funding whichever global health and development opportunities seem most cost-effective. So while our top charities list is still what we’re best known for, it’s only part of our impact; we also dedicate substantial funding and research effort to opportunities beyond top charities.

In 2022, 71% of the funds we directed supported our four current top charities, and 29% were directed to other programs. However, most of our research capacity goes toward programs other than our top charities. This is because (a) most programs we direct funding to aren’t top charities (we have four top charities but directed funding to about 40 other grantees in 2022), and (b) it requires more effort to investigate a program we know less deeply.

In this post we’ll share:

  • The overall scope of our grantmaking
  • Why we dedicate funding and research capacity to programs other than our top charities
  • The types of opportunities we support
