In December 2025, we committed $175 million for 2026 to GiveWell's evidence-backed, cost-effective recommendations in global health. In partnership with Good Ventures, we're now increasing that commitment to $1 billion.

Our new name marks our next chapter as we double down on our longstanding goal of helping more funders increase their impact. We believe philanthropy can be a far more vital force for progress than it is today.
A coefficient multiplies the value of whatever it’s paired with, just as we aim to amplify impact through our research, grantmaking, and partnerships. We knew that any name would take some getting used to, but this one captured something essential about our work.
