Press Release: Open Philanthropy Becomes Coefficient Giving, Expanding Work With Multiple Donors

Change reflects organization’s growing role as advisor to many major philanthropists

Coefficient Giving has directed more than $4 billion in giving since 2014

SAN FRANCISCO – Today, philanthropic funder and advisor Open Philanthropy announced it is becoming Coefficient Giving, reflecting its evolution from working primarily with one philanthropic partner to supporting multiple major donors pursuing cost-effective, high-impact giving.

Since its founding, Coefficient Giving has directed more than $4 billion in philanthropic funds, working closely with Good Ventures, the charitable foundation of Dustin Moskovitz and Cari Tuna. In recent years, it has begun advising a growing range of other donors on their philanthropy, directing more than $100 million in funding from donors beyond Good Ventures in 2024 and more than doubling that amount so far in 2025.

“We’ve spent the last decade building a model for giving effectively at scale,” said Alexander Berger, CEO of Coefficient Giving. “There is still so much more that philanthropy can do today to improve the world, and this change reflects our growing work with many philanthropists. Our goal is simple: move more money to the world’s highest-impact opportunities, and make it easier for others to do the same.”

As part of its next chapter, Coefficient Giving’s existing programs are becoming multi-donor funds that philanthropists can join to support specific cause areas, including Science and Global Health R&D, Global Aid Policy, Abundance & Growth, and more. The organization’s mission remains the same: to help others as much as it can with the resources available.

“Open Philanthropy has been a fantastic partner on high-impact giving,” said Bill Gates, Chair of the Gates Foundation. “This evolution of their work has great potential to bring other givers into neglected areas where they can make a huge difference in the lives of people around the world.”

Coefficient Giving’s recent growth builds on a decade of results. Its grantmaking has saved an estimated 100,000 lives through global health interventions, supported Nobel Prize-winning research on using AI to design proteins, helped launch the Yes In My Backyard (YIMBY) Movement, and improved the lives of more than 3 billion farm animals, among other successes. In the last two years, it launched two major pooled funds — the $125 million Lead Exposure Action Fund and the $120 million Abundance & Growth Fund — expanding its model of collaborative, cost-effective giving to a broader ecosystem of partners and funders.

“Our partnership with the Coefficient Giving team has been essential to our philanthropy over the past 15 years,” added Cari Tuna, Chair of Good Ventures. “Our intention is to take the fullest possible advantage of the opportunity we have to help others, and Coefficient’s rigorous, analytical approach — from choosing causes to making grants — gives us more confidence that we’re on track. I’m excited to see them expand their model so more donors can amplify their impact.”

The new name reflects the organization’s mission and approach: a coefficient multiplies the value of what it’s paired with, just as Coefficient Giving works with donors and grantees to amplify their impact.
