Open Philanthropy Rebrands to Coefficient Giving, Expands Donor Base

2 hours ago7 min read

In a move that signals a significant evolution for one of the world's most influential philanthropic organizations, Open Philanthropy is rebranding to Coefficient Giving. This isn't merely a cosmetic change; it's a strategic pivot from operating primarily as the philanthropic arm for Facebook and Asana co-founder Dustin Moskovitz and his wife Cari Tuna’s Good Ventures foundation, to establishing itself as a multi-donor collaborative.Over the past decade, Open Philanthropy has directed over $4 billion with a rigorous, analytical approach, saving an estimated 100,000 lives, catalyzing the YIMBY movement in California, and supporting research that later won a Nobel Prize. Its methodology, deeply intertwined with the principles of effective altruism, has been a grand experiment in applying a cost-benefit analysis framework to global problem-solving.Now, under the new moniker Coefficient Giving, the organization aims to become a multiplier, a force that amplifies impact by pooling resources from a broader base of philanthropists. The name itself is a carefully chosen piece of semiotics: the 'co-' emphasizes collaboration, while the 'efficient' reaffirms an unwavering commitment to maximizing the return on every charitable dollar invested.This shift is already operational, with internal programs being converted into multi-donor funds like the $125 million Lead Exposure Action Fund and the $120 million Abundance and Growth Fund, which other givers can join. In 2024, the organization directed more than $100 million from donors beyond its anchor funders, a figure that has more than doubled in 2025.CEO Alexander Berger, a pragmatic optimist who has steered the organization through bets on everything from AI risk to global health, frames this not as solving a problem but as fulfilling the original, long-term ambition of becoming a resource for others asking the fundamental question: where can my resources do the most good? This transition occurs at a critical juncture. The landscape of public funding is increasingly volatile, with slashed budgets at agencies like USAID and the NIH, while private tech wealth—and the existential questions surrounding artificial intelligence—surges.Philanthropy’s unique role, as Berger articulates it, lies in addressing areas where there is a 'structural imbalance in power or resources,' such as developing medical technologies for diseases that don't afflict the rich world or advocating for future residents who can't yet vote for pro-housing policies. The rebrand also subtly distances the organization from the sometimes-insular label of 'effective altruism,' aiming to be a resource for a wider audience that may never have heard of the movement.This is a mature step for an entity that has learned the hard limits of predicting 'tractability' and has instead doubled down on funding highly important and deeply neglected causes, accepting that many high-risk bets, like early funding in AI safety and protein design, will fail, but the ones that succeed can be world-changing, as evidenced by their early backing of Nobel laureate David Baker. The second act for Coefficient Giving is a test of whether this multiplier model can indeed deliver more impact, faster, in a world desperately in need of both efficiency and hope, navigating the delicate balance between near-term humanitarian crises and long-term existential risks with the steady hand of those who understand that true progress is often measured in decades, not fiscal quarters.
