# Coefficient Giving ## Basic Info **Name:** Coefficient Giving (formerly Open Philanthropy) **What is it:** American philanthropic research and grantmaking organization. Selects causes based on importance, neglectedness, and tractability, then pools donor money into thematic funds. Has directed over $4 billion in grants since 2014. Rebranded from Open Philanthropy in November 2025 to reflect its shift toward operating multi-donor pooled funds that other philanthropists can join — rather than working primarily with a single funder. **Location:** San Francisco, USA **Link:** https://coefficientgiving.org **Who is involved:** CEO Alexander Berger; Chair Cari Tuna. Primary funders are Cari Tuna and [[Dustin Moskovitz]] (Facebook co-founder) through their Good Ventures foundation. Other partners include [[Patrick Collison]], the [[Gates Foundation]], and others. The organization runs 13 thematic funds spanning global health, AI risk, biosecurity, farm animal welfare, innovation policy, and more. --- ## Entries [[2026-02-21]]: [Abundance and Growth Fund](https://coefficientgiving.org/funds/abundance-and-growth/) - Discovered through [The Abundance and Growth Blog](https://abundanceandgrowthblog.substack.com/about) (the fund's Substack). Launched in March 2025 with at least $120 million over three years. Led by [[Matt Clancy]] (PhD in economics, previously led Coefficient's Innovation Policy program). Team includes [[Alex Armlovich]] (housing policy, ex-Niskanen Center), [[Jordan Dworkin]] (innovation policy, ex-Federation of American Scientists), Willow Latham-Proença (energy, ex-Congressional Budget Office), and [[Dylan Matthews]] (state capacity and new areas, ex-Vox). - The fund builds on a decade of work funding the YIMBY movement and innovation policy. It now expands into permitting reform, energy infrastructure, clinical trials, and state capacity. The core thesis is that well-intentioned regulation and institutional sclerosis are artificially creating scarcity, and that philanthropy can help remove these constraints.
