Coefficient Giving

What Coefficient Giving does

Coefficient Giving is a San Francisco-based philanthropic funder and advisor, operating as a private nonprofit. Founded in 2014 under the name Open Philanthropy and rebranded in 2025, the organization directs grants to researchers, nonprofits, academic institutions, and—increasingly—biotech companies across 14 thematic funds covering Abundance & Growth, Air Quality, Biosecurity & Pandemic Preparedness, Effective Giving & Careers, Farm Animal Welfare, Forecasting, Global Aid Policy, Global Catastrophic Risks, Global Growth, Global Health & Wellbeing, Lead Exposure, Navigating Transformative AI, Science & Global Health R&D, and Strep A Vaccine development. Across these verticals, the organization has directed over $5 billion in grants since inception, including more than $1 billion in 2025 alone—the largest annual deployment in its history.

The platform's core mechanism is strategic cause selection research: the organization identifies high-impact intervention areas and deploys capital through competitive Request for Proposals (RFPs), multi-year program grants, and direct lead-equity investments. Notable transactions include a $45 million Series A lead in VST BIO (stroke therapeutics, March 2026), a $45–$48 million award to relaunch the DIV Fund for international development (early 2026), and targeted grants supporting alternative protein R&D, fish welfare research, malaria gene-editing, low-cost air quality sensors in India, and remote-sensing-based emissions detection. Grantees span academic institutions (UC San Diego, IIT Kanpur, IIT Bombay), nonprofits (Center for Responsible Seafood, DIV Fund, Open Wing Alliance), and biotech startups, with operating geographies covering North America, South Asia (India, Bangladesh), East Africa (Uganda), and Central America (Guatemala).

The business model is grantmaking funded by private philanthropy from a base of leading donors (with Dustin Moskovitz, co-founder of Facebook, serving as Chairman and co-founder). Coefficient does not sell products or services and does not generate commercial revenue; rather, it accepts charitable contributions and disburses them to grantees after rigorous vetting. Distribution occurs through direct relationships and RFP-based application processes, supported by content marketing (website, research publications, X, LinkedIn) and email newsletters aimed at both donor and grantee audiences. With 51–100 employees, the organization's value proposition centers on its scale, brand recognition, and demonstrated ability to convert donor capital into measurable global outcomes.

Direct peers

• Chan Zuckerberg Initiative (CZI): Large private philanthropic vehicle funded by a tech billionaire (Mark Zuckerberg), combining grantmaking, in-house R&D, and equity-style investments. Closely comparable to Coefficient in funder base, age cohort, and willingness to deploy philanthropic capital into companies and venture-style bets.
• Arnold Ventures: Large U.S. philanthropic foundation backed by a single high-net-worth donor (John Arnold), operating multiple thematic programs with rigorous research-driven strategy. Highly comparable operating model to Coefficient.
• Good Ventures: The original funder that seeded Open Philanthropy (now Coefficient Giving); continues to deploy hundreds of millions annually in effective altruism-aligned causes. Closely comparable donor base, cause-selection philosophy, and effective-altruism orientation.

Broad incumbents

• Ford Foundation: One of the largest U.S. private foundations, deploying over $1B annually across inequality, democracy, and development causes. Comparable grantmaking scale and global footprint.
• Bill & Melinda Gates Foundation: The world's largest private philanthropic foundation, deploying tens of billions across global health, development, and education. Directly comparable to Coefficient in operating model (strategic grantmaking, in-house research) but at substantially greater scale and with a broader health/development focus.
• Wellcome Trust: Major UK-based foundation focused on global health, mental health, and discovery research. Comparable to Coefficient in funding scientific R&D, vaccine development, and pandemic preparedness at scale.
• Bloomberg Philanthropies: Major philanthropic vehicle funded by a single billionaire (Michael Bloomberg) covering public health, environment, and cities. Comparable in single-donor-funded scale and multi-thematic structure, though less focused on AI/catastrophic-risk areas.
• Lilly Endowment: Large U.S. private foundation deploying over $1B annually across religion, education, and community development. Comparable in cumulative grantmaking scale and private-foundation structure.

Emerging players

• Founders Pledge: Effective-altruism-aligned philanthropic platform aggregating donations from tech founders. Comparable cause-selection methodology and donor base, though smaller in annual deployment than Coefficient.
• OpenAI Foundation / AI Safety Grants: Tech-company-affiliated grantmaking to AI safety and alignment research — directly overlapping with Coefficient's Navigating Transformative AI fund. Represents an adjacent funder in the same emerging AI-safety philanthropic category.
