Coefficient Giving is a philanthropic funder and advisor that partners with leading donors to multiply their impact. Formerly Open Philanthropy, the organization has directed over $5 billion in grants since 2014, including more than $1 billion in 2025 alone, and works with donors such as Good Ventures and other major philanthropists to identify and fund high-impact giving opportunities.
Coefficient operates dedicated funds spanning global health and wellbeing, biosecurity and pandemic preparedness, farm animal welfare, global growth, AI safety, science and global health R&D, air quality, and other strategic cause areas.
Coefficient Giving selects causes using three criteria: importance, geglectedness, and tractability. The organization applies worldview diversification by allocating resources across multiple compelling approaches to doing good, from proven global health interventions to high-risk bets on transformative AI governance and catastrophic risk reduction.
Its hits-based giving strategy accepts that many grants may fail in pursuit of a few breakthrough successes, while cost-effectiveness analysis helps direct funding to opportunities with the highest expected impact per dollar. Coefficient also provides research, strategic guidance, and operational support to partner donors seeking to maximize the impact of their philanthropy.
