Open Philanthropy
Coefficient Giving (formerly Open Philanthropy ) is an American philanthropic advising and funding organization. Its current CEO is Alexander Berger. [ 1 ]
As of June 2025, Coefficient Giving has directed more than $4 billion [ 1 ] in grants across a variety of focus areas, including global health, scientific research, pandemic preparedness, potential risks from advanced AI, and farm animal welfare. It chooses focus areas through a process of "strategic cause selection" — looking for problems that are large, tractable, and neglected relative to their size. [ 2 ]
History
[ edit ]
While Coefficient Giving works with a range of donors, its founding and most significant ongoing partnership is with Good Ventures , the foundation of Cari Tuna and Dustin Moskovitz .
Former logo of the organization, before it was renamed Coefficient Giving in 2025.
Dustin Moskovitz co-founded Facebook and later Asana , becoming a billionaire in the process. He and Tuna, his wife, were inspired by Peter Singer 's The Life You Can Save , [ 3 ] and became the youngest couple to sign Bill Gates and Warren Buffett's Giving Pledge , promising to give away most of their money. Tuna left her journalist position at The Wall Street Journal to focus on philanthropy full-time, and the couple started the Good Ventures foundation in 2011. The organization partnered with GiveWell , a charity evaluator founded by Holden Karnofsky and Elie Hassenfeld . The partnership named itself the "Open Philanthropy Project" in 2014, and began operating independently in 2017.
More recently, Open Philanthropy has launched collaborative funds in partnership with philanthropic donors, including the Lead Exposure Action Fund and the Abundance and Growth Fund. [ 1 ] In November 2025, Open Philanthropy was renamed Coefficient Giving, signaling an expansion toward operating multi-donor funds that other philanthropists can join. [ 1 ] [ 4 ] [ 5 ] Bill Gates has referred to the organization as “a fantastic partner on high-impact giving.” [ 6 ]
