Open Philanthropy is a philanthropic advisor and funder. We are made up of several affiliated organizations that research potential focus areas, investigate giving opportunities, make grants and investments, evaluate our impact, and support donors who partner with us to pursue high-impact giving at scale. 

We advise and make recommendations to a wide range of donors, though our main funders — Cari Tuna and Dustin Moskovitz — account for most of our grantmaking and cover our operational costs. The grants we recommend are awarded by a variety of entities, most commonly the Good Ventures Foundation, donor-advised funds, the Open Philanthropy Action Fund (a 501(c)(4) social welfare organization), and Open Philanthropy Advisors (a 501(c)(3) public charity that houses multi-donor collaboratives like the Lead Exposure Action Fund and the Abundance and Growth Fund).

Open Philanthropy staff who primarily conduct research (including researching potential cause areas and evaluating our impact) are typically employed or contracted by the Open Philanthropy 501(c)(3), a nonprofit research organization. Staff who investigate and recommend grants or investments, distribute funds to grantees, and provide operations support are typically employed or contracted by the Open Philanthropy LLC. Good Ventures does not currently have employees of its own and instead relies on the research and recommendations of staff employed by Open Philanthropy.

The Open Philanthropy LLC is governed by a Board of Managers currently consisting of Cari Tuna (Chair of the Board), Dustin Moskovitz, Elie Hassenfeld, and Alexander Berger. The Open Philanthropy 501(c)(3) is governed by a Board of Directors currently consisting of Cari Tuna (Chair of the Board), Dustin Moskovitz, Divesh Makan, and Alexander Berger.
