Open Philanthropy is made up of several affiliated organizations that research potential focus areas, investigate giving opportunities, make grants and investments, and evaluate our impact.

We typically recommend grants to a donor-advised fund at the Silicon Valley Community Foundation. Support for the fund comes primarily from our main funders, Cari Tuna and Dustin Moskovitz, though historically other donors have contributed as well. In some cases, we make grants directly from the Open Philanthropy 501(c)(3) or make recommendations to Good Ventures, the Open Philanthropy Action Fund (a 501(c)(4) social welfare organization), or to other entities, including some that are not primarily funded or controlled by Dustin or Cari. Although the majority of our funding recommendations are directed to 501(c)(3) organizations, we also recommend contributions to other kinds of organizations when we believe that the programmatic benefits justify them.

Staff who research potential focus areas or advance academic or scientific research or education are typically employed by the Open Philanthropy 501(c)(3), a nonprofit organization that primarily conducts research. Staff who investigate and recommend non-research grants or investments, distribute funds to grantees, and evaluate our impact are typically employed by the Open Philanthropy LLC. Good Ventures does not currently have employees of its own and instead largely relies on the research and recommendations of staff employed by Open Philanthropy. 

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