Open Philanthropy donations made to Animal Charity Evaluators

This is an online portal with information on donations that were announced publicly (or have been shared with permission) that were of interest to Vipul Naik. The git repository with the code for this portal, as well as all the underlying data, is available on GitHub. All payment amounts are in current United States dollars (USD). The repository of donations is being seeded with an initial collation by Issa Rice as well as continued contributions from him (see his commits and the contract work page listing all financially compensated contributions to the site) but all responsibility for errors and inaccuracies belongs to Vipul Naik. Current data is preliminary and has not been completely vetted and normalized; if sharing a link to this site or any page on this site, please include the caveat that the data is preliminary (if you want to share without including caveats, please check with Vipul Naik). We expect to have completed the first round of development by the end of March 2022. See the about page for more details. Also of interest: pageview data on, tutorial in README, request for feedback to EA Forum.

Brief history: Open Philanthropy (Open Phil for short) spun off from GiveWell, starting as GiveWell Labs in 2011, beginning to make strong progress in 2013, and formally separating from GiveWell as the "Open Philanthropy Project" in June 2017. In 2020, it started going by "Open Philanthropy" dropping the "Project" word.

Brief notes on broad donor philosophy and major focus areas: The Open Philanthropy Project is focused on openness in two ways: open to ideas about cause selection, and open in explaining what they are doing. It has endorsed "hits-based giving" and is working on areas of AI risk, biosecurity and pandemic preparedness, and other global catastrophic risks, criminal justice reform (United States), animal welfare, and some other areas.

Notes on grant decision logistics: See for the general grantmaking process and for more questions that grant investigators are encouraged to consider. Every grant has a grant investigator that we call the influencer here on Donations List Website; for focus areas that have Program Officers, the grant investigator is usually the Program Officer. The grant investigator has been included in grants published since around July 2017. Grants usually need approval from an executive; however, some grant investigators have leeway to make "discretionary grants" where the approval process is short-circuited; see for more. Note that the term "discretionary grant" means something different for them compared to government agencies, see for more.

Notes on grant publication logistics: Every publicly disclosed grant has a writeup published at the time of public disclosure, but the writeups vary significantly in length. Grant writeups are usually written by somebody other than the grant investigator, but approved by the grant investigator as well as the grantee. Grants have three dates associated with them: an internal grant decision date (that is not publicly revealed but is used in some statistics on total grant amounts decided by year), a grant date (which we call donation date; this is the date of the formal grant commitment, which is the published grant date), and a grant announcement date (which we call donation announcement date; the date the grant is announced to the mailing list and the grant page made publicly visible). Lags are a few months between decision and grant, and a few months between grant and announcement, due to time spent with grant writeup approval.

Notes on grant financing: See or for more information. Grants generally come from the Open Philanthropy Project Fund, a donor-advised fund managed by the Silicon Valley Community Foundation, with most of its money coming from Good Ventures. Some grants are made directly by Good Ventures, and political grants may be made by the Open Philanthropy Action Fund. At least one grant was made by Cari Tuna personally. The majority of grants are financed by the Open Philanthropy Project Fund; however, the source of financing of a grant is not always explicitly specified, so it cannot be confidently assumed that a grant with no explicit listed financing is financed through the Open Philanthropy Project Fund; see the comment for more information. Funding for multi-year grants is usually disbursed annually, and the amounts are often equal across years, but not always. The fact that a grant is multi-year, or the distribution of the grant amount across years, are not always explicitly stated on the grant page; see for more information. Some grants to universities are labeled "gifts" but this is a donee classification, based on different levels of bureaucratic overhead and funder control between grants and gifts; see for more information.

Miscellaneous notes: Most GiveWell-recommended grants made by Good Ventures and listed in the Open Philanthropy Project database are not listed on Donations List Website as being under Open Philanthropy Project. Specifically, GiveWell Incubation Grants are not included (these are listed at with donor GiveWell Incubation Grants), and grants made by Good Ventures to GiveWell top and standout charities are also not included (these are listed at with donor Good Ventures/GiveWell top and standout charities). Grants to support GiveWell operations are not included here; they can be found at with donor "Good Ventures/GiveWell support".The investment in Impossible Foods is not included because it does not fit our criteria for a donation, and also because no amount was included. All other grants publicly disclosed by the Open Philanthropy Project that are not GiveWell Incubation Grants or GiveWell top and standout charity grants should be included. Grants disclosed by grantees but not yet disclosed by the Open Philanthropy Project are not included; some of them may be listed at

650,000.0012020-01Animal welfare/factory farming/meta/charity evaluator Hungerford Intended use of funds (category): Organizational general support

Intended use of funds: The grant page says: "ACE seeks to build a more effective farm animal welfare movement by identifying the most effective animal welfare charities and recommending them to donors."

Donor reason for selecting the donee: The grant page says: "Our farm animal welfare team believes ACE’s top charities are consistently effective, and finds value in pushing farm animal welfare organizations to focus on effectiveness and impact."

Donor reason for donating that amount (rather than a bigger or smaller amount): No specific reason for the amount is provided. The amount is almost double the previous 2-year grant made in April 2017; the increase might reflect increased budget of the donee or greater confidence in it from Open Phil.

Donor reason for donating at this time (rather than earlier or later): The timing is shortly after the end of the two-year time for the previous grant.
Intended funding timeframe in months: 24

Other notes: This is a total across two grants.
500,000.0022017-04Animal welfare/factory farming/meta/charity evaluator Bollard Intended use of funds (category): Organizational general support

Intended use of funds: The grant page section lists these proposed activities: increasing compensation (by $2,000 to $4,000 per year), adding staff time, hiring for two research positions, making small grants to evaluated charities (in the range of $500 to $1,000 per charity), intern stipends, and fundraising. The grant will increase ACE's expected revenue for 2017 from around $635,000 to $885,000. See also budget without Open Phil funding budget with Open Phil funding and plans for Open Phil funding

Donor reason for selecting the donee: gives these reasons: (1) Open Phil's version for the farm animal welfare movement in the next decade or two includes "an important role for an institution similar to a scaled-up version of ACE" (2) Open Phil expects that "the improvements ACE plans to make with this grant will allow it to direct more money to animal welfare groups that we consider highly effective, so we consider it fairly likely that this grant will achieve a roughly one-to-one return on investment in the near-term" (3) Open Phil hopes that the grant will help ACE address "what we view as some current shortcomings, including unsustainably low salaries, reliance on low-quality research, and undervaluing of long-term gainsx".

Donor reason for donating that amount (rather than a bigger or smaller amount): Amount likely determined based on budgets submitted by ACE and intended use of funds; see budget without Open Phil funding budget with Open Phil funding and plans for Open Phil funding

Donor retrospective of the donation: The followup grant and the continued endorsement on the grant page suggests that Open Phil would be satisfied with the success of the grant.

Other notes: See also on the ACE blog. It says "We feel that this grant is a reaffirmation of the value and impact of ACE’s work, and we are incredibly honored to have been selected." It says: "To those who may wonder if ACE will still be able to efficiently use additional donations, at this stage the answer is an emphatic yes." It links to fo the goals for 2017, and to for its 2017 fundraising. Intended funding timeframe in months: 24; announced: 2017-06-09.
