Good Ventures is the private foundation of Facebook and [Asana](/organizations/asana/) cofounder [Dustin Moskovitz](/people/dustin-moskovitz/) and his wife [Cari Tuna](/people/cari-tuna/). When the couple became the youngest billionaires to sign the Giving Pledge, in 2010, he was a 26-year-old Harvard dropout who had made his fortune in four years at Facebook as its first chief technology officer, and she was a 25-year-old Yale graduate reporting for *[The Wall Street Journal](/organizations/the-wall-street-journal/)* on the California economy. With Moskovitz occupied with Asana, Tuna quit journalism to manage their giving, and they founded Good Ventures in 2011. Moskovitz's net worth was estimated at about 14.3 billion dollars at the end of 2017, and the couple said they intended to give away nearly all of it in their lifetimes; he said, "Cari and I are stewards of this capital. It's pooled up around us right now, but it belongs to the world."[^1]

### Filings and Officers

The Good Ventures Foundation, EIN 46-1008520, received its tax exemption in March 2013 and files its returns in care of Apercen Partners LLC at 314 Lytton Avenue, Palo Alto. The officers on every return since 2015 have been Tuna, president and later also board chair; Moskovitz, secretary and treasurer; and [Divesh Makan](/people/divesh-makan/), director, none of them paid; the 2025 return also lists Tom Van Loben Sels as assistant secretary.[^2] Makan is the sole member of the general partner of [ICONIQ Capital](/organizations/iconiq-capital/), the [San Francisco](/places/san-francisco/) investment firm.[^3]

### The Structure

In 2018 the *[Stanford Social Innovation Review](/organizations/stanford-social-innovation-review/)* writer [Marc Gunther](/people/marc-gunther/) counted seven entities in which Tuna served as a director or major donor: the Open Philanthropy Project LLC, which recommended grants; the [Open Philanthropy Action Fund](/organizations/open-philanthropy-action-fund/), a 501(c)(4) "that supports nonpartisan advocacy"; the Open Philanthropy Project fund, a donor-advised fund at the Silicon Valley Community Foundation; the Good Ventures Foundation, which made grants and investments; Good Ventures, a supporting organization also at the community foundation; Good Ventures LLC, "a for-profit impact investment firm"; and [GiveWell](/organizations/givewell/). [Alexander Berger](/people/alexander-berger/) of Open Philanthropy told him that "each has a reason for being" and that "tax considerations are key." Gunther wrote that grants made through the donor-advised funds "can't be traced back to the original donors," that the entities disclosed some but not all of their investments, and that Open Philanthropy did not disclose its operating costs or the pay of its highest-paid staff. Outside these structures, Moskovitz and Tuna were investors in [Bill Gates](/people/bill-gates/)'s Breakthrough Energy Ventures.[^1] The Open Philanthropy Action Fund has reported paying outside lobbyists every year from 2021 through 2026, Tarplin, Downs & Young and Arnold & Porter in 2021 and the Kyle House Group from 2023, on foreign relations, health and appropriations.[^4]

### GiveWell and Open Philanthropy

A friend introduced Tuna to [Holden Karnofsky](/people/holden-karnofsky/), who with [Elie Hassenfeld](/people/elie-hassenfeld/) had founded the charity evaluator GiveWell in 2007 after working at the hedge fund [Bridgewater Associates](/organizations/bridgewater-associates/). Tuna joined GiveWell's board in 2011. Good Ventures' first grant, of 50,000 dollars, went to GiveWell that year, with another 1.1 million dollars to GiveWell-recommended charities, chiefly the Against Malaria Foundation and the Schistosomiasis Control Initiative. By 2018 Good Ventures accounted for about 60 percent of the estimated 375 million dollars GiveWell had moved to its recommended charities. In 2012 GiveWell moved its office and staff of five from New York to San Francisco "to be closer to Tuna and other technology-industry donors."[^1] The joint project [GiveWell Labs](/organizations/open-philanthropy/), launched in 2012, was renamed the Open Philanthropy Project in August 2014 and spun off from GiveWell in June 2017, keeping overlapping boards and staff and shared offices.[^1][^5] Good Ventures gave 70.4 million dollars through GiveWell in 2015, 50.4 million in 2016 and 75.1 million in 2017.[^5]

Open Philanthropy, renamed Coefficient Giving in November 2025, draws nearly all of its grant money from Good Ventures.[^6] Its grantees include [OpenAI](/organizations/openai/), which received 30 million dollars in 2017 with a board seat for Karnofsky; the [Center for Security and Emerging Technology](/organizations/center-for-security-and-emerging-technology/); the [RAND Corporation](/organizations/rand-corporation/); the [Center for AI Safety](/organizations/center-for-ai-safety/); [Redwood Research](/organizations/redwood-research/); the [Horizon Institute for Public Service](/organizations/horizon-institute-for-public-service/), which pays technology fellows placed in Congress and federal agencies; and the [Tarbell Center for AI Journalism](/organizations/tarbell-center-for-ai-journalism/), which pays journalists placed in newsrooms.[^7] It had given away about 7 billion dollars by September 2026.[^8]

### Assets

The foundation's assets were 27 million dollars in the fiscal year ending June 2013, 1.02 billion in 2017, 3.34 billion in 2020, 5.86 billion in 2023 and 10.11 billion in 2025. Contributions received were 1.02 billion dollars in fiscal 2020, 1.91 billion in 2023, 801 million in 2024 and 1.40 billion in 2025, when it also reported 847 million dollars from sales of assets and paid 338 million dollars in charitable disbursements.[^2] In 2026 it held 1,720,916 Class A shares of Asana, the company Moskovitz controls; Asana's proxy statement said that Moskovitz and "his spouse serve as directors on the board of Good Ventures Foundation and may be deemed to have shared voting and dispositive power" over them. The same proxy disclosed that Asana bought 1.1 million dollars of AI services from [Anthropic](/organizations/anthropic/), in which Moskovitz "has a minority ownership interest."[^9] In April 2026 the *[Washington Examiner](/organizations/washington-examiner/)* reported that in 2025 Moskovitz had transferred his Anthropic stake, "which had reportedly grown to roughly $500 million, to his charity to avoid the appearance of conflicts of interests," without naming the entity.[^10]

### The Action Fund

The Open Philanthropy Action Fund, renamed Coefficient Giving Action Fund, EIN 81-2644663, is a 501(c)(4) that files in care of Apercen Partners at 314 Lytton Avenue, the foundation's own address. Tuna, Moskovitz and Makan have sat on its board on every return since 2017, with Van Loben Sels as treasurer, joined by Open Philanthropy's chief executives, Holden Karnofsky and Alexander Berger, and in 2017 and 2018 by Hassenfeld. It reported about 270.4 million dollars in contributions from 2016 to 2023, and liabilities greater than its assets at the end of each year from 2021 to 2023.[^11] On October 29, 2019, it gave 750,000 dollars to the non-contribution account of [Real Justice PAC](/organizations/real-justice-pac/), listing its address as 314 Lytton Avenue, Suite 200.[^12] Its lobbyists reported about 1.53 million dollars in income from it between 2021 and mid-2026.[^4]

### The Supporting Organization

A second tax-exempt entity named simply Good Ventures, EIN 45-2757586, files in care of the Silicon Valley Community Foundation at the community foundation's own headquarters, 2440 West El Camino Real, Suite 300, Mountain View. Its [Internal Revenue Service](/organizations/internal-revenue-service/) record classifies it as a 509(a)(3) supporting organization, and its tax exemption was ruled on September 1, 2012, six months before the Good Ventures Foundation's own exemption in March 2013. It received 79.3 million dollars in contributions in fiscal 2012, 80.1 million in 2013, 70.5 million in 2014, 174.6 million in 2015, 38.3 million in 2016 and 6.1 million in 2017. In fiscal 2017 its total expenses were 188.9 million dollars against revenue of 26.7 million, and its net assets fell from 262.0 million dollars at the end of fiscal 2016 to 99.4 million a year later. A return for the fiscal year ending October 2018 is listed without extracted data, and no later return appears in the index.[^13]

A document prepared for a GiveWell board meeting of June 17, 2015, stated: "The Silicon Valley Community Foundation provides some administrative support to Good Ventures including some support on grants made via OP. This is not included in Good Ventures' support of OP and GiveWell." It recorded that Tuna, as president of Good Ventures, sat on Open Philanthropy's leadership team with Elie Hassenfeld, Alexander Berger and "Howie," and decided whether to approve grants, and that Good Ventures had filed for the Open Philanthropy Project trademark and owned the openphilanthropy.org address.[^14] Open Philanthropy's grantmaking process page states that "The Open Philanthropy Project, LLC (the organization that employs most Open Philanthropy staff) generally does not pay grants directly, but instead submits formal recommendations to one of our external funding partners, such as the Silicon Valley Community Foundation or the Good Ventures Foundation, which then conducts legal due diligence and a formal approval process to determine whether or not to fund the grant."[^15]

Good Ventures LLC, which Gunther described as a for-profit impact investment firm, does not appear as a filer in the [Securities and Exchange Commission](/organizations/securities-and-exchange-commission/)'s company index, and no filing in the commission's full-text index names it together with Moskovitz.[^16] *Forbes* reported in 2025 that most of Good Ventures' impact investments were in drug development and that its largest holdings included Impossible Foods, its first impact investment, and the semiconductor and technology companies TSMC, ASML, Nvidia and Microsoft.[^17]
