Dustin Moskovitz

Dustin Moskovitz (born May 22, 1984) is an American technology entrepreneur who cofounded Facebook with Mark Zuckerberg in 2004 and later cofounded the workplace-software company Asana. With his wife Cari Tuna he became the largest sustained funder of the Effective Altruism movement through Open Philanthropy and one of the largest Democratic political donors in the United States. His career traces the same Facebook fortune that made Peter Thiel, the company's first outside investor, a billionaire, and his philanthropy and politics run in the opposite direction from Thiel's.¹²

Facebook and Asana

Moskovitz was Zuckerberg's roommate at Harvard University and one of Facebook's founding team, serving as its first chief technology officer and head of engineering. He left in 2008 to cofound Asana with Justin Rosenstein, took the company public in 2020, and built a second fortune; his net worth, derived chiefly from his early Facebook stake, exceeds sixteen billion dollars. He stepped down as Asana chief executive in March 2025 while remaining chairman.¹³

Moskovitz retained roughly two percent of Facebook at its 2012 initial public offering, a stake worth several billion dollars that became the foundation of his wealth and his giving. Asana took its name from a yoga term and went public by direct listing on the New York Stock Exchange in September 2020. His March 2025 retirement announcement, in which he said he would transition out of the chief-executive role, was followed by a sharp drop in Asana's share price; he stayed on as board chair and remained the company's largest shareholder.¹³

Open Philanthropy and Effective Altruism

In 2011 Moskovitz and Tuna founded Good Ventures, and they later joined with the charity evaluator GiveWell to create Open Philanthropy, which became the principal sustained financier of effective altruism, longtermism, and AI-safety work, directing more than four billion dollars in grants. The funding flowed to the same AI-risk research community around the Machine Intelligence Research Institute and the Future of Humanity Institute that Eliezer Yudkowsky and Nick Bostrom built, and Open Philanthropy was an early backer of the AI company Anthropic. Moskovitz signed the Giving Pledge, committing the majority of his wealth.²⁴

Good Ventures supplies nearly all of Open Philanthropy's grantmaking, making the foundation's reach a direct function of Moskovitz and Tuna's fortune; the organization's own analysis acknowledged that the movement's funding base rests heavily on the couple. Open Philanthropy's 2017 grant of 30 million dollars to OpenAI came with a board seat for co-chief-executive Holden Karnofsky, an early instance of the foundation embedding itself inside an AI lab, and it later invested in Anthropic. Operating from November 2025 as Coefficient Giving, the organization began pooling money from outside donors so that other philanthropists could fund its cause areas alongside Good Ventures.²⁴

Political Giving

Moskovitz became one of the largest individual donors to Democratic causes, an explicit counterweight to right-wing megadonors. He and Tuna pledged roughly twenty million dollars to defeat Donald Trump and elect Hillary Clinton in 2016, and in 2020 he gave approximately ninety-two million dollars to the Democratic super PAC Future Forward, among the largest single contributions of the cycle, followed by further giving to the same vehicle in 2024. The pattern is the inverse of Thiel's funding of Trump, JD Vance, and the tech-right: two beneficiaries of the same company financing opposed political projects, while both poured money into the competing wings of the AI-risk debate.⁵⁶

In the 2024 cycle Moskovitz gave 38 million dollars to Future Forward, the main super PAC backing Kamala Harris, plus 929,600 dollars to the Biden Victory Fund, ranking among Harris's largest billionaire donors. The 2016 effort was bipartisan in intent: Moskovitz wrote that his roughly twenty-million-dollar commitment was meant to counter what he saw as the danger of a Trump presidency, the first time he and Tuna had given at that scale to electoral politics. He has framed his political spending in the same expected-value terms as his philanthropy, treating elections as high-stakes interventions on the same metric of marginal impact that governs Open Philanthropy's grants.⁵⁷
