Dustin Aaron Moskovitz[1] (/ˈmɒskəvɪts/; born May 22, 1984)[2] is an American internet entrepreneur who co-founded the social media serviceFacebook and its parent companyMeta Platforms withMark Zuckerberg,Eduardo Saverin,Andrew McCollum andChris Hughes.[3] In 2008, he left Facebook to co-foundAsana[4] withJustin Rosenstein. In March 2011,Forbes reported Moskovitz to be the youngest self-made billionaire in the world, on the basis of his then 2.34% share in Facebook.[5] According toForbes, as of May 2025, Moskovitz's estimated net worth stood at US$17.4 billion, making him the 125th richest individual in the world.[6]
Four people, three of whom were roommates—Mark Zuckerberg,Eduardo Saverin,Chris Hughes, and Dustin Moskovitz—founded Facebook in their Harvard University dorm room in February 2004. Originally called thefacebook.com,[12] it was intended as an online directory of all Harvard's students to help residential students identify members of other residences.[3][13] In June 2004, Zuckerberg, Hughes and Moskovitz took a year off from Harvard and moved Facebook's base of operations to Palo Alto, and hired eight employees.[14] They were later joined bySean Parker. At Facebook, Moskovitz was the company's first chief technology officer and then vice president of engineering.[15]
On October 3, 2008, Moskovitz announced that he was leaving Facebook to form a new company calledAsana withJustin Rosenstein, an engineering manager at Facebook. Asana's mission is to improve the efficiency of office workers, providing them with a tool to manage and track projects and tasks. Moskovitz has remained CEO, with Rosenstein now serving as board member and advisor.[16] In September 2020, Asana went public at a market value of about $5.5 billion in adirect listing.[17]
In March 2025, Moskovitz announced his intention to retire from the company and transition to a chairman role once the company's board finds a replacement CEO.[18] Around that time, he held a 53% stake in the company.[18]
The collaboration with GiveWell led to a spinoff called theOpen Philanthropy Project, whose goal is to figure out the best possible way to use large sums of money (starting with Moskovitz's multi-billion-dollar fortune) to do the best.[23][24][25] Renamed to just "Open Philanthropy", it has since become a separate organization, and continuously increases its annual giving, having made over $170 million in grants in 2018.[26] In 2023, Moskovitz through Open Philanthropy donated $900,000 to scientists in Africa, Asia, and South America to further study the impacts of climate change.[27]
Moskovitz and Tuna are also the youngest couple to signBill Gates andWarren Buffett'sGiving Pledge, which commits billionaires to give away most of their wealth in the form of philanthropy.[28] Dustin is also a signatory of TheGiving What We Can Pledge.[29]
Moskovitz has voted for theDemocratic Party candidates in each election in which he has voted, but he wrote: "Though we've voted for the Democratic nominee each of the times we've cast a ballot, we've considered ourselves independent thinkers who respect candidates and positions from both sides of the aisle."[30] Prior to their donation for the 2016 election cycle, Moskovitz and Tuna had donated roughly $10,000 over their lifetime to federal candidates, most of it toSean Eldridge, the husband of Facebook co-founderChris Hughes.[31]
Moskovitz, through his support of Open Philanthropy, has contributed to CaliforniaYIMBY. Open Philanthropy, mainly funded by Moskovitz and his wife, has donated around $500,000 to the cause.[32] Open Philanthropy also contributed $2 million to the New York City based YIMBY group Open New York.[33]
For the2016 United States presidential election, Moskovitz announced that he and his wife would donate $20 million to supportHillary Clinton, the Democratic Party nominee, arguing that the dangers of aDonald Trump presidency were significant, and that they were making their donation despite being skeptical of allowing large donors to influence election cycles through money.[34]The New York Times quoted Moskovitz's blog post on the subject: "The Republican Party, and Donald Trump in particular, is running on a zero-sum vision, stressing a false contest between their constituency and the rest of the world."[30][31] This made him the third-largest donor in the 2016 campaigns.[34]
For the2020 United States presidential election, Moskovitz donated $24 million to support the Democratic Party nomineeJoe Biden.[35] Asana's own listed contributions for the election cycle, which are almost all directly from Moskovitz and his wife Cari Tuna, reached around $45 million.[36] This makes Asana the second largest contributor to Biden's presidential campaign afterBloomberg LP.
Moskovitz was also the biggestangel investor in the mobile photo-sharing sitePath, run by another former member of Facebook, David Morin. It was reported[39] that Moskovitz's advice was important in persuading Morin to reject a $100 million offer for the company fromGoogle, made in February 2011.[40] In 2020, Moskovitz led a $40 million Series D funding round for fusion power start-upHelion Energy.[41]
Moskovitz is played in the movieThe Social Network by actorJoseph Mazzello. Responding to a question onQuora, Moskovitz said that the film "emphasizes things that didn't matter (like theWinklevoss brothers, whom I've still never even met and had no part in the work we did to create the site over the past 6 years) and leaves out things that did (like the many other people in our lives at the time, who supported us in innumerable ways)."[47]
