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 by Sean 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 called Asana with Justin 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. Moskowitz 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 a direct listing.[17]
The collaboration with GiveWell led to a spinoff called the Open 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.[22][23][24] 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.[25] Moskowitz is a supporter of using rationality to guide his decision-making.[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 sign Bill Gates and Warren Buffett's Giving Pledge, which commits billionaires to give away most of their wealth in the form of philanthropy.[28] Dustin is also a signatory of The Giving What We Can Pledge.[29]
Moskovitz has voted for the Democratic 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 to Sean Eldridge, the husband of Facebook co-founder Chris Hughes.[31]
Moskovitz, through his support of Open Philanthropy, has contributed to California YIMBY. 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 the 2016 United States presidential election, Moskovitz announced that he and his wife would donate $20 million to support Hillary Clinton, the Democratic Party nominee, arguing that the dangers of a Donald Trump presidency are 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 the 2020 United States presidential election, Moskovitz donated $24 million to support the Democratic Party nominee Joe 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 after Bloomberg LP.
Moskovitz was also the biggest angel investor in the mobile photo-sharing site Path, run by another former member of Facebook, David Morin. It was reported[37] that Moskovitz's advice was important in persuading Morin to reject a $100 million offer for the company from Google, made in February 2011.[38] In 2020, Moskovitz led a $40 million dollar Series D funding round for fusion power start-up Helion Energy.[39]
Moskovitz is played in the movie The Social Network by actor Joseph Mazzello. Responding to a question on Quora, Moskovitz said that the film "emphasizes things that didn't matter (like the Winklevoss 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)."[45]
