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, it was intended as an online directory of all Harvard's students to help residential students identify members of other residences. In June 2004, Zuckerberg, Hughes and Moskovitz took a year off from Harvard and moved Facebook's base of operations to Palo Alto, California, and hired eight employees. They were later joined by Sean Parker. At Facebook, Moskovitz was the company's first chief technology officer and then vice president of engineering; he led the technical staff and oversaw the major architecture of the site, as well as being responsible for the company’s mobile strategy and development. 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. 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 that Moskovitz's advice was important in persuading Morin to reject a $100 million offer for the company from Google, made in February 2011.
Philanthropy
Moskovitz co-founded the philanthropic organizationGood Ventures with his girlfriend Cari Tuna in 2011. In June 2012, Good Ventures announced a close partnership with charity evaluatorGiveWell. Both organizations "are aiming to do as much good as possible" and thereby align with the goals of effective altruism. Good Ventures has donated approximately $100 million from 2011 onward to GiveWell top charities Against Malaria Foundation, GiveDirectly, Schistosomiasis Control Initiative, and Deworm the World Initiative, as well as standout charities and other effective altruist organizations. The joint 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 to do the most good. The Open Philanthropy Project has since become a separate organization, and continuously increases its annual giving, having made over $170 million in grants in 2018 alone. Moskovitz and Tuna are also the youngest couple to sign Bill Gates and Warren Buffett’s Giving Pledge, which commits billionaires to giving away most of their wealth in the form of philanthropy.
Politics
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." 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. 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. 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." This made him the third-largest donor in the 2016 campaigns.
Personal life
Moskovitz is married to Cari Tuna. Tuna currently works full time on Good Ventures, the couple's private foundation, as well as the Open Philanthropy Project, a spinoff of a collaboration between Good Ventures and GiveWell. Tuna is a former Yale Daily News writer and journalist for The Wall Street Journal. Moskovitz and Tuna attend Burning Man regularly, and Moskovitz has written about his reasons for doing so. Moskovitz's attendance at Burning Man has been the subject of some press coverage.
Media depictions
Moskovitz is played in the film The Social Network by actor Joseph Mazzello. Responding to a question on Quora, Moskovitz said that the film "emphasizes things that didn't matter and leaves out things that we really did."
