Dustin Moskovitz

Dustin Aaron Moskovitz (/ˈmɒskəvɪts/; born May 22, 1984) is an American internet entrepreneur who co-founded the social media service Facebook and its parent company Meta Platforms with Mark Zuckerberg, Eduardo Saverin, Andrew McCollum and Chris Hughes. In 2008, he left Facebook to co-found Asana with Justin 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. According to Forbes, as of May 2025, Moskovitz's estimated net worth stood at US$17.4 billion, making him the 125th richest individual in the world.

Moskovitz, who is Jewish, was born on May 22, 1984, in Gainesville, Florida, and grew up in Ocala, Florida. He attended Vanguard High School, graduating from the IB Diploma Program. Moskovitz attended Harvard University as an economics major for two years before he moved with Mark Zuckerberg to Palo Alto, California, in order to work full-time on Facebook.

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, 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.

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. In September 2020, Asana went public at a market value of about $5.5 billion in a direct listing.

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. Around that time, he held a 53% stake in the company.

Moskovitz co-founded the philanthropic organization Good Ventures with his girlfriend (and now wife) Cari Tuna in 2011. In June 2012, Good Ventures announced a close partnership with charity evaluator GiveWell. 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 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. 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. 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.

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. Dustin is also a signatory of The Giving What We Can Pledge.
