Moskovitz is a co-founder of Meta Platforms, the company behind Facebook, the world's largest social network. The Menlo Park, California-based business reported revenue of $166 billion in 2024 and had about 3 billion monthly active users. Moskovitz also co-founded Asana, a provider of task management software which went public in 2020.
The largest part of Moskovitz's fortune is derived from his founding stake in Meta Platforms. Meta's Facebook, the world's largest social network, has about 3 billion monthly active users, according to a February 2024 company presentation.
Moskovitz had an 8.5% voting stake in Meta immediately following its IPO, according to a May 2012 S-1/A filing. Although he left the company in 2008, he continued to appear in Meta filings through 2023. In May 2025, his stake was removed because filings could no longer confirm his level of ownership, causing Bloomberg's valuation of his net worth to decrease by about $18 billion.
Moskovitz also founded task-management software company Asana with a former Meta colleague and owns about 123 million shares of Class A and B stock, according to the 2024 proxy statement and an April 2025 Form 4 filing.
Moskovitz' cash balance reflects his historical stock sales adjusted for taxes, dividends, market performance and charitable contributions, including to his foundation, Good Ventures.
Born in Gainesville, Florida, Moskovitz grew up in nearby Ocala, graduating from Vanguard High School in 2002. He enrolled at Harvard University, where he roomed with Mark Zuckerberg and Chris Hughes during their freshman year. With classmate Eduardo Saverin, the partners created Facebook from their dorm room in 2004. The site quickly migrated to other universities, prompting Moskovitz and Zuckerberg to drop out of Harvard University and move to Silicon Valley.
In the fall of 2004, Facebook received $500,000 in funding from venture capitalist Peter Thiel. Investments from other venture firms quickly followed. By December 2004, Facebook's membership was approaching 1 million users.
Moskovitz became Facebook's chief technology officer and, later, vice president of engineering. He left the social network in November 2008 to start Asana, an online company providing task management software, with Facebook colleague Justin Rosenstein. In December 2010, Moskovitz joined the Giving Pledge, committing to donate the majority of his fortune to charity. He started his foundation Good Ventures in 2011.
