Moskovitz is a co-founder of Facebook, the world’s largest social-networking company, and its biggest individual shareholder after Mark Zuckerberg. Moskovitz left Facebook in 2008 to launch Asana, an enterprise project management tool. Still, he owes most of his wealth to an estimated 3% stake in Facebook, where he has an agreement that allows Zuckerberg to vote his shares. His real time net worth is estimated at $14.8 billion as of February 2018, by Forbes.

Moskovitz was born in Gainesville, Florida and grew up in Ocala, Florida. He is eight days younger than Zuckerberg. Moskovitz is Jewish. His father was a psychiatrist and mother a teacher and an artist. 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. Moskovitz is married to former Wall Street Journal reporter Cari Tuna.

  • He is the great grandson of immigrants from Russia and Poland, and opposed Trump in the 2016 election.

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 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. As of 2016, the Open Philanthropy Project is in the process of becoming a separate organization, but it has already made over $40 million in grants.

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.
