Dustin Moskovitz co-founded Facebook with Mark Zuckerberg and others in 2004, then left in 2008 to co-found the work-management software company Asana with Justin Rosenstein. His early Facebook stake made him a billionaire in his twenties, and he remains the largest shareholder of Asana, where he stepped back from the CEO role in 2025 to become executive chair.
Moskovitz's wider power lies in money directed outside his companies. With his wife, journalist Cari Tuna, he created the foundation Good Ventures and helped build the grantmaking organization Open Philanthropy, renamed Coefficient Giving in November 2025. Together they became the youngest couple to sign the Giving Pledge, and the operation has directed more than $4 billion in grants across global health, pandemic preparedness, scientific research, farm-animal welfare, and risks from advanced AI, making it the central financial engine of the effective-altruism movement.
He is also one of the most significant individual donors to the Democratic Party. Moskovitz emerged as a top funder of pro-Democratic groups such as the Future Forward PAC in 2020 and again in 2024, when he backed Vice President Kamala Harris's campaign. The combination of large-scale partisan giving and outsized philanthropic influence over the AI-policy debate gives one private fortune unusual reach into both elections and emerging technology governance.

Controversies
Donor influence over AI policy · 2023-2025
Open Philanthropy / Coefficient Giving's extensive funding of AI-safety institutes, think tanks, and congressional policy fellowships has drawn reporting that a single donor network shapes who advises lawmakers on artificial-intelligence regulation.
Scale of individual political spending · 2020-2024
His tens of millions in donations to pro-Democratic super PACs make him one of a small number of megadonors whose giving illustrates the concentration of campaign finance among the ultra-wealthy.
Effective-altruism movement turmoil · 2022-2023
As the dominant funder of effective altruism, his philanthropy was tied to scrutiny of the movement after the 2022 collapse of FTX, whose founder had been a prominent effective-altruism figure, prompting debate over the movement's governance and influence.

Why this matters
When one tech fortune simultaneously bankrolls a large share of a single ideological movement, funds much of the independent research and policy advice shaping AI regulation, and ranks among the biggest donors to a major political party, the priorities of an unelected couple can quietly steer both elections and the rules for a transformative technology. The public rarely sees how those grant and donation decisions are made, yet they help determine which ideas and candidates gain a hearing.
