Dustin Moskovitz, the millennial Meta co-founder who helped launch Facebook in 2004, and his wife Cari Tuna are on a mission to give away their $20 billion fortune as fast as possible, Fortune reported. The couple has already donated more than $4 billion, including $600 million this year, and placed another $10 billion into their foundation, Good Ventures, to fund global health, pandemic preparedness, and AI safety.

Moskovitz, 41, built Facebook alongside Mark Zuckerberg before founding Asana in 2008, now valued at $3 billion. His net worth stands at $10 billion. Tuna, 40, a former Wall Street Journal reporter, turned Moskovitz’s philanthropic vision into action, cofounding Good Ventures in 2011 and chairing its operations.

The Giving Pledge and effective altruism

The couple signed The Giving Pledge in 2010, with Tuna becoming its youngest signatory at 25. Their commitment: donate at least half their wealth during their lifetimes. “We will donate and invest with both urgency and mindfulness, aiming to foster a safer, healthier and more economically empowered global community,” Moskovitz wrote at the time.

Speaking to Forbes recently, Tuna said, “With hundreds of billions of dollars going into making AI more capable, there is immense competitive pressure to push the technology forward as quickly as possible. But in order to manage the risks, you need coordination across companies and across countries … as the pace of AI development continues to accelerate, we think it might be hard for society and institutions to keep up.”

Most of their giving follows effective altruism principles—using data to maximize impact per dollar.

Major grants and global impact
Through Open Philanthropy, which grew out of Good Ventures, Tuna has directed hundreds of millions toward high-impact causes:

$300 million to Malaria Consortium
$200 million to Evidence Action
$100 million to Helen Keller International

They’ve also backed pandemic prevention and AI safety long before COVID-19 or ChatGPT, donating $1 million to the Future of Life Institute, $30 million to OpenAI’s nonprofit arm, and moving a $500 million stake in Anthropic into a nonprofit vehicle, Fortune reported.

New collaborations

Recently, they helped launch the $100 million Lead Exposure Action Fund with the Gates Foundation and introduced the $120 million Abundance & Growth Fund alongside Stripe cofounder Patrick Collison to accelerate scientific progress.
