Mark Zuckerberg became the youngest self-made billionaire back in 2012 when he took Facebook public. According to Forbes, he was just 23 years old at the time.
Now, at the age of 41, Zuckerberg has an estimated $209 billion net worth. But if you think that’s impressive, just wait until you hear about the trio of 22-year-olds who recently became self-made billionaires all on their own.
Meet the World’s Youngest Billionaires
Brendan Foody, Adarsh Hiremath and Surya Midha are the world’s youngest self-made billionaires at just 22 years old. They are the CEO, chief technology officer and chief operating officer (respectively) of an artificial intelligence (AI) recruiting startup, Mercor, which they launched back in 2023.
The path to billionaire status began when the trio started their business from their Harvard and Georgetown dorm rooms. In two short years, they managed to bring in seven figures annually and expand their reach to 25 different countries. By September 2025, Mercor had an annualized revenue run rate of $500 million.
The trio has also amassed hundreds of millions in funding for their company. In a funding round led by Felicis Ventures, they secured $350 million. That was in October 2025.
Mercor recently received a $10 billion valuation of their company, according to Forbes. Given each co-founder has roughly a 22% stake in the AI platform, that’s roughly $2.2 billion each.
