Three 22-year-old high school friends are now the world's youngest self-made billionaires, according to Forbes. Their San Francisco-based artificial intelligence hiring startup, Mercor, recently raised $350 million in funding led by Felicis Ventures, valuing the company at $10 billion.
Forbes estimates that each founder — Brendan Foody, Adarsh Hiremath, and Surya Midha — holds roughly 22% of the company, making their personal fortunes soar past the billion-dollar mark all before their 23rd birthday.
