In a remarkable display of entrepreneurial success, three individuals have achieved self-made billionaire status at the young age of 22. Brendan Foody, Adarsh Hiremath, and Surya Midha are the minds behind Mercor, an artificial intelligence recruiting startup founded in 2023.

The journey for these young entrepreneurs began in their dorm rooms at Harvard and Georgetown.
