What happened
TechCrunch reported on 27 October 2025 that Mercor had raised a $350 million Series C led by Felicis Ventures, with Benchmark, General Catalyst and, as a new investor, Robinhood Ventures taking part. The round valued the company at $10 billion, against $2 billion at its Series B in February 2025.
Three days later, on 30 October, Forbes reported the consequence under a headline that stated it flatly: these 22-year-olds are now the world's youngest self-made billionaires. Foody, as chief executive and a co-founder, was among them. His Forbes profile later listed his net worth at $2.2 billion.
What Mercor actually does
The business sits at an unglamorous junction of the artificial-intelligence boom. Laboratories training large models need specialists, physicians, lawyers, scientists, to produce and evaluate material in their fields. Mercor recruits and matches those experts, charging hourly finder's fees and matching rates.
TechCrunch reported the scale at the time of the round: more than 30,000 contractors, average earnings above $85 an hour, and over $1.5 million paid out daily, with the company saying it was on track for $500 million in annualised revenue. That is a labour marketplace rather than a model laboratory, which is why its economics scaled so quickly.
Three debate partners
The research record sets out the origin: Mercor was founded in 2023 by Foody with Adarsh Hiremath and Surya Midha, teammates from the debate programme at Bellarmine College Prep. Foody dropped out of Georgetown University and became a Thiel Fellow, the programme that pays young founders to leave university.
Competitive debate is not an accidental background for this company. It trains people to research an unfamiliar domain quickly, argue it under pressure and be judged on the result, which is close to the exercise of evaluating expert work at speed.
How rare this is
Self-made billionaires in their early twenties are vanishingly rare, which is why Forbes treated the Mercor round as a list story rather than a funding story. The valuation is also a paper figure: it reflects what investors paid for a slice of the company in a single transaction, not cash in anyone's account.
Forbes's own profile, which put Foody's net worth at $2.2 billion, illustrates the point. Wealth calculated from a private company's most recent round moves with the next round, and in a sector where valuations have re-rated repeatedly it can move in either direction.
What is documented, and what is not
Firmly established: the $350 million Series C led by Felicis Ventures at a $10 billion valuation in October 2025, the previous $2 billion valuation in February 2025, the contractor numbers and payout rate, and the Forbes listing of the founders as the world's youngest self-made billionaires at 22.
Not established here: his date of birth, his role in the founding beyond the chief executive title, and how the company has performed since the round. The research record gives a birth year of 2003, consistent with being 22 in October 2025, and notes that Wikipedia's coverage attaches to Mercor rather than to him.
