The world of tech startups is famously fast-paced, but every so often, a story emerges that resets the bar entirely. Enter Mercor, a breakout artificial intelligence recruitment company based in San Francisco, responsible for making three twenty-two-year-olds the youngest self-made billionaires on the planet. These childhood friends—Brendan Foody, Adarsh Hiremath, and Surya Midha—have captured the attention of Silicon Valley and beyond. Their meteoric rise is not just a lesson in entrepreneurship, but a glimpse into the evolving face of the AI industry.
Mercor: The Billion-Dollar Brainchild Born from Debate Club
Mercor wasn’t born in a boardroom; it started with three high school friends from the Bay Area, all passionate debate teammates. Foody, Hiremath, and Midha possessed not just academic chops but bold dreams. In 2023, their vision took shape: create a platform connecting top engineering talent from India with U.S.-based companies seeking freelance programmers.
Little did they know they would soon shift the recruitment paradigm for leading artificial intelligence labs in Silicon Valley and globally.
Breaking Records With a Landmark Investment
Earlier this week, Mercor announced a stunning $350 million funding round, led by Felicis Ventures and joined by heavy hitters like Benchmark, General Catalyst, and Robinhood. This round propelled Mercor’s company valuation to $10 billion, instantly elevating its trio of founders into the billionaire stratosphere. According to Forbes, each founder now holds an estimated 22% stake in the company.
“It’s definitely wild,” Foody told Forbes. “It feels surreal—beyond anything we could have imagined two years ago.”
Trailblazing: Younger Than Zuckerberg, Self-Made in AI
Even by the breakneck standards of Silicon Valley, Mercor’s founders stand out for their youth. All three are Thiel Fellows, recipients of a $100,000 grant from billionaire investor Peter Thiel’s program for young people willing to forgo college and pursue entrepreneurship. As the new vanguard of AI-era founders, they exemplify a bold, hands-on approach, and a willingness to leap before the safety net appears.
“If I weren’t building Mercor, I’d have just graduated from college a few months ago,” says Hiremath, who left Harvard as a sophomore. “Life has flipped upside down in a very short time.”
Outpacing Previous Young Billionaires
- Shayne Coplan, former youngest at 27, briefly held the “youngest self-made tech billionaire” title after his company, Polymarket, received a $2 billion investment.
- Alexandr Wang (Scale AI CEO) took the crown at 28, and his co-founder Lucy Guo became the world’s youngest self-made female billionaire at 30—outpacing even Taylor Swift.
- The Mercor founders, all 22, are younger than Mark Zuckerberg, who broke the billion-dollar mark at 23.
- Only Kylie Jenner reached self-made billionaire status earlier (at 21), though Forbes later revised her net worth due to questions over Kylie Cosmetics revenue reporting.
How Mercor Changed the Game in AI Talent and Data Labeling
Initially, Mercor focused on matching software engineers in India with U.S. firms. Their platform quickly evolved using AI-generated avatars for interviews, allowing job seekers to interact with companies looking for cutting-edge talent.
Soon, they realized a major business opportunity in the exploding market for data labeling—the backbone of generative AI. Mercor began connecting highly skilled professionals, such as doctors and lawyers, with leading research labs powering the AI revolution, including OpenAI. Their impact led to a spot on the Forbes Under 30 list for 2025.
In September, following their debut on the Forbes Cloud 100 list of top private cloud companies, Foody announced that Mercor had reached $500 million in annualized revenue—a fivefold leap in just six months.
The Rapidly Shifting World of AI Data: New Money, New Competition
The AI data labeling market has transformed practically overnight. In June, Meta bought a 49% stake in Scale AI for $14 billion, moving its superstar CEO, Alexandr Wang, under their wing. This massive deal lit a fire under other competitors, driving them to get more aggressive—especially as many high-profile AI labs are reluctant to partner with firms so closely tied to Meta and its ambitions.
Other contenders remain strong:
- Surge, founded in 2016, is rumored to be raising funds at a $30 billion valuation.
- Turing AI recently closed a $110 million round, hitting a $2.2 billion valuation.
- Invisible, valued at $500 million in 2023, has become a significant partner to OpenAI and Microsoft.
But with high stakes come high tensions. In September, Scale sued Mercor, accusing it of stealing trade secrets—citing hundreds of confidential documents allegedly transferred by a former Scale executive who joined Mercor. Yet Foody seems unfazed: “We don’t spend much time thinking about it,” he told Forbes.
Who Are These Extraordinary Founders?
Foody, Hiremath, and Midha aren’t just outliers in age—they’re true products of the Bay Area tech ecosystem, each the child of software engineers. Foody’s mother worked in real estate at Meta, while his father, who founded an early graphical interface company in the 1990s, now consults for startups. At 16, Foody launched a service helping friends secure Amazon Web Services promotions, charging $500 a pop.
Hiremath’s early curiosity about labor markets blossomed while researching at Harvard for former Treasury Secretary Larry Summers, now on OpenAI’s board—who later invested in Mercor. Hiremath and Midha have been friends since age 10, meeting at debate tournaments before connecting with Foody in high school.
Despite their new billionaire status, the founders insist their lives haven’t changed in flashy ways. “Most nights I leave the office at 10:30 PM, six days a week,” says Foody. “There really isn’t much time for distractions outside of work.”
Key Takeaways: Lessons from Mercor’s Meteoric Rise
Here’s what sets the Mercor founders apart:
- Youth isn’t a barrier: At 22, they’re younger than most past billionaire founders, even topping Mark Zuckerberg.
- AI’s recruiting needs are booming: By focusing on data labeling, Mercor found a lucrative niche powering the biggest breakthroughs in the field.
- Bold funding moves: Their $350 million raise and $10 billion valuation show that investors are betting big on emerging AI infrastructure.
- Silicon Valley’s spirit endures: Their story proves that the region still fosters tech’s boldest upstarts—and rewards those willing to take risks early.
- Controversies are part of the climb: In a hyper-competitive space, lawsuits and trade secret disputes are almost inevitable.
The Future: Will You Be the Next Legend?
The story of Mercor’s founders illustrates that ambition, speed, and a willingness to break the mold remain the calling cards of America’s startup scene. As AI continues to reshape our world, there’s never been a better time to think big—and act even bigger.
