Silicon Valley’s Youngest Billionaires: Three 22-Year-Old Entrepreneurs Hit Billionaire Status

The tech world just witnessed an extraordinary milestone. Three friends who once debated together in San Mateo County high school have achieved what seemed impossible. They’ve become the youngest self-made billionaires in history at just 22 years old.

These young entrepreneurs built something remarkable. Adarsh Hiremath, Surya Midha and Brendan Foody have become the world’s youngest self-made billionaires at just 22 years old. Their company, Mercor, has shattered records and expectations in Silicon Valley’s competitive landscape.

The Rise of Mercor: From College Dropouts to Billionaire Status

The trio co-founded Mercor, a Bay Area startup that helps Silicon Valley’s biggest artificial intelligence (AI) labs train their models by connecting them with thousands of skilled human experts across industries. What started as a recruiting platform has evolved into something much bigger.

Their journey began while they were still college students. The company, founded in 2021 while they were still in college, has become one of the fastest-growing players in the rapidly expanding “human-in-the-loop” AI sector — an industry that relies on human intelligence to refine machine learning models.

All three founders made a bold decision early on. All three founders are Thiel Fellows, members of conservative billionaire investor Peter Thiel’s program to dole out $100,000 grants every year to young people in exchange for foregoing college. They’ve become the poster children of the AI era’s twenty-something entrepreneurs.

The $10 Billion Valuation That Changed Everything

The numbers are staggering. According to Forbes, Mercor’s latest funding round has pushed its valuation to $10 billion, instantly minting the three former debate teammates from San Mateo County as billionaires.

Their most recent funding achievement speaks volumes about their success. Mercor, which connects AI labs with domain experts for training their foundational AI models, has raised $350 million at a $10 billion valuation, the company confirmed to TechCrunch. This represents an incredible leap from their previous valuation.

The growth trajectory is mind-blowing. Artificial intelligence hiring startup Mercor announced a $350 million Series C funding round, bringing its valuation to $10 billion. The funding marks a fivefold increase in valuation since its previous raise earlier this year.

How Mercor Generates Revenue and Builds Wealth

Understanding how these 22-year-old entrepreneurs generate such massive wealth requires looking at their business model. Mercor reportedly pays more than $1.5 million daily to its network of human contractors worldwide, making it one of the largest employers in the AI training space.

The scale of their operations is impressive. The startup says it currently pays more than $1.5 million per day to its contractors. It has more than 30,000 experts on its roster, who earn over $85 per hour on average.

Revenue flows through their unique approach to AI training. Mercor earns revenue by providing companies with specialized domain experts to perform AI model training — such as scientists, doctors, and lawyers — and charging an hourly finder’s fee and matching rate for their work.

The Perfect Storm: Timing and Competition

Sometimes success comes from unexpected advantages. The company was able to take advantage of the pivot to data-labeling after Meta paid $14.3 billion for a 49% stake in Scale AI in June. As part of the deal, founder and then CEO Alexandr Wang stepped down to join the social media company. Concerns over Scale AI’s neutrality following the Meta investment reportedly caused some large AI labs, including Google and OpenAI, to cut ties following the deal.

One of the founders described the situation bluntly. “It just doesn’t happen too often in startups where your biggest competitor gets torpedoed overnight,” cofounder Adarsh Hiremath told Forbes.

Their major clients include some of the biggest names in tech. The company claims to supply data labeling contractors to five top AI labs, including Amazon, Google, Meta, Microsoft, and OpenAI, as well as Nvidia. According to sources, an outsized portion of its revenue is coming from a subset of those brands, including OpenAI.

Personal Stakes and Individual Wealth

The three founders each hold significant equity positions. The new infusion of cash makes CEO Brendan Foody, CTO Adarsh Hiremath and board chairman Surya Midha the newest billionaires of the AI boom, each with a roughly 22% stake in the company, Forbes estimates.

Their personal transformation has been dramatic. One founder reflected on the rapid change in his life: “The thing that’s baffling for me is, if I weren’t working on Mercor, I would have just graduated college a couple months ago,” said Hiremath, who spent two years at Harvard before dropping out after Sophomore year.

What Makes These Entrepreneurs Special?

These youngest self-made billionaires represent something unique in Silicon Valley’s ecosystem. Even in youth-obsessed Silicon Valley, where neophyte founders have been lionized for decades, the startup is particularly well-known for the young age of its leaders.

The company culture reflects their youth. As for its own hiring, Mercor, with an average team age of 22, recently hired the former head of Human Data Operations at OpenAI and the previous head of Growth at Scale.

Comparing the New Generation with Previous Records

These new youngest self-made billionaires have surpassed previous records. While Wang is the world’s youngest self-made billionaire thanks to his artificial intelligence unicorn Scale AI, which raised $1 billion at a $13.8 billion valuation in May. Forbes estimates that he has a 14% stake in the company, which labels the data used to train the AI for large language models (including ChatGPT) and self-driving cars. He cofounded Scale, which now counts Microsoft, General Motors and Meta among its customers, with Lucy Guo in 2016, after dropping out of MIT following his freshman year. However, the Mercor trio has now claimed the title at an even younger age.

Most other young billionaires today inherited their wealth. These ultra-wealthy youth stand in stark contrast to the typical billionaire (average age mid-60s) and owe their fortunes largely to family legacies. For the first time in over a decade, every billionaire under 30 has inherited their wealth – a testament to how major “wealth transfer” events (like the passing of visionary founders and patriarchs) are minting young heirs.

The Business Model Behind Their Success

Mercor’s evolution tells an interesting story. Mercor started as a recruiting platform but pivoted to supplying specialized human expertise — from lawyers and doctors to engineers — to train and fine-tune artificial intelligence systems.

Their approach addresses a critical need in the AI industry. The company’s success mirrors a growing trend in the AI ecosystem, where young entrepreneurs are building fortunes not just by creating algorithms but by powering the human feedback loops that train them.

Looking forward, they have ambitious expansion plans. Mercor said it will focus on three areas: expanding its talent network, improving its systems for matching its contractors with clients, and building new products to automate more of its processes.

The Future Plans for These Young Billionaires

These 22-year-old entrepreneurs aren’t stopping at their current success. To further diversify its business model, Mercor has been telling investors that it is adding more software infrastructure for reinforcement learning — a training method where a model’s or agent’s decisions are verified or disputed, enabling it to incorporate feedback and improve over time. The company also intends to eventually build an AI-powered recruiting marketplace.

Their revenue trajectory suggests continued growth. Founded in 2022, Mercor is approaching $450 million in annualized run-rate revenue, one person said. The company told TechCrunch in February that its annual revenue (calculated by multiplying the latest month by 12) had reached $75 million at that time.

Lessons from Silicon Valley’s Youngest Self-Made Billionaires

What can other entrepreneurs learn from these youngest self-made billionaires? Several key factors contributed to their remarkable success:

Bold Decision-Making: Dropping out of college to accept Thiel Fellowship grants showed their commitment to entrepreneurship over traditional paths.

Market Timing: They entered the AI training market at the perfect moment when demand for human-in-the-loop AI was exploding.

Pivot Strategy: Their willingness to shift from recruiting to AI training services helped them capture a more lucrative market.

Strategic Partnerships: Building relationships with major AI companies like OpenAI and Google provided steady revenue streams.

Competitive Advantage: When their biggest competitor faced challenges, they capitalized on the opportunity quickly.

The Broader Impact on Entrepreneurship

The success of these youngest self-made billionaires sends powerful signals to aspiring entrepreneurs worldwide. At 22, the trio has joined a rarefied club — becoming, as Forbes notes, “the world’s youngest self-made billionaires,” marking a defining moment for Silicon Valley’s youth-driven AI revolution.

Their achievement challenges traditional business timelines. You don’t need decades of experience to build billion-dollar companies. With the right idea, timing, and execution, young entrepreneurs can achieve extraordinary success.

However, their story also highlights the importance of being in the right ecosystem. Silicon Valley provided access to funding, talent, and customers that enabled their rapid growth. The concentration of AI companies in the Bay Area gave them immediate access to potential clients.

What This Means for the AI Industry

The emergence of these 22-year-old billionaires reflects broader trends in artificial intelligence development. Companies increasingly recognize that human expertise remains crucial for training AI models effectively.

The “human-in-the-loop” approach that Mercor pioneered addresses fundamental limitations in pure machine learning. While AI can process vast amounts of data, human experts provide context, nuance, and judgment that algorithms still struggle to replicate.

This creates sustained demand for the services these youngest self-made billionaires provide. As AI becomes more sophisticated, the need for expert human input actually increases rather than decreases.

The Road Ahead

These three friends who became the youngest self-made billionaires face both opportunities and challenges ahead. Competition in the AI training space continues intensifying. New companies are entering the market, and existing players are expanding their services.

However, their early success has provided significant advantages. Strong relationships with major AI companies create barriers for competitors. Their substantial funding gives them resources to invest in technology and talent acquisition.

The story of these youngest self-made billionaires demonstrates that in today’s fast-moving tech landscape, age is becoming less relevant than execution ability. When you combine the right market opportunity with smart strategy and relentless execution, extraordinary outcomes become possible.

Their success also validates the power of friendship and shared vision in entrepreneurship. These three former debate teammates leveraged their existing relationship to build trust and make rapid decisions as they scaled their company.

Conclusion

The achievement of these youngest self-made billionaires marks a historic moment in entrepreneurship. Adarsh Hiremath, Surya Midha, and Brendan Foody have proven that with the right combination of timing, strategy, and execution, young entrepreneurs can build billion-dollar companies in remarkably short timeframes.

Their success with Mercor provides a template for future entrepreneurs: identify market gaps, be willing to pivot when necessary, and execute with speed and precision. Most importantly, they show that in the age of AI, human expertise remains invaluable.

As these three 22-year-olds continue building their company, they’re not just accumulating wealth – they’re reshaping how AI systems learn and improve. Their story will likely inspire countless other young entrepreneurs to pursue ambitious goals and challenge conventional wisdom about business success timelines.

The youngest self-made billionaires have set a new standard for entrepreneurial achievement. Their journey from college dropouts to billionaires in just a few years exemplifies the incredible opportunities available in today’s technology landscape for those bold enough to seize them.
