Did 21-year-olds Build a Product That Leaves Recruiters Perplexed?

A Social Network on Steroids – A Story Like from a Movie

Three teenagers, instead of partying in dorms at prestigious universities, are building a $2 billion company from their rooms. Sounds like the script for another Hollywood hit about Facebook’s beginnings? This is the true story of Mercor – a startup that in just two years went from an idea to one of the most promising players in the HR Tech space.

Brendan Foody (CEO), Adarsh Hiremath (CTO), and Surya Midha (COO) – three high school friends and debate club partners – identified inefficiencies in traditional recruitment processes. Instead of continuing their education at Harvard and Georgetown, they bet everything on one card.

Interestingly, and consistent with the vision of Social Network 2.0, all three were selected for the Thiel Fellowship program in 2024, receiving a $100,000 grant and access to an elite network of tech entrepreneurs. Peter Thiel himself, PayPal co-founder and Facebook’s first external investor, created this program to encourage young visionaries to abandon studies in favor of building innovative companies. As Foody admitted, “the networking opportunities and support from the Thiel Fellowship helped him and his co-founders build the company faster.”

A Company of 22-year-olds Worth Billions

Mercor’s funding history might make your head spin:

• January 2023: Company founded and revenues developed to seven figures without external funding
• 2023: Raised $3.6 million in a seed round funded by General Catalyst
• 2024: $32 million Series A funding led by Benchmark. This gave Mercor a valuation of $250 million
• February 2025: Closed a $100 million Series B led by Felicis, with participation from Benchmark, General Catalyst, DST Global, and Menlo Ventures. Current valuation: $2 billion.

That’s an eightfold increase in valuation in just a few months! Even more impressive, according to Bloomberg’s report, the Series B funding round was organized in just two weeks, with investors approaching the company themselves, which is not common.

Despite the enormous valuation, Mercor maintains a relatively small team – about 75 people as of February 2025, with plans to expand to 100 by year-end. The company requires office work in San Francisco and openly talks about a 9-9-6 work schedule (9 AM to 9 PM, 6 days a week). Mercor also stands out for its extremely low median age of employees – around 22 years – making it one of the youngest teams operating at such scale in the tech industry.

A Game-Changing Product

Mercor’s main innovation lies in AI-powered recruitment infrastructure that brings unprecedented accuracy to the early stages of the recruitment funnel. The platform evolved from an initially human-led job matching service into an advanced AI-based system that:

• Automates CV screening and candidate matching
• Conducts 20-minute AI-driven video interviews that assess candidates’ skills and create detailed profiles
• Manages payroll and processes payments for hired candidates

Mercor’s AI technology creates an extensive profile of each candidate by analyzing resumes, GitHub repositories, personal websites, and other professional information. This allows employers to describe desired candidates in natural language and receive recommended matches within seconds.

What distinguishes Mercor is its focus on performance prediction. The platform collects data on candidate results to continuously refine its matching algorithms, improving recruitment outcomes over time. CEO Foody emphasized that Mercor’s models aim to better predict work performance compared to human recruiters.

Why Big Companies Choose Mercor

Mercor works with the largest AI labs, including all five leading ones, though only OpenAI is directly mentioned as a client. The company has dramatically expanded its candidate base, processing over 468,000 applicants with its technology. Mercor sources talent primarily from India, followed by the USA, while Europe and South America show rapid growth.

The company generates impressive revenues. At the beginning of 2025, the annual revenue rate was about $75 million. Unlike many AI startups, Mercor is profitable – according to Bloomberg, the company generated $1 million in profit on $7 million in revenue in February 2025 alone.

The business model generates revenue mainly through hourly fees for finding suitable candidates, charged to clients. With an annual revenue rate of $75 million and a $2 billion valuation, Mercor maintains a 27x ARR multiple, considered reasonable compared to other fast-growing AI startups that can achieve multiples up to 50x.

My Opinion – Will Mercor (and Similar Systems) Replace Recruiters?

As a recruiter, I look at companies like Mercor with mixed feelings. On one hand, the human aspect of recruitment – building relationships, intuitively sensing cultural fit, conversation nuances – is not easy to code, and therefore, recruiters still are/should be better at this.

Are we humans, with our innate biases, really the best “gatekeepers” for organizations? I often hear the argument that AI is biased because it learns from human data. That’s true, but perhaps it’s easier to fix biases in an algorithm that we know is imperfect than our own unconscious biases that block many talented people from accessing organizations?

When I read about Mercor’s success, I don’t see it as the end of the recruiter’s role, but rather a call to rethink how to use technology to eliminate unconscious biases and increase effectiveness. The future is not AI replacing recruiters, but recruiters enhanced by AI, who can devote more time to what humans are truly irreplaceable at – building authentic relationships and providing exceptional experiences to candidates. I don’t think many companies will hire someone without any human contact from the company. Therefore, I expect smaller recruitment teams rather than their complete disappearance.

Mercor and similar companies pose important questions – not just about how we recruit, but also about the future of work in an AI-driven economy. According to the vision of the company’s CEO Brendan Foody, as AI automates significant parts of the economy, human talent becomes a critical bottleneck for remaining tasks, creating enormous leverage for effective talent allocation.

The company predicts a shift toward more fractional, project-based work models, where specialists are engaged for specific projects rather than traditional full-time employment. This vision aligns with broader market trends toward the gig economy and remote work flexibility.

Whether you’re an AI enthusiast or an HR traditionalist, Mercor’s story forces us to reflect on our processes and biases. Perhaps this is the greatest value these young, innovative companies bring us – they force us to question the status quo and imagine new possibilities.
