From Hackathon to $10 Billion: How Mercor Is Rewriting the Future of AI and Work

A new company is betting that the key to unlocking artificial intelligence’s full potential lies not in replacing humans, but in harnessing their uniquely human skills. Mercor,founded by a college dropout and his high school friends,has rapidly ascended to a $10 billion valuation by building a marketplace where professionals train AI systems,reshaping the landscape of both labor and technological advancement.
The Dropout and the São Paulo Spark
the story began in the spring of 2023,when Brendan Foody,while his peers at Georgetown University prepared for final exams,was already pursuing a different path. “I knew I wanted to drop out before finals my sophomore year,” he told Fortune. “I just didn’t go to finals.” Foody had already identified a gap between conventional education and real-world opportunity. That opportunity materialized at a hackathon in São Paulo,Brazil,where he and co-founders Adarsh Hiremath and Surya Midha conceived of a simple yet powerful model: connecting companies with skilled engineers abroad,managing the logistical complexities,and retaining a service fee. Their initial success – securing a $500-per-week contract for a developer, with 70% going to the engineer – proved the viability of their concept.
From Talent Marketplace to AI Trainer
What started as a talent-matching service quickly evolved into something far more ambitious. Mercor pivoted to become a platform where humans could directly contribute to the progress of AI, specifically by training the systems that may one day automate their own roles.The company now employs professionals – including consultants, lawyers, bankers, and doctors – to create detailed “evals” and rubrics designed to test and refine AI models’ reasoning abilities.
“Everyone’s been focused on what models can do,” a company spokesperson stated. “But the real opportunity is teaching them what only humans no-judgment, nuance, and taste.” Within nine months of this shift, the team had achieved a $1 million revenue run rate, demonstrating the potential of their approach. This early traction wasn’t accidental, but rather a reflection of the structured reasoning skills honed during their days on the high school debate circuit.
A Billion-Dollar Bet on Human-in-the-Loop Automation
Two years later, Mercor’s trajectory has been nothing short of meteoric. The company’s $10 billion valuation has transformed Foody, Hiremath, and Midha into the world’s youngest self-made billionaires. Investors view mercor as a critical component of the future of “human-in-the-loop” automation, a process that combines the power of AI with the irreplaceable expertise of human evaluators.
Investors are drawn to Mercor’s position at the intersection of two major trends: the widespread adoption of AI and the growing demand for flexible, project-based work. The company’s business model creates a powerful flywheel effect – each new client adds evaluators,and each evaluator contributes to refining the AI models,driving further demand. “We have one of the fastest revenue ramps of any company in history,” Foody stated matter-of-factly.
Addressing the Fears of Automation
Foody acknowledges the anxieties surrounding AI-driven job displacement, but argues for a pragmatic approach. “It’s easy to fall into a Luddite mindset and see productivity gains as bad because they cause short-term job losses,” he said.”But every major technical revolution has ultimately made life better.” He points to the industrial revolution, which transformed the American economy from 75% agricultural to less than 1%, freeing up labor for new industries and opportunities.
“The challenge now is to be thoughtful about what comes next: the higher, better things humans will spend time on,” Foody concluded, “and how quickly we can help make that future real.”
