Six former college students have become the world’s youngest self‑made tech billionaires, proving that leaving university does not block a path to massive success in AI. Their journeys offer concrete steps for ambitious learners who aim to build AI‑focused startups.

Surya Midha, Brendan Foody and Adarsh Hiremath left Georgetown and Harvard in 2023 to co‑found the AI recruitment startup Mercor. In October 2025 the company raised $350 million at a $10 billion valuation, making each founder a billionaire at 22 with an estimated $2.2 billion fortune.

Mercor soon expanded beyond recruitment, supplying specialists who train AI models. By June 2025 its annualized gross revenue had surpassed $2 billion, showing rapid growth beyond its original market.

Fabian Hedin dropped out of KTH and co‑founded Lovable in 2023. The AI‑driven ‘vibe coding’ platform reached a $6.6 billion valuation in December 2025 and a $13.3 billion valuation in August 2025, with annualized revenue exceeding $600 million.

Shayne Coplan left NYU after his freshman year and launched the prediction‑market platform Polymarket in 2020. In October 2025 Intercontinental Exchange invested $2 billion at a $9 billion valuation, giving Coplan a $1 billion fortune at 27. Meanwhile, Alexandr Wang dropped out of MIT after his freshman year, co‑founded Scale AI, and regained billionaire status when Meta invested $14.3 billion for a 49 % stake in June 2025; he now leads Meta’s Superintelligence Lab.

These stories show that early focus on a clear AI problem, fast product development, and attracting large‑scale investment can turn a college dropout into a tech billionaire. The key lesson is that decisive action and scaling expertise can outweigh a traditional degree.
