Mercor went from $1M to $3B in run rate in 27 months.

Mercor's run rate since the seed, with every round

On Tuesday it raised $750M at a $20B valuation, double the price of a year ago:

  • 5 million experts in its network, paid more than $5M a day

  • $500K burned in its entire life, profitable ever since

  • zero salespeople for most of its growth

  • three founders aged 23, the youngest self-made billionaires in the world (according to Forbes)

What they do? An AI model improves when something tells it where it went wrong. In maths a calculator can check the answer. No tool can automatically check a banker's financial model or a lawyer's memo.

Mercor finds the bankers, lawyers and doctors, pays them to write real tasks and the rubrics that grade them, and sells those tests and practice environments to OpenAI and the other labs. Now it sells the same thing to the Fortune 500.

→ Mercor gets paid for every task that makes a model better at a real job.

📚 In this newsletter, I break down every phase from a college dev shop to $3B, with clips from the founders' own words and the takeaways for founders.
