micro1 passes a $1B run rate with about 180 staff, three years after nearly going bust

What's going on? micro1 founder and CEO Ali Ansari says the AI training-data company has passed a $1 billion annual run rate while remaining profitable. About three years ago, he wrote, micro1 lost 60% of its revenue overnight and almost went bankrupt. The company says it crossed $500 million this summer; early investor Joshua Browder says it was at $700 million just weeks ago.

The unusual part: Ansari framed the milestone around eight operating principles rather than growth tactics. micro1's core team is only about 180 people across 14+ countries, fully remote, and he says hiring will slow significantly from here. He rejects 996-style rules and forced weekend work in favour of outsized incentives, says the company refuses to work with adversarial nations ("U.S. first"), and plans to keep a deliberately streamlined board.

Why it matters: At roughly 180 core staff, a $1B run rate works out to more than $5M per employee, a rare ratio even in AI. It is also a signal that expert human data, from medicine to law and engineering, has become one of the most lucrative layers of the AI stack alongside chips and power. Ansari confirmed micro1 priced its Series B at a $4B valuation after passing $500M, alongside a ~$25M tender for early employees, led by Dream Ventures with Microsoft, Javelin, Flybridge, G Squared, Up Partners and LG.

The caveats: The figures are company-reported and unaudited. micro1 did not say whether the $1B is gross bookings or net revenue; its earlier $500M milestone was reported as a gross run rate, which includes payments passed through to the tens of thousands of experts working on its platform.
