Micro1, a four-year-old AI data startup, has grown its gross annual revenue run rate from $100 million to $500 million in eight months, according to a person familiar with the company. Retaining roughly 60% to 70% of gross revenue, its net run rate sits between $150 million and $200 million.
The startup hires domain experts such as doctors, lawyers and scientists on contract to create and evaluate training data for AI labs and corporations, work that has exploded as model makers hunt for unique data. It began life as an AI recruiting company before founder Ali Ansari pivoted into data labeling after clients kept using the platform to vet annotation engineers.
Micro1 still trails rivals Mercor and Handshake, which passed $2 billion and $1 billion in gross annualized revenue respectively, but its growth shows demand can support multiple players. The company is also pushing into synthetic data, generating automated descriptions of video content without human involvement, and says selling the same off-the-shelf datasets to several customers can yield gross margins of 80% to 90%.
That practice has drawn controversy, with critics arguing that distributing data widely helps Chinese developers close the gap with US models. Ansari said last month that Micro1 does not sell to Chinese model makers, calling it shameful for US companies to claim AI dominance while selling data to adversarial nations.
Micro1 raised its Series A at a $500 million valuation last September and may have recently closed a larger round, TechCrunch reported.
