micro1 is a data-labeling marketplace founded by 24-year-old Ali Ansari that uses an AI recruitment assistant to source and vet domain experts for RLHF, reasoning data, and robotics training datasets. The company pivoted from AI recruiting in 2025 and grew from an $80M valuation to a $500M Series A in eight months as Scale AI's ties with OpenAI and Google DeepMind unwound.
