Micro1 Raises $35M at $500M Valuation to Supply Vetted AI Training Contractors
Micro1 raised $35M at a $500M valuation to supply vetted human contractors for AI training. Led by O1 Advisors, the three‑year‑old startup — led by 24‑year‑old CEO Ali Ansari — says ARR jumped to $50M in 2025. Micro1’s AI recruiter 'Zara' vets expert labelers and the company is expanding into simulated training environments as labs diversify away from Scale AI.
