Mercor
AI-powered expert marketplace that supplies AI labs and tech companies with vetted professionals for model training, evaluation and hiring.
Mercor runs an AI-driven platform that sources, vets and pays domain experts, such as engineers, lawyers and consultants, for remote work. It started as an AI hiring platform and pivoted to data labeling and RLHF work for AI labs including OpenAI and Anthropic. It earns money by taking a cut, roughly 30–35%, of the spend routed to its contractors. It raised a $350M Series C at a $10B valuation in October 2025, and was reported in July 2026 to be in talks at about $20B. Sacra estimates it reached about $2B in annualized gross revenue in June 2026.
Valuation: $10B post-money, $350M Series C (Oct 2025, Felicis). In talks at $20B per Bloomberg/TechCrunch, Jul 2026.
