Mercor
Marketplace matching frontier labs with vetted domain experts — doctors, lawyers, scientists, engineers — to produce and evaluate model-training data.
Mercor is a San Francisco company that began as an AI-powered hiring marketplace and pivoted to supplying frontier labs with vetted domain experts — doctors, lawyers, scientists and engineers — to produce and evaluate training data. Founded in 2023 by Brendan Foody, Adarsh Hiremath and Surya Midha, who met on a high-school debate team, it raised a $350m Series C at a $10bn valuation in October 2025, and reporting in 2026 said it was in talks to raise again at around $20bn. It grew quickly as some labs moved data work away from Scale AI following Meta's investment in that company.
