Mercor
Mercor is a human resource marketplace that connects domain experts with AI labs and enterprises for model training, evaluation, and production agent work. Doctors, lawyers, engineers, and operators apply once, pass a role-specific AI interview, and get matched to remote contract projects where they review model outputs, create training examples, and grade agent performance. The platform lists 396,400 roles created, an average contracted rate of $109 per hour, and more than $4 million in daily expert payouts.
Where generic crowd platforms pay flat rates for low-skill labeling, Mercor vets expertise before placement and structures pay around project complexity and domain depth. The same expert network powers frontier data for the top five AI labs and six of the Mag 7, runs the APEX benchmark family across 480 professional tasks, and supplies license-ready datasets with 50,000-plus expert-written tasks across 30 domains.
Enterprise teams book diagnostics, agent deployment, and production optimization through Mercor Enterprise AI, with engagements spanning incident response, invoice reconciliation, and workflow discovery. Founded in 2023 and headquartered in San Francisco, Mercor also publishes public APEX leaderboards that measure whether frontier models can complete real professional work in law, accounting, and software engineering.
