What Mercor does
Mercor is a private AI services and “expert labor network” company that connects domain professionals with AI labs and enterprises that need specialized human judgment to train, evaluate, and improve frontier models. The company’s core offering is a marketplace-like platform where companies describe the kind of expertise they need and Mercor matches and staffs vetted experts; experts then perform remote AI training/evaluation work (e.g., reviewing model outputs, creating examples, and scoring quality against expert standards).
