Mercor

What Mercor does

Mercor is an AI-native labor marketplace that aims to connect human domain expertise with frontier AI labs and enterprises that deploy AI in production. The company positions its platform as (1) a vetted expert network for “real work,” (2) AI-driven matching and recruiting workflows that reduce hiring friction, and (3) evaluation infrastructure that measures AI performance on economically valuable tasks.

For the “Experts” side, Mercor describes a workflow where domain experts are found, vetted, and paid for work through the Mercor network; it also promotes referrals and placement via its referrals experience. For the “Enterprise” side, Mercor markets an Enterprise AI capability that converts an organization’s real workflows/context into agent behavior and then continuously measures outputs against desired quality, aiming to reduce the “guesswork loop” that can stall agent deployments.

On the evaluation/research side, Mercor publishes APEX (the AI Productivity Index) benchmarks intended to measure whether frontier models can perform high-value, real professional work. It has added specific benchmark tracks such as APEX-Agents and expanded the APEX evaluation set over time.

Strategically, Mercor has moved from hiring/recruiting automation toward a broader “human intelligence infrastructure” spanning workforce matching, enterprise agent enablement, and benchmarks for model capability in real work environments—supported by a large and growing expert network and multiple rounds of institutional venture funding.
