Mercor

Marketplace of human experts who create training and evaluation data for AI labs

Overview

Mercor recruits domain experts, such as lawyers, doctors and engineers, to produce training data and evaluations for AI developers, and is expanding into evaluation and enterprise agent infrastructure. On 10 November 2026 it announced a US$750 million Series D at a US$20 billion valuation, with participation from Benchmark, Felicis, NVIDIA, Salesforce and General Catalyst; the company says it spends three times as much on inference as on employee salaries[46]. Its earlier Series C valued it at US$10 billion[46]. The company lists San Francisco in its site footer and has opened offices in New York and London[46]. Mercor has not published revenue. Its business depends on a small number of model developers whose data needs can change quickly.
