Human expertise as development input
Mercor connects professional experts with AI labs and enterprises for training and evaluation work. Its October 2025 Series C announcement describes that business and financing. The round’s valuation measures a financing outcome, rather than the quality of a particular dataset or the performance of a customer’s model. [1]
Different ways to measure an agent
Its current enterprise offering distinguishes expert staffing, production rubrics applied to live agents and offline APEX benchmarks in simulated tasks. These provide different evidence: observed production behavior, controlled comparisons and expert-authored criteria. The provider’s general claims do not establish an independent outcome for every model or customer. [2]
