About Mercor
Mercor is a venture-backed expert-marketplace and AI-training-data company that organizes a network of ~30,000+ domain experts (doctors, lawyers, bankers, engineers) to produce RLHF data, evaluations, and reinforcement-learning environments for frontier AI labs and enterprises. Originally an AI-recruiting platform, it pivoted to human-data/RL services and expanded its RL-environment capability through acquisitions, including the February 2026 acquisition of Sepal AI and the July 2026 acquisition of Deeptune, whose computer-use/enterprise environment platform and NYC team joined Mercor.
