Mercor

Mercor operates at the intersection of labour markets and AI research. The company partners with leading AI labs and enterprises to supply the human intelligence required to develop artificial intelligence, drawing on a network of domain experts who train frontier models by sharing knowledge, experience and context that cannot be captured in code alone. Its expert talent network comprises more than 30,000 specialists, who collectively earn over $1.5m per day.

The firm works across four technical domains: AI research, frontier AI model training, human data and expert feedback for AI, and labour market platforms. Its customer base spans AI research labs, artificial intelligence companies and enterprises, and it positions itself within the broader labour-markets and future-of-work sector. Mercor describes the work it enables as a new category in which expertise powers advances in AI.

Headquartered in San Francisco, Mercor raised a Series C round at a valuation of $10 billion and reports that it is profitable. The company works in-person five days a week from a new San Francisco headquarters, and describes its team as ambitious and fast-paced, working alongside researchers, operators and AI companies.
