The AI training startup, which supplies subject-matter experts to help train and test models, says it will use the money to train and evaluate AI agents on professional work.

Mercor said on Tuesday it raised $750 million in a Series D round that values the San Francisco company at $20 billion, Reuters reported. Benchmark, Felicis, Fundomo, Nvidia and funds managed by affiliates of Apollo were among the participants. Mercor began as an AI-powered hiring platform and now connects technology companies with subject-matter experts whose knowledge is used to train, test and improve AI models and agents. It said it will use the funding to help train and test AI agents on professional tasks. “Every job in the economy will need its own AI agents, and every company will need a way to train and evaluate them on its own work,” co-chief executive Brendan Foody said. Reuters said Mercor was valued at about $10 billion after raising $350 million in October last year.
