Mercor Raises $750M at $20B Valuation to Expand AI Agent Evaluation to Enterprises

AI training data company Mercor has raised $750 million at a $20 billion valuation. The company supplies human domain experts, drawing on a network of more than 5 million, to train and evaluate AI models. Mercor is now pushing its agent evaluation offerings into enterprise markets after most of its work to date has been for AI labs.

Why it matters: The move signals that demand for expert-driven evaluation of AI agents is shifting from frontier labs toward enterprise buyers who need to test agents before deploying them.
