Mercor announced a $750 million Series D at a $20 billion valuation on November 10, as it expands its human-expert training and evaluation work into enterprise AI.
The company’s announcement says the round included an employee tender but does not disclose its size. The headline funding figure therefore should not be treated as a confirmed amount of new operating capital.
Mercor says it helps businesses assess AI agents against their actual workflows, including company-specific systems, policies and quality requirements. Those evaluations can identify where models need additional training or practice.
The company reports a network of more than five million experts and says the new financing will accelerate investment in evaluation infrastructure, post-training research and simulated work environments. Participating investors included NVIDIA, Salesforce, Benchmark and General Catalyst.
For enterprises, the stated focus is measuring agents against the work they are expected to perform before expanding their use.
