Mercor
Mercor is a platform that connects domain experts with AI companies for training data, model evaluation, and post-training work. Professionals in medicine, law, engineering, finance, and hundreds of other fields get matched to remote contract roles where they review model outputs, create training examples, and apply expert judgment to improve large language models. The same network powers frontier research for top AI labs and custom agent deployments for enterprises.
