# Deeptune acquisition

Mercor announced a $750 million Series D at a $20 billion valuation, a round that included an employee tender and participation from Benchmark, NVIDIA, Salesforce and others. For the past two years Mercor built infrastructure to train and evaluate frontier models on real-world work for frontier labs, drawing on a network of more than five million experts paid to train models from their own knowledge. It is now offering that expert network, evaluation methods and post-training infrastructure to big tech, open-model developers, application-layer companies and Fortune 500 firms, so enterprises can post-train a capable open model and build custom evals around their own workflows.
