AMW Analysis
Mercor connects vetted domain experts—scientists, doctors, lawyers—with AI labs to support training, evaluation, and reinforcement learning of foundational models, positioning itself around the human-data bottleneck in frontier AI development. Founded in 2023 and based in San Francisco, the company has raised $483.6 million to date, including a $100 million Series B in February 2025 at a $2 billion valuation from investors such as Felicis, Benchmark, General Catalyst, DST Global, and Menlo Ventures. Subsequent news flow shows a rapid step-up: a $350 million Series C reported in October reportedly valued the company at $10 billion, and by July it was in early-stage talks for a new round at a $20 billion valuation alongside reported revenue doubling to $2 billion, attributed to rising AI training demand. The company also acquired Deeptune, an AI agent training firm. Alongside its core data-labeling and expert-vetting business, Mercor has expanded into an AI-native talent platform automating sourcing, screening, interviewing, and onboarding through specialized AI agents, broadening its footprint from AI-lab data supply toward general hiring automation.
