Shapes what 'good data' means.
How Anthropic buys data
Open roles (updated Aug 2026) for 'Data Operations Manager, Human Data' (owns data strategy and 'strategic vendor partnerships', $270k-365k) and 'Product Management, Human Data Platform' (labeling interfaces, vendor tooling, crowdworker sessions, data-quality KPIs). The Information (via TechCrunch, Sep 2025) reported Anthropic leaders discussed spending over $1B on RL environments, working with Mercor and reportedly Mechanize. Surge AI publicly marketed that its human data powers Claude 3 (2024). Anthropic Labs' own design grader (Mar 2026) scores design quality, originality, craft and functionality, which is the closest public sign of design-taste evaluation.
Human Data sits alongside research: Data Operations Managers own data strategy and vendors for research teams (RLHF, safety, tool use, agentic), and a Human Data Platform team builds labeling interfaces, environment simulation and vendor tooling. RL environments have their own infra team ('Environments Infrastructure'). Claude Design is built inside Anthropic Labs (Krieger/Mann), and Jenny Wen leads design for Claude.
Known vendors: surge-ai, mercor, mechanize
