What does Windmill do?
Windmill is an AI-native HR platform building a "context graph" of a company's workforce, integrating with Slack, GitHub, and Google Workspace to continuously capture evidence of how work actually happens. Its first product is an AI-assisted performance review system, used by 100+ customers including Kalshi, Rho, and Merge since its November 2025 launch. The New York team raised a $12M seed led by Inspired Capital in April 2026.
