Windmill Raises $12 Million to Expand AI Tools for Workforce Context

Windmill has raised 12 million dollars in seed funding led by Inspired Capital, with participation from Primary Venture Partners, Founder Collective, and Oceans Ventures, announced in a press release. The company has grown to more than 100 customers since launching its performance review product in November 2025.

Windmill builds what it calls a context graph for organizations, a system that provides a continuously updated understanding of employees and their work. The company’s platform integrates with tools such as Slack, GitHub, and Google Workspace to collect and organize information about team performance and collaboration.

The first product built on this infrastructure is an AI supported performance review tool. It allows managers and employees to generate reviews more quickly by using data from existing work systems. The reviews are completed faster and with higher satisfaction rates compared to traditional methods.

Windmill’s context graph is accessible through its AI agent Windy, the Windmill web application, and through MCP and API integrations. The company describes the system as a foundation for making better workforce decisions by connecting information that is typically scattered across multiple tools and conversations.
