CopilotKit, a Seattle-based startup, has secured $27 million in Series A funding led by Glilot Capital, NFX, and SignalFire. The investment will be used to bring the company’s enterprise toolkit to market, which is built on top of its popular AG-UI protocol.

The AG-UI protocol enables developers to create seamless experiences for users by allowing AI agents to live inside applications, understand user actions, and provide useful interfaces instead of relying on text-based interactions.

CopilotKit’s founders believe that the current approach to AI in apps is clunky and doesn’t make the most of what AI agents can do. They argue that enabling agents to interact with users through dynamic interfaces will lead to more intuitive and user-friendly experiences.

The company’s toolkit provides developers with full control over how much their AI agent can change the UI, allowing them to choose between pixel-perfect or broad building blocks that the AI can assemble as needed.
