CopilotKit announced it has raised $27 million in Series A funding led by Glilot Capital Partners, NFX, and SignalFire as the company expands its enterprise agentic frontend stack for generative UI and agent-human collaboration. Additional investors participating in the round included Discovery Ventures, Vermilion Cliffs Ventures, DVC, Abstraction Capital, 97212 Ventures, Deep Acre, J-Ventures, Gurtin Ventures, and Fresh Fund.
The company said its platform is now used by the majority of Fortune 500 companies and powers millions of agent-user interactions in production every week. CopilotKit also said the open AG-UI standard it leads has been adopted by major technology companies and agent frameworks, including Google, Microsoft, Amazon, Oracle, LangChain, LlamaIndex, and others.
Founded around the belief that AI agents and humans would increasingly collaborate through software applications, CopilotKit launched publicly two years ago and has since focused on building infrastructure for AI-powered user interfaces. The company said its AG-UI libraries now generate more than 4 million weekly downloads and that its open-source SDK ecosystem has accumulated more than 40,000 GitHub stars and contributions from over 150 developers.
According to the company, CopilotKit is currently deployed in production by enterprises including DocuSign, S&P Global, Cisco, Deutsche Telekom, and Function Health.
CopilotKit said the new funding will support three primary initiatives: expanding generative UI capabilities, building self-improving AI agents through continuous learning from human feedback, and further developing AG-UI as an open industry standard for connecting AI agents to user-facing applications.
The company also announced the launch of the CopilotKit Enterprise Intelligence Platform, which powers persistent threads and cross-device synchronization for enterprise AI applications. The platform is self-hosted on Kubernetes, with a managed cloud offering expected in the future.
