Seattle-based CopilotKit raised $27 million to scale its open-source protocol, AG-UI, which enables autonomous AI agents to interact directly with software interfaces across Fortune 500 environments.

The rapid expansion of the algorithmic state reached a new milestone this week as Seattle-based CopilotKit announced a $27 million funding round to solidify its position as the primary interface for enterprise AI agents. The capital infusion, led by Glilot Capital, NFX, and SignalFire, includes a $20 million Series A and a previously undisclosed $7 million seed round. The investment arrives as North American cloud providers drastically revise their 2026 capital expenditure forecasts to $830 billion, signaling a massive infrastructure buildout for autonomous systems.

Founded by brothers Atai and Uli Barkai, CopilotKit has pivoted from its origins as a podcast platform to become a critical player in the “agentic AI” boom. The company’s core offering is AG-UI (Agent-User Interaction), an open-source protocol designed to solve the friction between autonomous agents and the software they inhabit. While other protocols like Anthropic’s MCP focus on connecting agents to tools, AG-UI focuses on the human element, allowing agents to generate interactive charts, update dashboards, and execute actions within existing application interfaces.

This move toward standardization comes as major industrial players and financial institutions signal total commitment to the AI transition. On May 5, JPMorgan Chase CEO Jamie Dimon publicly endorsed the trillion-dollar AI expenditure trend, while IBM and Aramco announced a collaborative push into agentic AI for the industrial sector. CopilotKit’s platform is already deeply embedded in this shift, claiming adoption by more than half of the Fortune 500 and recording millions of weekly installs through its open-source repository, which has amassed over 40,000 GitHub stars.

Unlike proprietary ecosystems offered by Big Tech giants, CopilotKit positions itself as a vendor-neutral alternative to the OpenAI Apps SDK and Vercel AI SDK. This horizontal approach allows enterprise clients—including Deutsche Telekom, Cisco, and S&P Global—to maintain digital sovereignty by integrating agents across diverse cloud providers and backend frameworks. The startup’s enterprise tier, CopilotKit Enterprise Intelligence, provides the self-hosted infrastructure necessary for persistent conversation threads and real-time learning, catering to organizations wary of third-party data silos.

The funding will support the expansion of the company’s Seattle-based engineering team as they compete in an increasingly crowded security and automation landscape. On the same day as CopilotKit’s announcement, Zimperium launched its own agentic solutions for mobile security, and Rakuten Advertising debuted an AI optimization agent for marketing. As these autonomous entities proliferate, the battle for the protocols that govern their interaction with human users is becoming the next frontier of the data economy.
