## In short

Seattle's CopilotKit raised $27M Series A from Glilot, NFX, and SignalFire and shipped CopilotKit Enterprise Intelligence — a self-hostable bundle for the AG-UI protocol now adopted by Google, Microsoft, Amazon, Oracle, LangChain, Mastra, PydanticAI, and Agno.

## What it is

CopilotKit, a Seattle-based open-source company, raised $27M Series A and launched CopilotKit Enterprise Intelligence — a self-hostable distribution for AG-UI, the open protocol that wires AI agents into existing application UIs. The protocol standardizes streaming chat, frontend tool calls, and shared agent–UI state.

## How it works

AG-UI runs alongside Model Context Protocol (MCP) and Google's Agent2Agent (A2A). MCP gives agents tools, A2A handles agent-to-agent handoff, AG-UI handles the agent-to-UI rendering channel. CopilotKit's React/Angular SDK speaks AG-UI so an agent can return interactive components and update them as state changes.

## Why it matters

Google, Microsoft, Amazon, and Oracle now support AG-UI; LangChain, Mastra, PydanticAI, and Agno integrate it. Enterprise adopters include Deutsche Telekom, Docusign, Cisco, and S&P Global. Round was led by Glilot Capital with NFX and SignalFire — proceeds back the new Enterprise Intelligence offering and team expansion.

## Who it's for
