CopilotKit raises $27M to build app-native AI agents for developers

What's the deal? CopilotKit, an open-source startup that helps developers embed AI agents directly into their applications, has raised $27M in new funding. The company provides tools that let developers deploy AI copilots and agents that live inside apps — rather than sitting alongside them as separate chatbots or tools.

Why now? The AI agent landscape is evolving fast. While most AI tools still operate as standalone assistants, there's growing demand for agents that can act within the context of an application — reading data, triggering actions, and interacting with users natively. CopilotKit is positioning itself at the centre of that shift, offering an open-source framework that lowers the barrier for developers to build these experiences.

The signal: CopilotKit, classified as a "breakout" company on Dealroom, is riding a wave of developer enthusiasm — its open-source framework has already attracted significant community traction. The $27 million raise underscores investor appetite for infrastructure-layer plays that sit between large language models and the applications that consume them, a space where capturing developer adoption early can translate into durable competitive moats.
