CopilotKit, a Seattle-based startup, has raised $27 million in Series A funding to help developers deploy AI agents directly inside applications. The company aims to move beyond clunky chatbot experiences by enabling AI to generate dynamic, interactive user interfaces.
CopilotKit Funding: A $27M Boost for App-Native AI
Glilot Capital, NFX, and SignalFire led the funding round. TechCrunch exclusively reported the news. The investment signals strong market confidence in CopilotKit’s vision for AI agents that live within apps, not just as text-based overlays.

Co-founders Atai Barkai and Uli Barkai believe traditional AI chatbots fall short. Users often struggle with long text responses. For example, booking a travel itinerary via chat requires scanning reams of text. CopilotKit’s solution integrates AI directly into the app’s interface, offering a smoother experience.
What is AG-UI Protocol? The Backbone of CopilotKit
At the core of CopilotKit is the AG-UI protocol. This open-source standard defines how AI agents connect to and communicate with user interfaces. It provides features like streaming chat, front-end tool calls, and state sharing. Developers can use AG-UI to build human-in-the-loop functionality easily.

The protocol works alongside the Model Context Protocol (MCP) and Agent2Agent (A2A). Major AI infrastructure providers, including Google, Microsoft, Amazon, and Oracle, now support AG-UI. Popular frameworks like LangChain, Mastra, PydanticAI, and Agno also integrate with it.
Key Features of AG-UI
- Streaming chat: Real-time communication between users and AI agents.
- Front-end tool calls: Agents can trigger UI actions directly.
- State sharing: Maintains context across interactions for easy workflows.
- Human-in-the-loop: Allows users to review and approve agent actions.
Enterprise AI Tools: CopilotKit’s Commercial Offering
CopilotKit is building an enterprise toolkit on top of AG-UI. This includes support, self-hosted deployment, and other business-critical features. The company recently launched CopilotKit Enterprise Intelligence, a self-hostable bundle for deploying agents within apps.
Enterprise customers include Deutsche Telekom, Docusign, Cisco, and S&P Global. Atai Barkai told TechCrunch that a large portion of Fortune 500 companies now use the protocol and tools in production. The company sees millions of installs per week.
Why Enterprises Choose CopilotKit
Atai emphasized two key demands from enterprises: optionality and self-hosting. Many companies already use Google, Amazon, Oracle, or Microsoft stacks. They want tools that integrate with existing infrastructure, not replace it. CopilotKit’s horizontal approach supports whatever agent framework, cloud provider, or backend an enterprise already uses.
This contrasts with vertically integrated platforms like Vercel’s AI SDK. CopilotKit aims to remain a neutral standard while monetizing through enterprise-grade features.
Dynamic User Interfaces: The Competitive Edge
CopilotKit’s flexible UI generation sets it apart. Developers can provide specifications and building blocks for dynamic interfaces. The AI agent then generates UIs to fit the context. For example, a user asking for revenue breakdown by category sees a pie chart instead of a text paragraph.
Atai explained that developers have full control over how much the AI can change the UI. They can choose pixel-perfect designs or broad building blocks. This flexibility makes CopilotKit suitable for various use cases, from data dashboards to customer support tools.
Comparison with Competitors
| Feature | CopilotKit | Vercel AI SDK | Assistant-ui |
|---|---|---|---|
| Open-source protocol | Yes (AG-UI) | Yes | No |
| Self-hosting | Yes | Limited | No |
| Enterprise support | Yes | Yes | No |
| UI generation | Dynamic | Static | Static |
AI Agent Deployment: The Market Environment
The market for enterprise AI agents is heating up. Vercel’s open-source AI SDK offers similar capabilities. Assistant-ui provides components for building AI chat interfaces. OpenAI’s Apps SDK works only within ChatGPT. CopilotKit differentiates itself with a horizontal, enterprise-friendly approach.
Uli Barkai, head of growth, stated that the company’s strategy is to be the default choice in the ecosystem. They monetize top enterprises while keeping the open-source version free for 95% of users. This balance helps maintain adoption and trust.
Future Plans and Team Growth
CopilotKit currently has about 25 employees. The new funding will support team expansion. The company plans to hire more engineers, sales professionals, and customer success managers. Atai noted that the demand for app-native AI agents is growing rapidly.
The startup also aims to deepen integrations with cloud providers and AI frameworks. They want to make AG-UI the standard for connecting AI agents to user interfaces. With $27 million in funding, CopilotKit is well-positioned to lead this space.
Conclusion
CopilotKit’s $27 million funding round highlights the growing demand for app-native AI agents. The AG-UI protocol provides a standardized way for AI to interact with user interfaces. Enterprises benefit from optionality, self-hosting, and dynamic UI generation. As the market for AI tools expands, CopilotKit’s open-source approach could become the default choice for developers building intelligent applications.
