Crow

Crow is a Y Combinator (Winter 2026) company building an AI infrastructure platform that makes any web or mobile application AI-native. Instead of a simple chatbot, Crow embeds an agent that connects to a product's own APIs and MCP servers, executes workflows, navigates users between pages, and calls server-side and client-side tools from natural-language commands. Developers add Crow with a single script tag or the React SDK, point it at a REST API via OpenAPI or at an MCP server, and configure the agent in a sandbox. Crow also ships the Envoy CLI, which reads a backend codebase and auto-generates and deploys an MCP server, plus a headless client and React UI component library (Widget and Copilot). Crow is initially positioned for commercial real estate but the platform applies to any software product.

Crow publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agents, MCP, and Model Context Protocol.

Crow’s developer surface includes documentation, getting-started guide, signup flow, CLI, sandbox, and 11 more developer resources.
