Build GTM systems that turn data into revenue
Query 200+ data and AI providers from one contract and cascade across them to maximize coverage and accuracy.
Clay's global agent and account agents research companies and people with AI, then score and route leads automatically.
Monitor job changes, promotions, hiring activity, and other buying signals to target accounts at the right moment.
Chain enrichment, reasoning, and outreach into long-running workflows, or build programmatically with Clay's CLI, API, and MCP tooling.

The open-source diagramming studio for builders
Paste a public GitHub repository and OpenFlowKit reads its files in the browser to draw modules and connections, with every arrow cited to the source line it came from.
29 diagram tools for Claude Code, Codex, Cursor, VS Code, Windsurf or any MCP client, so an agent can draw on the diagram you have open, one undo away.
Write or paste Mermaid, D2 or Structurizr; the text and the canvas remain the same diagram, so you can round-trip between syntax and visuals.
Move from system context to containers to components in linked views that all stay grounded in a single architecture model.
