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.

AI code review that runs your app on every pull request
TestDriver reviews every pull request automatically, reads the diff with its vision agent, and generates end-to-end tests straight from the PR content to prove the new behavior works.
Tests run your actual application in a real desktop sandbox—clicking, typing and reading the screen—so they catch runtime and visual bugs, not just code diffs.
When the UI shifts and a cached element no longer matches, the AI finds it again, updates the cache and continues, so tests survive redesigns without rewrites.
Once a test passes, TestDriver opens a fresh pull request with the generated Vitest test code committed, so coverage lands in your repo alongside the change it protects.
