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.

Capture, debug, and replay failed webhooks before your users notice
Each endpoint gets a HookWatch URL that receives and forwards webhooks, recording status, provider, response code, latency, and attempt count for every delivery.
Re-send an exact captured payload after a fix, with manual replay and retry policies instead of recreating the event by hand.
Failed deliveries are categorized by reason — signature mismatch, timeout, 5xx, rate limit — so you know what broke without grepping logs.
Recurring failures group into a single incident routed to Slack or a webhook, so a flaky endpoint shows up as one problem.
