What does BuiltWith return?

Clay catalog fields: Technologies - Count; Technologies Used; Technologies description. Verified public actions: Find Technology Stack with BuiltWith: This action leverages BuiltWith's technology detection capabilities to identify the software stack used by a specified website..

What can you derive from it?

1. Stack maturity and replacement windows: infer operating complexity, integration needs, vendor concentration, and likely migration targets from installed products and first/last-seen dates.

How would a GTM team use it?

1. Revenue trigger: launch outreach only when a BuiltWith signal indicates an active project, budget event, stack change, hiring push, or market expansion. 2. Competitive watch: snapshot BuiltWith weekly and alert on relative changes in stack, traffic, ads, search visibility, reviews, or product activity.

What are the caveats?

Verified against Clay's live public integration catalog on 2026-10-17. The catalog data-point list is integration-wide; a particular action may return only a subset. No separate field-level Clay University output section was found in the public documentation corpus; do not infer undocumented fields. Coverage, freshness, geography, credit cost, and BYO-account requirements vary by action and plan. Estimated or inferred values should be validated before investment, legal, credit, or other high-stakes decisions.
