Ownership and roll-up map: connect parents, subsidiaries, investors, and acquisitions to identify platform/add-on relationships, cross-sell paths, and fragmented markets.

How would a GTM team use it?

1. PE screen: score targets with Harmonic.ai operating signals, then verify the top decile against filings, management commentary, and at least one independent source. 2. Revenue trigger: launch outreach only when a Harmonic.ai signal indicates an active project, budget event, stack change, hiring push, or market expansion. 3. Relationship graph: map Harmonic.ai's ownership and transaction links to surface add-on targets, portfolio overlaps, channel partners, and warm paths.

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.
