Corporate Relationship Mapping

via “corporate-hierarchy-and-subsidiary-mapping”

Real-time company and person data enrichment API.

Unique: Clearbit's hierarchy mapping uses SEC filing analysis (10-K/10-Q forms), business registration database lookups, and web crawling to reconstruct corporate ownership structures, with LLM-based entity resolution to handle name variations and complex holding company relationships across multiple jurisdictions.

vs others: More comprehensive subsidiary mapping than basic domain ownership lookups due to SEC filing analysis and acquisition tracking, though with less real-time accuracy than dedicated corporate intelligence platforms (Dun & Bradstreet, Bureau van Dijk) for complex international structures.
