Scrutica
Of the 95,799 parent-subsidiary relationships in this graph, 58,557 — 61% — were lifted directly from SEC EDGAR (Exhibit 21 subsidiary lists and the filings around them), and every one carries the sec.gov URL of the document it was read from. Click any of those hops and you land on the primary source, not a citation of a citation. The rest of the graph fills in private companies and foreign parents the SEC never sees; those edges are flagged as such and never dressed up as something they aren’t.
Accepts: organization name (Equinix), ticker (NVDA), CIK (1045810), LEI (20-char), licensed-database company id (12817-90), BIS-designated entity, sovereign LP (“Mubadala Investment Company”), organization alias, or canonical Scrutica id (org-*). Fuzzy substring fallback runs only when nothing else matches, and lands with low confidence stamped on it.
The Investigator is entity-centric— you give it an entity, it climbs that entity’s ancestors. The Governance Reach Explorer is rule-centric— you give it a regulatory instrument (BIS Entity List, EU AI Act Article 51) and it returns every entity the instrument reaches. Same ownership substrate, opposite query directions; the Investigator is what an analyst opens to build a case, the Reach Explorer is what a policy evaluator opens to score one.
Each hop on an entity page carries data_source, source_url (where one exists), as_of_date, and confidence right on the line — no footnotes to chase. Affiliate closures of BIS / OFAC / equivalent designations sit in the right rail; so do sovereign LP commitments routed through a fund. The page is text-first on purpose; researchers paste sentences into their citation managers, not screenshots.
