Workflow notes

This collection is for analysts who need to move from a company name or website into a clearer picture of entity identity, public records, web presence, and risk context.

Use this stack when

A polished website, vendor claim, funding story, or public figure connection needs legal-entity grounding before deeper reporting or due diligence.

Recommended sequence

  • Start with OpenCorporates to test the legal-entity layer where registry coverage is available.
  • Use OpenSanctions when sanctions, PEP, or watchlist context is relevant, but treat matches as identity-resolution leads.
  • Use Aleph when the case becomes document-heavy and prior investigative material matters.
  • Use BuiltWith, Wappalyzer, and SecurityTrails to understand the web footprint behind a company domain.
  • Add Hunter only when staff-email patterns or domain-linked contact clues are part of the research question.

Specialist accountability sources

  • Use the ICIJ Offshore Leaks Database to test whether an entity, person, address, or intermediary appears in published offshore leak datasets; a match does not establish illegality, beneficial ownership, or current control.
  • Use OpenSecrets when U.S. campaign-finance or lobbying records are relevant to the relationship under review, and separate documented money flows from claims about motive or influence.

Editorial guardrail

This stack supports due diligence and public-interest research, not legal clearance. High-stakes decisions still need primary-source review and qualified advice.
