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.
A polished website, vendor claim, funding story, or public figure connection needs legal-entity grounding before deeper reporting or due diligence.
This stack supports due diligence and public-interest research, not legal clearance. High-stakes decisions still need primary-source review and qualified advice.
Use these connected pages when the same investigation needs a different entry point or a deeper decision aid.
