Editorial take
Our qualitative read on the source — tone, framing and trust posture.
Excellent fit for a serious OSINT product because it is structured, official and defensible.
Integration stance
Build, buy or defer. What shape the product integration would take, and why.
Integrate early for company/entity intelligence. Use as a normalization layer in company reports.
Ethics and compliance
What to handle carefully, and what must not ship without sign-off.
Do not treat missing LEI as negative evidence. Many legitimate entities may not have a LEI.
Clarify coverage limits and avoid implying universal company registry coverage.
