# InsightBase

> InsightBase is a UK-first company intelligence platform for finding, understanding, and monitoring registered UK companies using structured public-register data.

Public company profiles use the Companies House company number as the durable identifier. Company names can change, so agents should prefer the canonical profile URL returned by InsightBase and treat the company number as the entity key. Profiles are server-rendered and may include registration details, officers, people with significant control, filings, charges, establishments, disqualifications, sponsor-licence matches, and headline financial facts where those records are available.

InsightBase distinguishes shared canonical public-register facts from private workspace overlays. Private workspace notes, tags, segments, and enrichment are not published on public company profiles. Public information is provided for research and decision support; users should verify material decisions against the cited official source.
