Overview
CompanyCat is built to help users search, understand and monitor UK companies through a clear and practical web experience.
The product uses Companies House-derived data as its core source for structured company information and public business records.
The current focus is company discovery, company profiles, Radar signals, watchlist workflows and alert-style product validation.
For more detail on how the data is sourced and how signals are derived, see the Methodology page.
Data source
CompanyCat currently uses Companies House-derived company profile data as its core public data source.
That data is processed by local Python ETL scripts and served through a Cloudflare D1-backed search and company profile stack.
Critical business or legal decisions should verify details directly against the official Companies House record.
