About CompanyCat

A practical UK company search and monitoring product built around Companies House-derived data.

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.
