Our Mission
Making Companies House Data Easier
Companies Catalogue is a suite of data products designed to improve access to Companies House data for teams building ingestion pipelines.
The approach
Companies House provides valuable data, but it is often obscured by complex formats and a lack of integration across their data products. Companies Catalogue aims to join the dots and simplify ingesting this data. Our philosophy is to preserve source data while making it more accessible through modern delivery formats.
Built by Brian Evans
Founded by Brian Evans, a software and data engineer with a focus on Companies House data. Brian is the creator of companies.stream, a popular tool for developers integrating with the Streaming API, and the author of chguide.co.uk. He also consults for enterprises on data pipeline engineering.
Project Mission
The modern data ecosystem has evolved, but official Companies House data products haven't kept up. This project exists to fill in the gaps, providing reliable, modern data products that integrate seamlessly with the official API.
This service simplifies the developer experience, enabling teams to focus on building features rather than wrestling with legacy file formats.
Built with Transparency
Open Source
The entire data pipeline code for Companies Catalogue is open source on GitHub and available for inspection.
Sustainable Model
While most data products are free, some are paid to ensure the service remains sustainable.
