HOW WE BUILD IT

From raw sources to data you can act on

We collect from official registers, public web data and licensed partners, match and validate everything in-house, and hand you one clean record per UK business. Here is what happens in between.

COLLECT

Built from sources that matter

We do not rely on a single supplier or dataset. Each record is built from multiple sources, giving us more ways to verify, complete and update it.

We combine data from specialist providers, public sources, business websites and social profiles, processing around 20 million updates every month into our UK business database. We then layer in our own engagement and validation signals, including email and telephone checks, to help produce more accurate, usable business and contact data.
