Discover companies
Filter the UK register, then enrich the ones worth pursuing. Browsing is free — you're only charged when you enrich a website.
Start with a company you know
Verify the business here, watch its signals, or connect Truing to the tool where you work.
Resolve
Turn a UK company domain into its legal entity, or a Companies House company into its domain. You are only charged for verified outcomes: a matched company, a verified domain, or a confident no-web-presence answer. Misses, reviews, and errors are free.
Bulk resolve from CSV
Upload a CSV or text file — one domain per row in Domain → Company mode, or one company number per row in Company → Domain mode. The first column is used; a header row is skipped automatically. Each row is a metered resolution — only verified outcomes are charged.
| Input | Outcome | Detail |

Result
Monitor your companies
Watch companies to receive their registry signals in your feed and webhooks. Add one, send them over from Discover, or bulk-upload a CSV.
Watched companies
Watched companies emit registry signals (new charges, share allotments, director changes, overdue transitions, rebrands) to your feed and registered webhooks. Monitoring requires an active plan; signals stop when your subscription lapses.
Allowance: —
One company number per row; first column used, header skipped. Adds are subject to your plan's watch allowance.
