WHERE THE INFORMATION COMES FROM

Built from multiple UK business sources

See more of every business. Wren brings company identity, trading details, contacts and specialist information together, ready to be connected to the right company.

  • Official foundations

    Registered identity, company status, directors, filings and classifications from authoritative UK records.

  • Current business signals

    Websites and public profiles show how a company trades, where it operates and how it can be contacted.

  • Specialist coverage

    Licensed datasets add financial, operational and sector-specific information to the company record.

IDENTITY RESOLUTION

Connecting every detail to the right business

Business information varies in quality and format across sources. Wren combines identifiers, similarity checks and AI-assisted interpretation to find reliable matches, holding back uncertain records.

Key identifiers
Company numbers, domains and other strong identifiers provide the clearest links between records.
Context-aware matching
Names, addresses, postcodes and related details are considered together when an exact match is not available.
Variations and history
Abbreviations, spelling differences, trading names and previous details help identify businesses as their records change.

VALIDATION

Information must pass our checks before it is shown

Company and contact details change over time. Wren continually validates records to identify updates, correct inaccurate information and remove details that are no longer active.

  • Company checks

    Trading status, company identity and address changes are checked against official records.

  • Contact checks

    Names, roles and employment signals help confirm whether someone is still connected to the business.

  • AI-assisted calls

    Email and telephone checks

    Emails are checked for validity and delivery, while telephone screening and verification calls confirm numbers reach the right business.

  • Suppression checks

    Opt-outs, TPS and CTPS indicators, and internal suppression records are applied so restricted information is held back.

WHAT YOU GET

One maintained view of each business

The result is one structured business record combining company details, decision-makers, financial information, locations and specialist data.

  • Everything connected

    Company information, contacts and specialist fields are organised around the same business.

  • Consistent and searchable

    Fields are normalised so businesses can be compared, filtered and exported cleanly.

  • Clear status signals
