HOW OUR DATA IS BUILT

An illustration of Wren's data process: detailed extracts from official registers, licensed datasets, business websites and public profiles flow into the Wren data engine, which matches, combines, cleanses, verifies and updates them — rejecting information it cannot confirm — and produces one verified business record spanning company, contact, financial, geographic, compliance and specialist information, drawn from 350+ available fields.

  • Multiple sources Official, licensed and public information is compared and connected.
  • 20M updates each month New and changed information is processed continuously.
