WHAT WE HOLD

What we hold for the South East

Every record includes

  • Verified company record
  • Named decision makers
  • Job titles & departments
  • Business email & telephone
  • Employee numbers & size
  • Financials where available

The South East is one of the UK’s most varied business regions: science and technology around Oxford and Reading, financial and professional services in the commuter belt, marine and port businesses around Southampton and Portsmouth, creative and digital firms in Brighton, and the freight and logistics networks that serve Gatwick and Heathrow. Wren Data gives you direct access to these companies, with verified addresses, workforce sizes, trading status and direct contact details for the people who make the buying decisions.

Whether you are prospecting technology and science buyers, targeting logistics operators near the airports and ports, or enriching a CRM with records from Kent to Buckinghamshire, our platform lets you filter by town, postcode, sector and company size in seconds — then export a list you can act on the same day.
