Northern Ireland business data

Northern Ireland’s business base runs from Belfast’s growing technology, cyber security and professional services clusters through aerospace, engineering and agri-food manufacturers to hospitality, retail and construction businesses in every county. 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 buyers in Belfast, targeting manufacturers and food producers across the region, or enriching a CRM full of partial records, 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.
