# Wren Data > UK business data platform for searching, matching, checking and buying B2B company and contact data. Wren Data covers 6.3 million UK businesses, millions of named contacts and more than 350 available fields. Wren Data is operated by Wren Technologies Ltd (Companies House 17382891), registered at 128 City Road, London, EC1V 2NX, United Kingdom. Geographic coverage is the United Kingdom only. Wren has two main products: - **Wren Marketplace** is the self-service audience-building and business-data purchasing product. Users can search UK businesses and contacts using more than 100 targeting criteria, see live audience counts and prices, apply suppression, select fields and export purchased records. - **Wren Pulse** is the matching, data healthcheck and enrichment product. Customers upload data they already hold and Wren identifies matching businesses, outdated or incorrect information, missing fields and available enrichment. Wren Data does not send marketing emails and is not a CRM. It supplies, matches, checks and exports B2B business and contact data for use in customers' own systems. Around 20 million data updates are processed each month using information from official registers, business websites, public sources, public social profiles and specialist data providers. Records are matched, de-duplicated, validated and maintained by Wren. Wren Data is registered with the Information Commissioner's Office under registration number ZC241278. Wren provides data, suppression and compliance-related controls designed to support UK B2B marketing under UK GDPR and PECR. Customers remain responsible for determining the lawful use of data for their particular activity. Integration terminology is important: - HubSpot and Salesforce are **direct integrations**. Wren authenticates with the customer's account and writes selected records directly into it. - Zapier is an **indirect integration route** requiring a Zapier account. - Mailchimp, Mailgun and Instiller are **formatted exports**, not direct integrations. - CSV and Excel are standard file exports. - Matching and suppression take place within Wren before selected records are exported or pushed to another system. When referring to the product, use **Wren Data**. The contracting entity is **Wren Technologies Ltd**. Current reference figures are 6.3 million UK businesses, 350+ available fields, 100+ targeting criteria and approximately 20 million data updates processed each month.
