Vista Connect

VistaConnect is a UK-specialist B2B data platform for sales, marketing and data teams who need accurate UK company and contact data in their existing workflows. Enrich your CRM, build targeted prospect lists, and query company data from any system that can call a REST API. One pay-as-you-go credit balance covers all three. No per-seat licensing. No monthly minimums. Our commercial database of 4.8M active UK companies and 6.8M decision-maker contacts is enhanced with Companies House filings and officer data, and kept clean by a live feed that suppresses ceased or dissolved companies within minutes. **Data Audit.** Upload a CSV of your customers or prospects and get a full health check in minutes. The audit is free to run and free to review. Every row is matched against 4.8M UK companies to verify addresses, phone numbers and company status, flag ceased or dissolved companies, and show you what's missing.

Useful if you're running quarterly data hygiene, onboarding a new CRM, or prepping an outbound campaign. **List Builder.** Build UK prospect lists in two ways. Apply filters by SIC industry, postcode area, employee count, turnover, year established and contact seniority. Or upload a CSV of your best customers to profile them, generate matching filters and deliver a lookalike list. An interactive UK postcode map visualises geographic coverage before you buy. Every list comes with a 12-month licence, 12 uses per channel (postal, telephone, email), and you only pay for the channels you'll use. For outbound sales, direct mail and multi-channel marketing teams. **UK Company Data API.** Drop in company search, match, enrichment and contact discovery across Salesforce, HubSpot, internal tooling or any REST-capable system.
