This page is the intersection of two independently computed cohorts:
United Kingdom & Ireland and
Customer Relationship Management (CRM). A provider appears here only when it is
already a member of both. United Kingdom & Ireland membership is matched on tag, name pattern, stated HQ,
so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
Work with this as data
Every region here is available over the APIs.io API and to AI agents over MCP.
