RETAIN is the AI-native Customer Experience Platform for UK B2B SaaS teams. It unifies post-sale customer data and runs the operational work — automated QBR client portals, explainable 8-signal health scoring, onboarding Flight Plans, playbook automation, a built-in service desk, NPS and CSAT surveys, customer education, and a knowledge base — so lean CS teams manage their portfolio without a CS Ops function. Transparent published pricing from £149/month, live in days. Built by CX Advisory Ltd, registered in England & Wales, UK GDPR-compliant with EEA data residency. Book a demo at cxretain.co.uk
