Case Study: IHG Hotels & Resorts scales real-time trusted data with Reltio

IHG Hotels & Resorts scales real-time trusted data across global brands

IHG Hotels & Resorts partnered with Reltio to modernize its legacy master data management approach and create a single, trusted view of guest, business, and owner data. The company needed a cloud-native, scalable platform that could support real-time information, global data residency requirements, and future growth across its brands and operations.

Reltio implemented Reltio Data Cloud to replace legacy MDM, consolidate data from three core systems, and enable real-time sync with five operational systems, including booking and loyalty. The results included a 34% reduction in duplicate profiles, resolution of 90–95% of performance issues, and the ability to process 1.5 million messages per day, while also improving guest experiences, marketing personalization, traceability, and operational decision-making.
