What We Set Out to Improve.

Industry
Hospitality

Global resort group requiring a unified guest profile across disconnected Property Management Systems (PMS).

How We Worked
Dedicated product team

Data Architect + 3 Backend Engineers + DevOps Lead embedded within the Guest Experience division.

Goal
Personalization & Yield Optimization

Consolidating stay history, preferences, and spend patterns into a single, reliable connected data.

What We Built
Global Connected Data Platform

A practical solution designed around the client’s existing tools, teams, and day-to-day workflow.

What Was Getting in the Way.

The client operated 500+ properties across 40 countries, each using localized Property Management Systems (PMS). This business-wide fragmentation meant a VIP guest at a Paris resort was a stranger when checking into a Maldives location.

The biggest issues were service inconsistency, upsell leakage, and privacy compliance. The team needed a faster, clearer way to manage the work while keeping the right checks in place.

Service Inconsistency
Preference data trapped in local separate systems caused inconsistent guest experiences across the global portfolio.
Upsell Leakage
Lack of live spend behavioral data prevented AI assistants from triggering relevant room or spa upgrades.
Privacy Compliance
Manual data sharing between regions violated evolving GDPR and local personal information control requirements.
