Hilton Hotels – AI Personalization Across Guest Journeys

For Hilton, we delivered an enterprise-grade AI system that elevates guest experiences from pre-check-in to post-stay. Our solution uses behavior modeling to tailor room recommendations, amenities, and upsells during booking. It supports automated concierge services via chat, helping guests request towels, schedule spa appointments, or get local tips instantly. By combining NLP with guest data and real-time hotel system integration, the AI anticipates guest needs without any human prompt. The hotel chain achieves individualized service across all properties through AI-driven personalization. The result is smoother stays, fewer front-desk calls, and stronger loyalty scores.

Project Overview

Client: Hilton Hotels (6,500+ properties worldwide | $10.2B revenue)
Challenge: Generic guest engagement and over-reliance on front-desk for service delivery
Goal: Deploy AI-driven platform to:
- Personalize room and service recommendations at each touchpoint
- Offer automated concierge services through AI chat
- Reduce support load and enhance post-stay loyalty interactions
Team: 9 (3 ML Engineers, 2 NLP Specialists, 2 Integration Engineers, 2 CX Designers)
Timeline: 6 months (MVP → Pilot in Asia & US → Global rollout)

“This AI infrastructure elevated our brand experience. With GenX, we’re delivering luxury personalization at Hilton scale.”

Loyalty scores dipped due to inconsistent experiences across regions

Technical Hurdles:

Real-time sync with multiple PMS platforms and on-site systems (spa, housekeeping, etc.)
Capturing and responding to unstructured guest requests using NLP
Creating cross-touchpoint personalization without breaching privacy protocols
