Central Reservation System

SynXis is one of the two or three dominant global hotel central reservation systems, holding rates, inventory and availability and pushing them to the brand website, OTAs, GDS and voice channels; it is bundled with a booking engine, a PMS (Property Hub), a retailing module (Retail Studio) and a unified guest profile (Guest Experience). The business began as SynXis Corporation in 1996, was bought by Sabre in 2005 for $41M, and was sold by Sabre to private-equity firm TPG for $1.1B in a deal that closed on 3 July 2025. On 27 January 2026 it rebranded from Sabre Hospitality Solutions to Aven Hospitality under CEO Teresa Mackintosh — sabrehospitality.com now 301-redirects to avenhospitality.com, so the customer-facing name is changing. It reports 35,000+ hotels in 175 countries and 600+ integrations, and in July 2023 it acquired UK-based Techsembly specifically for hotel gift-card and property e-commerce capability aimed at the luxury segment.
