Amadeus IT Group

One of the top three global distribution systems (GDS) and a dominant travel IT provider, with growing relevance in travel data and audience targeting for AdTech applications.

Amadeus IT Group is a leading provider of advanced technology solutions for the global travel industry, headquartered in Madrid, Spain. Founded in 1987 as a joint venture among major European airlines, Amadeus has grown into one of the world's largest travel technology companies, serving airlines, hotels, travel agencies, rail operators, and other travel providers. Its core business revolves around a global distribution system (GDS), reservation platforms, and a broad suite of IT solutions covering revenue management, operations, and customer experience. While Amadeus is not primarily an AdTech company, it has made strategic acquisitions and investments in companies that intersect with digital marketing, data analytics, and advertising technology relevant to the travel vertical. Its vast repository of traveler data and booking intelligence positions it as a significant player in travel-intent data and audience targeting, which are increasingly relevant to AdTech ecosystems focused on travel advertising. Amadeus serves over 190 countries and processes billions of transactions annually, making it one of the most data-rich companies in the travel sector. Its market position as a near-duopoly GDS provider alongside Sabre and Travelport gives it substantial leverage in travel data monetization, which increasingly overlaps with programmatic advertising, personalization, and travel-focused audience segments used by advertisers and publishers.
