Amadeus reinvests heavily in R&D, with a spend equivalent to its #3 competitor's total revenue. This creates a widening technology and product gap that smaller players cannot bridge, fortifying its market leadership and making it increasingly difficult for others to keep up.

Amadeus maintains its "gorilla" status by being beneficial to its ecosystem, acting as a variable cost for airlines and sharing economies of scale. The ultimate test of a great business is when competitors hate you but customers love doing business with you for the same reasons.

Instead of selling software to traditional industries, a more defensible approach is to build vertically integrated companies. This involves acquiring or starting a business in a non-sexy industry (e.g., a law firm, hospital) and rebuilding its entire operational stack with AI at its core, something a pure software vendor cannot do.

While a strong business model is necessary, it doesn't generate outsized returns. The key to successful growth investing is identifying a Total Addressable Market (TAM) that consensus views as small but which you believe will be massive. This contrarian take on market size is where the real alpha is found.

Despite investor focus on its well-known distribution business, Amadeus's Air IT division (inventory, reservation management) now generates 50% of group profits. This less visible, mission-critical software segment is the company's most profitable and formidable moat.

Amadeus was formed by major airlines to create a neutral distribution system. This origin story provided immediate scale, credibility, and deep industry integration, creating a powerful competitive moat from day one that would be nearly impossible for a startup to replicate.

When airlines select an IT provider for their central nervous system, the provider's financial stability is paramount. Amadeus's strong balance sheet is a competitive weapon against more levered peers, as customers cannot risk their core operations on a financially unstable partner.

Financial models struggle to project sustained high growth rates (>30% YoY). Analysts naturally revert to the mean, causing them to undervalue companies that defy this and maintain high growth for years, creating an opportunity for investors who spot this persistence.

AI travel agents will likely focus on top-of-funnel search but will still need an aggregator like Amadeus to access complex, fragmented industry data. Amadeus's core IT backbone remains mission-critical in any AI-driven travel world, securing its position.
