Enterprise Switching Costs & Land-and-ExpandNarrow moat

Adyen (ADYEN) — moat facet

Embedded deep in the world's biggest merchants, who then grow their spend — the engine that turns wins into compounding.

Adyen's second great source of moat is the depth of its integration into large enterprises and the land-and-expand dynamic that follows — the combination that turns a won customer into a growing, sticky, multi-year relationship. Adyen focuses on large, complex, global merchants rather than small businesses, and for those enterprises, adopting Adyen is a significant, deliberate undertaking: the platform is integrated into the merchant's checkout, its stores, its app, its back-office systems, and its operations across multiple geographies. Once that integration is done, the platform is embedded deep in how the company runs, and moving away is costly, risky, and disruptive — so customers stay. And because they stay, they grow: the defining feature of Adyen's revenue is that the great majority of its growth comes from existing customers spending more, not from winning new ones.

Customers double their share with Adyen over a decade, and growth is spreading beyond the largest three hundred.

The switching costs are real and substantial. A large enterprise that has integrated Adyen comprehensively — across channels, geographies, and systems — faces a formidable project to replace it: re-integrating a new provider everywhere, migrating data and operations, re-validating performance and compliance, and risking disruption to the revenue flow that payments literally are. This friction holds customers in place and gives Adyen a durable base of recurring, growing volume. It is the classic switching-cost moat of deeply-embedded enterprise software, applied to the mission-critical function of getting paid.

The land-and-expand dynamic is what makes those switching costs so valuable. Adyen typically wins a slice of a large merchant's payments — one region, one channel, a share of volume — and then expands: the merchant adds more regions, more channels, more of its volume, and more Adyen products (unified commerce, data, financial services) over time. This is why Adyen's net revenue retention has consistently run above 100%1 — existing customers reliably spend more each year — and why the company can grow rapidly without constantly having to win new logos. A large merchant is a long-term, expanding annuity, and Adyen's book of the world's biggest companies is a powerful, compounding base.

Still, this stays a narrow moat. First, the very largest merchants — Adyen's target customers — are also the most sophisticated and powerful buyers, who deliberately multi-source their payments across several providers to preserve leverage, avoid dependence, and drive down pricing, so Adyen rarely has a customer entirely to itself and competes continually for share of each account. Second, land-and-expand retention can slow as large cohorts mature and as competition for expansion intensifies — the 2023 growth wobble was in part a story of slower expansion. Third, Adyen's enterprise focus, while a source of quality, is also the most contested segment, where Stripe and others fight hardest for the same marquee accounts. The switching costs are genuine and the land-and-expand engine is real and powerful — the best evidence that Adyen owns durable, growing customer relationships. But its customers are giants who hold real power, multi-source by design, and are fought over relentlessly, so the moat is a strong, sticky, growing relationship rather than an exclusive lock — narrow, not wide.

Moat trajectory: Holding steady

Stable. Deep enterprise integration and net-revenue-retention above 100% make a sticky, compounding base — real durability. But the giant customers multi-source by design and hold the pricing power, so it's a strong, growing relationship rather than an exclusive lock.

The number that tests this moat
Reported
Share of wallet by customer age
Under 20% in years 3-7, over 40% after year 12

Land-and-expand made measurable; if newer cohorts stop following this curve, the switching costs are weaker than the old customers suggest.
