Net Revenue Retention (Land-and-Expand)Narrow moat

The clearest financial evidence of Adyen's stickiness is its net revenue retention, which has consistently run above 100%¹ — meaning that, in aggregate, existing customers spend more with Adyen each year than the year before, even before counting any new customers won. This is the land-and-expand dynamic quantified: Adyen lands a slice of a large merchant's payments and then expands within the account as the merchant adds channels, geographies, volume, and products, so the installed base grows organically. Net revenue retention above 100% is the signature of a high-quality platform business, and it means the great majority of Adyen's growth comes from its existing customers rather than from the harder, more expensive work of constantly winning new ones.

This dynamic is enormously valuable. It makes growth efficient (expanding an existing, integrated customer costs far less than acquiring a new one), predictable (the installed base is a compounding foundation), and durable (the same switching costs that retain customers also capture their growth). A book of the world's largest, growing companies, each expanding its Adyen footprint over time, is a powerful engine. The fine print is that net revenue retention is not fixed: it can slow as large cohorts mature (a customer that has already put most of its volume on Adyen has less room to expand), as competition for the expansion intensifies, or as the merchant's own growth slows. The 2023 wobble was partly a story of expansion decelerating. Net revenue retention above 100% is genuine, high-quality evidence of a sticky, compounding platform and one of the strongest features of Adyen's business; but it is a rate that must be sustained against maturing cohorts and intensifying competition, not a constant to be assumed — a powerful engine whose pace can slacken, as the market was sharply reminded.
