Checkout.com — What I Think
Checkout.com is what happens when you take Adyen’s thesis seriously and decide there’s room for two. But only if you’re willing to live in the parts of the world the others find inconvenient.
The shared insight is the right one. Own the full stack, gateway through acquiring, in one system, instead of stitching vendors together. The legacy world is integration debt all the way down, and the modern winners are the ones who built one clean path for a transaction to travel. Checkout.com bet on that same architecture. So at the level of vision, the interesting question isn’t “what did they understand that nobody else did.” It’s “what did they understand that Adyen, the obvious incumbent of this exact idea, didn’t bother to prioritize.”
The answer is the hard geographies. The Middle East. Emerging markets. The merchants whose flows route through messy, fragmented, locally-specific rails that a Silicon-Valley-or-Amsterdam roadmap treats as edge cases. Checkout.com leaned into local acquiring and local methods in places where “just connect to the card networks” is the start of the problem, not the end. That’s a real choice. The most defensible position in payments is often the one that needs the most unglamorous local plumbing, because plumbing is exactly what competitors won’t bother to lay.
Second thing they read correctly: performance is a product. They sell on authorization rates, the unsexy reality that a meaningful share of legitimate transactions silently fail, and clawing those back is pure money for a merchant. Most buyers don’t even know to ask. Checkout.com made the invisible failure rate the pitch. Sophisticated read on where value actually leaks in a payment.
Where the risk lives: this is, again, mastery over the existing card-and-bank rails, not a bet on new ones. Excellent execution of a known model. And being the strong number-two-or-three in “full-stack modern processor” means the moat is operational, not structural. You have to stay better, every quarter, at a thing several well-funded companies are also good at. That’s a treadmill, not a fortress. The escape is owning something the others can’t copy, deep local rails in markets that matter and nobody else wants to work in. To their credit, that’s exactly where they’ve been digging.
Favorite & worst CEO
This is a founder-led company, so:
On its leadership. Guillaume Pousaz built Checkout.com on the conviction that a unified full-stack processor could be built fresh and could win specifically by going where the incumbents found the work too messy, emerging markets, local acquiring, the authorization-rate fight others ignored. I connect with that. Competing not by being more polished in the easy markets but by being present in the hard ones is a genuine strategic temperament, not just ambition. The honest critique is that a founder’s appetite for global expansion can outrun the discipline the model demands, and a full-stack processor only wins if the stack stays clean while it sprawls. But the core bet, own the rails end-to-end and earn your moat in the geographies nobody else will service, is one I think is fundamentally right.
