Two years ago, Kustom didn't exist. The Stockholm-based checkout company spun out of Klarna in 2024, and it's been on an acquisition tear ever since. Its latest move is the largest yet: buying the entire Checkout division of Vipps MobilePay for up to NOK 490 million, roughly $50 million. That's not pocket change for a two-year-old company.

The deal instantly adds more than 3,000 merchants and NOK 7 billion in annual transaction volume to Kustom's platform. It also makes the company a recommended checkout partner across the Nordics' most widely used digital wallet, which counts over 12 million users in Norway and Denmark. For Vipps MobilePay, the sale represents a strategic pivot. The company is doubling down on its core wallet product and stepping away from the checkout wars entirely.

This isn't a typical acqui-hire or a talent grab. It's a full operational absorption. Vipps MobilePay Checkout merchants will be migrated to Kustom's platform on a rolling basis, and the two companies will co-develop payment products going forward.

The headline figure, up to NOK 490 million, includes performance-based components tied to merchant retention and migration success. Kustom funded the acquisition partly through a SEK 367 million investment from Resurs Bank, a Swedish consumer finance company that's now deeply embedded in Kustom's capital stack.

The transaction volume alone tells you something. NOK 7 billion flowing through 3,000 merchants is serious infrastructure. These aren't test pilots or beta customers. They're established Norwegian and Danish e-commerce operations that were running on Vipps MobilePay Checkout as their primary payment rail.

"Our long-term ambition is to revolutionize European commerce," Kamjar Hajabdolahi, Kustom's CEO, said in a statement. "This acquisition cements our leading position in the Nordics and unlocks significant opportunities." That's corporate-speak, sure. But the underlying math is hard to argue with.

For Rune Garborg, CEO of Vipps MobilePay, the logic runs in the opposite direction. His company formed through the 2022 merger of Norway's Vipps and Denmark's MobilePay. The combined entity has 12 million users across the Nordics. That's an enormous consumer base. The question was always whether the company should keep fighting checkout battles against Klarna, Adyen, and now Kustom, or focus entirely on being the wallet that sits inside someone else's checkout.

They chose the wallet. "We face increasing competition from global tech companies," Garborg said. "To compete more effectively, we must sharpen our role as a digital wallet, strengthen distribution through partners and focus fully on the customer experience." Translation: building checkout infrastructure is expensive and distracting when your real asset is consumer trust.

The partnership component of the deal reinforces this. Vipps MobilePay will now recommend Kustom to merchants who want to accept Vipps or MobilePay payments. That's essentially outsourcing the merchant-facing checkout while keeping the consumer relationship intact.

Kustom's origin story matters here. The company was carved out of Klarna's checkout technology in 2024. That gave it a running start on the technical side. What it lacked was scale, merchant relationships, and geographic breadth. The Vipps MobilePay deal addresses all three at once.

The Resurs Bank investment, announced just one day before the Vipps deal, wasn't coincidental. The SEK 367 million gave Kustom both capital and a consumer lending partner. Pair that with Vipps MobilePay's wallet distribution and you've got a company that can offer merchants a full-stack payment experience: checkout, lending, and wallet payments across three Nordic countries.

There's a pattern in European payments right now. Large established players are shedding non-core assets, and younger companies are snapping them up to build scale. TrueLayer bought Sweden's Zimpler. Ramp acquired Stockholm's Billhop. Now Kustom is doing the same with Vipps MobilePay's checkout arm.

The practical impact is straightforward. Over the coming months, merchants currently on Vipps MobilePay Checkout will be migrated to Kustom's platform. Kustom says the transition will be seamless, but anyone who's been through a payment platform migration knows that "seamless" is relative.

The upside for merchants is access to Kustom's broader feature set, including more payment methods and potentially better conversion optimization. The risk is the usual integration friction that comes with any migration.

For the wider Nordic e-commerce landscape, the deal signals consolidation. The number of independent checkout providers in the region is shrinking. Klarna, Adyen, Stripe, and now Kustom are the major players left standing. Smaller operators will face increasing pressure to either specialize or sell.

Hajabdolahi keeps using the word "European" in every public statement. The Resurs Bank funding was explicitly earmarked for European expansion. The Vipps MobilePay deal gives Kustom a playbook for absorbing local payment infrastructure in other markets.

Whether Kustom can replicate this outside the Nordics remains the open question. The company's advantage, its Klarna heritage and deep understanding of Nordic payment behavior, doesn't automatically translate to Germany, France, or Southern Europe. But with NOK 490 million in merchant contracts now on its books and a fresh capital injection behind it, the company has bought itself time to figure that out.

The Nordic payments landscape just got a little smaller. And Kustom just got a lot bigger.
