Merchant acquiring Companies in Europe

Pieter van der Does and Arnout Schuijff had already built and sold one payments company when they sat down in 2006 to start again. The result was Adyen — the name literally means "start over" in Surinamese — and the premise was simple: instead of stitching together the same fragmented payment infrastructure everyone else was using, they would build the whole thing themselves from scratch. That decision, made in an Amsterdam office nearly two decades ago, is still the reason Adyen is different. Most payment companies are assemblers — they buy a gateway here, a processor there, bolt them together and hope for the best. Adyen owns its own technology stack end to end, which means a merchant integrating once gets access to card processing, local payment methods, point-of-sale terminals, and real-time settlement data through a single platform. No middle layers, no reconciliation headaches, no finger-pointing between vendors when something breaks. The client list tells you everything about where Adyen sits in the market. McDonald's, Spotify, Microsoft, LVMH, H&M — these are companies with serious payment volumes and zero appetite for systems that don't work. Adyen became the default choice for enterprises that had outgrown the limitations of traditional payment stacks and needed something that could handle global scale without buckling. Since going public on Euronext Amsterdam in 2018, Adyen has grown into one of Europe's most valuable technology companies, with around 4,300 employees across 23 countries and net revenue of just under €2 billion in 2024. It remains headquartered in Amsterdam and consistently profitable — a combination that's rarer in fintech than it should be. For businesses that treat payments as infrastructure rather than an afterthought, Adyen is the benchmark everything else gets measured against.

Adriaan Mol built Mollie's first backend while living with his parents in the Netherlands in 2004. No investors, no office, no team — just a founder and an idea that small businesses deserved a payment integration that didn't require a team of lawyers and a six-month setup process. He bootstrapped it for over fifteen years before taking outside funding in 2019. By then, Mollie had already grown into one of the most important payment platforms in European e-commerce, entirely on the back of a product that developers actually liked using. The proposition is straightforward: one API, one dashboard, and access to the payment methods that actually matter across Europe. That means iDEAL in the Netherlands, Bancontact in Belgium, Klarna and SEPA Direct Debit everywhere, alongside cards, Apple Pay, and a growing list of local methods that would otherwise require separate integrations and separate acquirer relationships. Mollie handles the compliance, the fraud monitoring, and the settlement complexity. Merchants get a clean interface and a single invoice. For the 250,000 businesses using Mollie today — ranging from Gymshark and Wild to local bakeries and market stalls, as CEO Koen Köppen regularly points out — the appeal is less about feature lists and more about what they don't have to think about. European payments are fragmented by design. Every country has its preferred methods, its own regulatory quirks, its own consumer habits. Mollie's job is to make that invisible. The numbers from 2024 reflect a company that has found its model. Revenue reached €214 million, up 28% year on year, with gross profit growing 30% to €115 million and the company returning to positive EBITDA for the first time since 2018. Mollie raised a total of $940 million in funding and was valued at $6.5 billion following its 2021 Series C led by Blackstone. The most significant recent development is the acquisition of GoCardless in December 2025 — bringing the UK-based direct debit specialist into the Mollie group and substantially expanding its recurring payments and bank transfer capabilities across Europe. Combined, the two companies cover a considerable share of European e-commerce payment infrastructure. Mollie is still headquartered in Amsterdam, with around 900 employees across offices in Ghent, London, Lisbon, Munich, Milan, Paris, and beyond.

SumUp is a payments company built for the merchants traditional providers never bothered with. Founded in 2012 and headquartered in London, it sells low-cost card readers and point-of-sale hardware to small businesses — market traders, cafés, hairdressers, tradespeople — who could never justify the monthly fees, multi-year contracts, and cumbersome terminals that legacy processors demanded. The core proposition has barely changed since launch: buy a card reader outright for a modest one-off price, pay a small percentage per transaction, and sign nothing. That model has scaled a long way past its origins. SumUp now serves more than 4 million merchants across roughly 35 markets, employs around 4,000 people, and was valued at about €8 billion in a 2022 round led by Bain Capital. In 2024 it raised a €1.5 billion private credit facility led by Goldman Sachs, and it has been weighing a stock market listing that could value it as high as $15 billion. The more significant shift is that SumUp is no longer a card reader company. Through a run of acquisitions — Payleven, the e-commerce platform Shoplo, the core banking provider Paysolut, POS software firm Tiller, and the US loyalty startup Fivestars — it has assembled a full financial stack for micro-businesses: a business account and card, invoicing, an online store, loyalty tools, self-service kiosks, and SDKs for developers who want to embed card acceptance in their own products. The ambition is to be the only software a small merchant needs to run their business. That leaves SumUp in an unusual competitive position. On hardware and in-person payments it faces Square, Zettle, and Dojo; as a broader business platform it edges toward Stripe, Mollie, and Revolut Business. Its defensibility rests on the segment most of the industry finds too small to serve properly — the micro and nano merchants that make up the long tail of European commerce.

Nexi is what happened when Italy decided to build a payments champion. The company's roots run through decades of bank-owned card infrastructure — the CartaSi and ICBPI lineage that processed Italian card payments on behalf of the banking system — before private equity firms Advent, Bain, and Clessidra reshaped it into a company and took it public on Borsa Italiana in 2019. Then came the two deals that defined it: the merger with SIA, Italy's interbank payments infrastructure, and the acquisition of Denmark's Nets, both closed in 2021. The result was "The European PayTech" — a group operating in more than 25 countries with around 9,200 employees, spanning merchant acquiring, card issuing for banks, and national payment infrastructure from Italy to the Nordics to Poland, where Nets' acquisitions of Przelewy24 and Dotpay sit inside the group. The strategy was scale through consolidation, and for a while the market believed in it. It no longer does, and March 2026 was the moment that became undeniable. Nexi's full-year 2025 results — revenue of €3.58 billion, EBITDA of €1.9 billion, growth of just 2.1% — arrived with a €3.7 billion writedown on previously acquired businesses, chiefly Nets, and guidance that 2026 would be flat, with growth not returning until 2028. The stock fell more than 20% in a day to a record low. CEO Paolo Bertoluzzo's framing to investors was unusually candid for the genre: Nexi was transitioning from a growth company to one that produces steady cash flows — "you don't have to believe we can go to the moon" — with a dividend hiked 20% and €1.1 billion in shareholder returns planned through 2028 as the consolation. His defence of the writedown was equally frank: Nexi bought companies at high prices, but paid in shares that were then worth six times their current value. The ownership structure completed its own transition in early 2026. Advent and Bain, the private equity firms that built and listed the company, sold their remaining stake in February — leaving Hellman & Friedman and CDP, the Italian state investor, as the two anchor shareholders at roughly a fifth each. The parallel with Worldline is hard to miss: Europe's two great payments roll-ups of the 2019–2021 era have both ended the cycle written down, growth-challenged, and anchored by state-linked capital — Nexi without the compliance scandal, which is a meaningful distinction, but with the same underlying lesson about buying growth with expensive shares. CVC explored a bid in 2024, sending the shares up 19% in a day; nothing came of it, though the episode established that the company is viewed as acquirable. Leadership turned over with the strategy: Bernardo Mingrone, Nexi's long-serving finance chief, succeeded Bertoluzzo as CEO in 2026, presenting his first half-year results in July. The growth initiatives under way are real if unglamorous — Zippay, a person-to-person payment service built on Nexi infrastructure launching in Ireland with AIB, Bank of Ireland, and PTSB; integration of the European wallet Wero into German e-commerce; a Visa partnership on managed card issuing for German banks; and the €105 million acquisition of Banca Popolare di Sondrio's merchant book, continuing the model of buying banks' payment operations that built the company. Nexi remains one of Europe's largest payment processors and the default infrastructure of Italian digital payments. The question its own guidance poses is whether that is a platform for renewed growth from 2028, or simply a very large utility returning cash to patient shareholders. The current share price says the market has priced the utility.

Polish online payment processing has multiple credible operators competing for similar market segments, and the differentiators between them often come down to operational reliability, merchant service quality, and integration depth with the specific platforms that Polish e-commerce builders use. Tpay was founded in 2010 to compete in that market, building a payment gateway and processing platform serving Polish online merchants across the full range of payment methods their customers expect — instant bank transfers, BLIK, cards, deferred payment options. The company has built a substantial merchant base across Polish e-commerce, with particular strength in segments where its operational reliability and customer service have built durable merchant relationships. Tpay operates in a market where the established players date back to the late 1990s and early 2000s, requiring newer entrants to compete on dimensions where their operational architecture and product approach can offer genuine advantages over the legacy infrastructure that defines older platforms. The maturation of Polish e-commerce through the 2010s and 2020s has continued to expand the addressable market faster than the established operators have absorbed it, leaving room for platforms like Tpay to build sustainable positions even as the overall sector consolidates.

Dotpay was one of the pioneer names of Polish online payments — a Kraków company from the early 2000s that built the pay-by-link infrastructure connecting Polish e-commerce to the country's bank-transfer-first payment culture, long before international processors took Poland seriously. Alongside eCard, its card-acquiring counterpart, it formed the Dotcard group that served tens of thousands of Polish merchants through the first two decades of the country's e-commerce growth. Today, Dotpay exists as a brand history rather than an operating company, and the sequence matters for anyone researching it. In January 2019 the Nordic payments group Nets acquired Dotcard — Dotpay and eCard together. Later that year, regulators approved a joint holding, P24 DotCard, combining the Nets-owned Dotpay/eCard with Przelewy24, Poland's largest online payment operator, with Nets holding 51% and Przelewy24 founder Piotr Kurczewski 49%. Nets itself was then absorbed into Italy's Nexi in 2021, carrying the whole Polish structure into the "European PayTech." The consolidation proceeded in stages: on 1 April 2021, Dotpay Sp. z o.o. was formally merged into PayPro SA, the company behind Przelewy24, and in the final phase merchant accounts were migrated off the Dotpay platform entirely — the company's own announcement was titled, plainly, "Dotpay is now Przelewy24." By 2026, Nexi's Polish operations are structured around Przelewy24 and Polskie ePłatności under shared group management, with Dotpay no longer named as a separate entity. For merchants and researchers, the practical answer is simple: Dotpay's services, customers, and infrastructure live on inside Przelewy24, within the Nexi Group. The brand that helped build Polish e-commerce payments was ultimately consumed by the consolidation wave it helped make Poland attractive to.
