Banking-as-a-Service 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.

Daniel Kjellén and Fredrik Hedberg didn't set out to build infrastructure. Tink started in Stockholm in 2012 as a consumer personal finance app — an attempt to give Swedish bank customers a cleaner view of their money across multiple accounts. It was a reasonable idea that ran into an unreasonable obstacle: getting reliable, consistent data out of European banks was extraordinarily hard. The technical problem turned out to be more interesting than the consumer product. In 2018 they pivoted, shifted focus entirely to the B2B layer, and started selling the very infrastructure they'd been forced to build for themselves. That pivot proved prescient. The EU's PSD2 directive, which came into full effect in 2019, legally required banks to open their data to authorised third parties — creating the regulatory foundation that open banking platforms needed to operate at scale. Tink had spent years building exactly those bank connections. When the regulation arrived, the company was ready. The platform Kjellén and Hedberg built connects to more than 3,400 banks and financial institutions across Europe, reaching over 250 million bank customers. Through a single API integration, banks, fintechs, and merchants can access aggregated account data, initiate payments directly from customer bank accounts, verify account ownership, and enrich transaction data — without maintaining their own connections to hundreds of separate banking systems with different technical standards and update schedules. Clients include Klarna, PayPal, NatWest, ABN AMRO, and BNP Paribas Fortis. In March 2022, Visa completed the acquisition of Tink for €1.8 billion — one of the largest European fintech acquisitions of that year, and a clear signal of how seriously the global payments industry had come to take open banking infrastructure. Visa's strategic rationale was straightforward: it had failed to acquire Plaid, the US equivalent, after an antitrust challenge, and needed a European open banking capability. Tink gave it 500 employees, 18 European markets, and relationships with over 300 banks and fintechs built over a decade. The founders stayed on as CEO and CTO through the transition, continuing to run Tink as a standalone Visa subsidiary from Stockholm. Both departed in 2025 — Kjellén and Hedberg announced they were building Freda, a new AI-driven legal and compliance technology startup, with the pair describing Tink as "now in better hands than ever." Francois Tornier, Visa's VP of Open Banking, took over as CEO. The product roadmap has continued under Visa ownership, including a 2024 expansion of Tink's open banking platform into the US market.

Lendable is the most valuable European fintech most consumers have never heard of, which is partly by design. Martin Kissinger — German-born, LSE and Oxford, an entrepreneur-in-residence at Rocket Internet before founding his own company — started it in London in 2014 with Victoria van Lennep, Paul Pamment, and Jakob Schwarz, in the dying days of the peer-to-peer lending era. The insight that outlived P2P was structural: don't hold loans on your own balance sheet and don't take retail money — aggregate institutional capital from pension funds and hedge funds, and compete purely on underwriting. Lendable's machine-learning models automate credit decisions end to end, approving personal loans in seconds, and the company takes fees for origination and servicing while the institutions take the credit risk. Asset-light, capital-efficient, and — unusually for the category — profitable early and quietly, a combination that had Sifted profiling it as one of Europe's most secretive fintechs back in 2020. The quiet ended with the numbers. Revenue jumped 90% to £446 million in 2025 with profits more than doubling, and Experian data showed Lendable issued more new consumer credit loans by volume than any other UK lender that year — any bank included — while ranking second in new credit cards issued. A twelve-year-old company with 643 employees out-originating institutions with balance sheets a hundred times its size is the clearest available evidence that consumer credit underwriting is now a data and automation problem, not a branch-network problem. The product range has widened from personal loans into credit cards and car finance, and in July 2026 the company priced its debut public securitisation — a £500 million deal backed by UK personal loans under the Hoxton Consumer Loan Funding programme — opening a cheaper, deeper funding channel alongside its institutional partnerships. The capital story has been correspondingly disciplined: roughly $290 million in equity across its history, a £210 million round led by Ontario Teachers' Pension Plan in March 2022 valuing the company at £3.5 billion, and Goldman Sachs among the backers. The valuation hasn't been retested publicly since — which cuts both ways in a repriced fintech market — and the IPO question follows Lendable around as persistently as it follows Monzo, with nothing filed. Expansion is the current chapter: the US operation established in 2021 is where profits are being reinvested, with Mexico planned next. Kissinger's thesis for why a lender travels better than a neobank is worth noting — personal loans and credit cards are structurally similar across markets, while current-account propositions are deeply local. The honest caveat is the one that applies to every consumer lender that has only grown: Lendable's model has been profitable through a decade that included a pandemic and a rate shock, but unsecured consumer credit is cyclical, and an originator whose volumes now lead the UK market carries UK household credit exposure at scale — mediated to institutional investors, but reputationally and operationally its own. The machine has out-underwritten the banks in benign and bumpy conditions alike; a genuine credit downturn remains the test that separates good models from lucky ones.

Omnius is a European fintech infrastructure player that builds the plumbing for digital finance. Rather than launching consumer apps or chasing trends, the company focuses on giving financial institutions and fintech operators the core technology to move faster. The platform handles payment processing, account management, and the underlying APIs that let banks and non-banks operate at scale without reinventing the wheel. What distinguishes Omnius in a crowded infrastructure market is its pragmatic approach to complexity. European banks still manage legacy core systems alongside new digital channels—a messy, expensive reality most fintech companies ignore. Omnius doesn't fight that; it sits in the middle, connecting old and new, and abstracts the chaos away from the business logic above it. The company targets institutions that need to modernize faster than their technology stacks allow. That includes challenger banks that need banking-as-a-service foundations, traditional banks building new digital channels, and fintech companies that want to scale without owning every layer. It's unsexy infrastructure work—the kind that doesn't generate headlines but quietly powers the financial services layer that consumers interact with. In the European fintech stack, Omnius occupies a critical but overlooked position: the vendor that lets faster companies stay fast, and slower ones move at all.

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.

ClearBank was the first new clearing bank in the UK in more than 250 years. That sentence is doing a lot of work, because the reason there hadn't been one is that clearing — the plumbing that moves money between banks — had settled into the hands of four incumbents whose systems dated to a different era, and every fintech that wanted to offer accounts had to rent access from one of them. ClearBank launched in 2015 to be the alternative: a purpose-built, cloud-native clearing bank with no legacy estate, accessed through a single API, holding client funds at the Bank of England rather than on its own balance sheet. The customer list explains the model better than the description does. TrueLayer, Tide, Chip, Coinbase, Raisin and Wealthify all run on ClearBank — companies that wanted to offer accounts and payments without becoming banks themselves. ClearBank provides the regulated banking layer and the real-time payment rails; the client owns the customer relationship. This is embedded banking delivered by an actual bank rather than middleware, which is the distinction that matters when a regulator asks who is holding the money. The financial trajectory has been unusually disciplined for the category. ClearBank has been profitable since 2022, reported its first full-year pre-tax profit of £18.4 million in 2023, and delivered a third consecutive profitable year in 2025 with group normalised revenue up 34% to £121.6 million. The more significant number is that fee-based income grew 51% and now makes up the majority of revenue — the deliberate pivot away from interest-rate dependency that most banks talk about and few execute. The infrastructure now underpins more than 17 million accounts, and ClearBank UK holds an investment-grade BBB− rating from S&P, rare for a company its age. Europe is the current chapter, and it resolves an old caveat about ClearBank being UK-only. ClearBank Europe N.V., headquartered in Amsterdam and led by Rintse Zijlstra, received a Credit Institution Licence from the European Central Bank under DNB supervision in 2024, backed by more than €70 million of investment. It gives the group euro accounts and payments alongside sterling, with access to TARGET2, SEPA Credit Transfer and SEPA Instant. By the end of 2025 the European business covered 21 EU countries, had opened a Paris branch, and was processing over a million payments a month — real but early, which is the honest way to frame it against a UK operation of 17 million accounts. Mark Fairless succeeded Charles McManus as chief executive.
