Adyen

🇳🇱 Netherlands

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.

Klarna

🇸🇪 Sweden

Three Stockholm School of Economics students pitched an idea at a university entrepreneurship competition in 2005: let shoppers receive goods before they pay, and put the credit risk on the merchant side. The pitch finished last. They built it anyway. Sebastian Siemiatkowski, Niklas Adalberth, and Victor Jacobsson launched what was originally called Kreditor, later renamed Klarna, and spent the next two decades turning that rejected idea into one of Europe's most recognised fintech brands. The core insight held up: millions of people would rather split a purchase into three instalments than reach for a credit card, and merchants would pay for the privilege of offering that option because it reduces cart abandonment and increases average order values. Klarna grew from a Swedish checkout button into something considerably more complex. It now holds a banking licence in Sweden, offers savings accounts, issues its own card, and operates across more than 45 markets with around 93 million active consumers and 675,000 merchant partners at the end of 2024. The US, which Klarna entered in 2015, has become its largest market by revenue, a fact the company underlined by listing on the New York Stock Exchange in September 2025 under the ticker KLAR, raising $1.37 billion at IPO. The financial trajectory has been bumpy. Klarna reported net income of $21 million in 2024, a return to profitability after a bruising 2022 that included an 85% valuation cut and significant layoffs that reduced headcount from over 7,000 to around 3,400. What survived the restructuring was a leaner company with $2.81 billion in revenue and a clearer strategic direction: AI. Klarna's partnership with OpenAI produced a customer service assistant it claims handles the equivalent of 700 full-time agents, and generative AI now manages roughly two-thirds of customer chats. The honest assessment of where Klarna sits today: it's no longer purely a BNPL provider and it's not quite a bank. It's somewhere in between, a consumer finance platform that knows more about your shopping behaviour than your bank does, and is betting that's worth a lot.

Fourthline

🇳🇱 Netherlands

Fourthline didn't start as a KYC company. It started as a payment institution. Krik Gunning and Chris van Straeten founded Safened in Amsterdam, licensed by the Dutch Central Bank as a regulated payment provider. As Safened onboarded its own customers, it built identity verification technology capable enough that other banks and fintechs started asking to use it directly. The demand was real and growing — digital financial services were expanding rapidly but compliance infrastructure hadn't kept pace. In 2019 Gunning and van Straeten spun the KYC operation out as a standalone company and renamed it Fourthline. The name refers to compliance being the fourth line of defence in financial crime prevention — after business operations, risk management, and internal audit. It's a deliberately serious framing for a company that treats KYC not as a box to tick but as a technical problem worth solving properly. While many identity verification providers offer generic document checks, Fourthline built its platform around the regulatory requirements of Europe's strictest financial supervisors — the kind of compliance depth that a neobank launching in Germany or a broker entering the Netherlands actually needs to satisfy its regulator, not just its legal team. The platform covers the full KYC and AML stack through a single API: document verification, biometric checks with liveness detection, AML and sanctions screening, risk scoring, proof of address, and ongoing customer monitoring throughout the customer lifecycle. The modular architecture means regulated institutions can pick the components they need rather than buying a fixed bundle — a practical advantage for fintechs that need identity verification at onboarding but different monitoring requirements at scale. The client list is a reasonable proxy for the quality of the product. Fourthline verifies identities for N26, Qonto, Trade Republic, flatexDEGIRO, Scalapay, Shine, and Bitpanda — regulated financial businesses across Europe that operate under strict supervisory scrutiny and cannot afford onboarding failures. The company employs around 225 people and has raised approximately $70 million in funding, primarily from Finch Capital. In March 2026 Fourthline appointed Paul Stoddart as CEO, replacing co-founder Krik Gunning who moved into an advisory role after leading the company since its founding. The timing coincides with a significant regulatory tailwind: the EU's new Anti-Money Laundering Regulation comes into force in July 2027, substantially raising compliance requirements for financial institutions across Europe and expanding the addressable market for precisely the kind of infrastructure Fourthline has spent six years building.

Tink

🇸🇪 Sweden

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.

Checkout.com

🇬🇧 United Kingdom

Checkout.com is a global payments infrastructure company that builds the plumbing beneath the surface of e-commerce. While most payment processors still operate like legacy banking rails, Checkout.com has constructed a single API that connects directly to card networks, acquiring banks, and alternative payment methods—eliminating the middlemen that slow everything down. The platform processes payments in over 150 currencies across 195 countries, handling everything from straightforward card transactions to complex multi-currency settlements for merchants operating at scale. What sets it apart in Europe and beyond is its refusal to be a typical payment gateway: instead of asking merchants to adapt to the network, Checkout.com adapts the network to the merchant. Founded in 2012 by Guillermo Gutiérrez García-Ceballos, the company has grown from a London-based startup into a critical piece of infrastructure for enterprises, fintechs, and marketplaces that need orchestration at the transaction level. It competes with traditional acquirers and modern payment platforms by combining the reliability of legacy banking with the speed and flexibility developers expect. In the fragmented European payments landscape, Checkout.com has become indispensable for companies that refuse to compromise on latency, coverage, or control. The company represents a fundamental shift in how payments should work: less about choosing between payment methods and more about making payments invisible.

Payhip

🇬🇧 United Kingdom

Payhip lets creators and small businesses sell directly to their audience without the usual gatekeeping. It's a all-in-one commerce platform that handles digital products, physical goods, subscriptions, and memberships—essentially a Shopify alternative built for creators who want simplicity and fair pricing. The platform lives in that sweet spot between marketplace and self-hosted store. You upload your product, set your price, share a link, and start selling. No approval process, no middleman deciding what you can or can't do. Payhip takes a percentage of each sale rather than charging upfront fees, which resonates with bootstrapped creators and solopreneurs who don't have predictable revenue yet. What sets Payhip apart is its lightness. While traditional payment processors demand integration work and setup headaches, Payhip is deliberately frictionless—you can be live within minutes. It also gives sellers control over their own affiliate networks and customer relationships, something most platforms charge extra for or restrict. In the crowded world of creator monetization tools, Payhip occupies the pragmatic middle: more powerful than a simple payment link, simpler than a full ecommerce platform, and designed specifically for people who want to sell without becoming a software engineer. It's quietly influential in how independent creators think about direct sales.

Yapily

🇬🇧 United Kingdom

Yapily sits at the intersection of open banking and embedded finance, building the plumbing that lets fintech companies and enterprises tap into banking data and payments without reinventing the wheel. Founded in 2016, the London-based company operates as an API infrastructure layer—connecting to banks across Europe and beyond to unlock account information, payment initiation, and consent management at scale. What makes Yapily different is how it abstracts away the complexity of working with hundreds of banks and their inconsistent technical standards. Rather than forcing developers to build individual integrations for each bank's API, Yapily provides a unified interface that normalizes everything. It's the translator between your app and the messy reality of legacy banking infrastructure. The company operates in the B2B2C space, partnering with fintechs, neobanks, and enterprise software providers who need banking connectivity but lack the resources to build it themselves. Their customer base spans lending platforms, wealth apps, accounting software, and payment orchestration layers—essentially anyone whose product benefits from real-time access to customer bank accounts or the ability to initiate payments. Yapily's positioning is deliberately unsexy: they're infrastructure, not consumer-facing. But that's precisely the point. In a landscape crowded with consumer fintechs chasing headlines, Yapily has built a quiet, profitable business serving the builders themselves. They're to open banking what Stripe is to payments—the backbone that lets innovation happen faster.

Payhawk

🇧🇬 Bulgaria

Most companies still manage corporate spending the way they did a decade ago—expense reports, manual reconciliation, scattered receipts. Payhawk has built something radically simpler: a unified spending platform that gives finance teams complete visibility into every company transaction, from the moment it's authorized to the moment it's reconciled. The platform combines physical and virtual cards, automated expense management, and real-time spend controls in a single dashboard. What sets Payhawk apart in the crowded corporate finance space is its refusal to compromise on user experience. Employees aren't fighting clunky interfaces or wrestling with legacy systems. Instead, they get an intuitive mobile app that feels like personal fintech, while finance teams gain the analytical firepower to actually manage policy, catch fraud, and optimize spending patterns. The company treats visibility not as a nice-to-have but as the foundation of control. In Europe's SME and mid-market space, where most alternatives still rely on outdated card programs or disconnected software suites, Payhawk's integration of issuance, spend management, and analytics represents a meaningful shift. The company has quietly built something that enterprises have wanted for years: a spending platform that doesn't require compromise between employee experience and financial governance. For finance leaders tired of spreadsheets and reactive reporting, it's become the natural choice.

Anaxago

🇫🇷 France

Anaxago is a European investment platform that democratizes access to private market deals, letting retail investors back startups and SMEs that would normally require deep pockets and insider connections. The platform sidesteps the gatekeeping that has long defined venture capital, offering curated equity stakes in growth-stage companies across tech, real estate, and other sectors. Founded in 2014, it operates across multiple European markets and has processed hundreds of millions in investments, positioning itself as a bridge between ambitious entrepreneurs and everyday investors seeking portfolio diversification beyond public markets. What sets Anaxago apart is its focus on transparency and accessibility. Rather than opaque fund structures or minimum investment requirements that exclude ordinary savers, it lets users invest from relatively modest amounts while maintaining rigorous due diligence on every deal. The platform handles the mechanics of investment management, shareholder rights, and secondary market liquidity—functions that typically require armies of lawyers and compliance teams. It's part of a broader shift toward democratized finance, where technology makes previously exclusive opportunities available to anyone with capital and appetite for risk. In the European fintech landscape, where crowdfunding and alternative investment platforms have proliferated, Anaxago has carved out credibility through regulatory compliance, deal flow quality, and a genuine commitment to investor protection. It represents how fintech can unbundle traditional wealth management, making private market exposure a normal part of retail investing rather than a privilege reserved for the wealthy.

MoonPay

🇬🇧 United Kingdom

MoonPay sits at the intersection of crypto and traditional finance, offering on and off-ramps that let people move money between their bank account and crypto wallets with minimal friction. Founded in 2018, the London-based company has quietly become one of Europe's most important infrastructure plays in the emerging crypto economy, handling billions in transactions across more than 150 countries. What sets MoonPay apart is its unglamorous but essential positioning: it's not trying to be a crypto exchange or a trading platform. Instead, it's the plumbing layer that makes crypto accessible to ordinary people. You buy crypto through MoonPay the same way you'd buy a digital service—seamless, compliant, and fast. The company operates with full EU regulation, holding licenses across multiple jurisdictions while maintaining the kind of compliance rigor that traditional banks expect. MoonPay's API-first approach means startups, wallets, and even traditional fintech apps can embed crypto purchasing directly into their user experience. This white-label capability has attracted partnerships with everyone from music platforms to gaming studios. The company has raised substantial funding and is valued at over a billion dollars, a testament to how critical crypto infrastructure has become. In a market obsessed with trading speculation and yield farming, MoonPay represents something more fundamental: the normalization of crypto as a payment asset class. It's doing for cryptocurrency what Stripe did for online payments—removing the technical and regulatory barriers that kept it confined to specialists.
