Silverflow's Global Push After Nearing 1 Billion Transactions

Jan de Vries · 2026-05-29

Silverflow, a Dutch cloud-native payment processing company, is stepping on the gas after its Series B round. The company just signed a new US customer, boosted its headcount by over 20%, and moved into bigger headquarters to handle all that global demand. This all comes just two months after Silverflow closed a $40 million Series B in March, as covered by EU-Startups. It's a clear sign they're not just resting on their funding—they're putting it to work. ### What the CEO Says About Growth Anne Willem de Vries, co-founder and CEO of Silverflow, puts it simply: "Moving into a new office is one of those moments that makes growth feel real. Six years ago, this team was a fraction of the size it is today. We needed more space, more desks, and more room to build—and that's exactly what we now have. This is what momentum looks like." That momentum isn't just about square footage. It's about the bigger picture in European payments infrastructure.  ### The Bigger European Payments Picture Silverflow's expansion sits inside a 2026 European payments infrastructure market where investors are still pouring money into platforms that cut fragmentation. We're talking payment processing, money movement, embedded finance, and AI-powered transaction workflows. Approximate disclosed funding across 2026 payments and payments-adjacent rounds totals over $274 million, including Silverflow's own $40 million Series B. The biggest disclosed comparables are Primer's $93 million Series C and Sokin's $90 million debt facility—both tied to international expansion and infrastructure scaling. Earlier-stage rounds for SolvaPay, Ralio, finperks, and Smartwage show investor interest in narrower infrastructure layers like agentic payments, prepaid systems, and regulated digital payment use cases. The most relevant local comparator is Amsterdam-based Klearly, whose $13 million Series A shows Dutch payments startups are still attracting fresh capital in adjacent parts of the stack. Against that backdrop, Silverflow's post-Series B expansion isn't just a standalone milestone. It's evidence the company is moving from funding into execution alongside a broader cohort of European payments infrastructure firms.  ### From 180 Transactions to Nearly 2 Million Founded in 2019, Silverflow is a cloud-native solution with a single API to the card networks. Their goal is to reduce cost and complexity while being easy to use and data-rich. Over the past two and a half years, Silverflow has scaled from processing around 180 transactions per day to nearly 2 million—a near ten-thousandfold increase. They're now approaching one billion transactions on an annualized basis. The company's next target is $100 billion in annual payment value processed. That trajectory is driven by a growing roster of enterprise customers, including Deutsche Bank, Bolt, payabl., and Buckaroo. These span acquiring banks, payment companies, and high-growth commerce platforms across Europe, North America, and Asia-Pacific. Anne adds: "Every hire we make, every square foot we add, is a direct response to what our customers are asking of us. They want faster time-to-market, simpler infrastructure, and better data. We can deliver all of that today, at scale, in markets where legacy processors have been a bottleneck for years." ### What's Next for Silverflow The company's product offering is actively expanding. Support for China UnionPay and JCB is in development, extending a network suite that already covers Visa, Mastercard, American Express, Diners, Discover, and several local debit networks. Enhanced in-store payment capabilities and new front-end tooling are also underway. Since announcing its Series B round, Silverflow has signed a new US customer and gone live with an existing US client. They're actively pursuing further growth across the US market. Anne sums it up: "We've established ourselves in Europe and have already proven the strength of our platform with customers in markets around the world. The next step is continuing to scale internationally and delivering on our mission to become the world's most trusted payment processor."
