Dutch FinTech Silverflow targets international growth as transaction volumes approach one billion annually

May 29, 2026 - 11:00

Silverflow, a Dutch cloud-native payment processing company, is accelerating its post-Series B expansion after signing a new US customer, increasing headcount by more than 20% and moving into new headquarters to support growing global demand.

The move comes just two months after Silverflow closed a €37 million ($40 million) Series B in March, as covered by EU-Startups.

Anne Willem de Vries, co-founder and CEO of Silverflow, says: “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.”

Silverflow’s office move, hiring growth and new US customer sit within a 2026 European payments infrastructure market where capital is still being directed towards platforms reducing fragmentation in payment processing, money movement, embedded finance and AI-enabled transaction workflows.

Approximate disclosed funding across 2026 payments and payments-adjacent rounds totals over €253 million, including Silverflow’s own €37 million Series B.

The largest disclosed comparables are Primer’s €86.2 million Series C and Sokin’s €83 million debt facility, both linked to international expansion and infrastructure scaling, while earlier-stage rounds for SolvaPay, Ralio, finperks and Smartwage show investor interest in narrower infrastructure layers around agentic payments, prepaid systems and regulated digital payment use cases.

The most relevant local comparator is Amsterdam-based Klearly, whose €12 million Series A indicates that Dutch payments startups are also attracting fresh capital in adjacent parts of the stack.

Against that backdrop, Silverflow’s post-Series B expansion is less a standalone milestone than evidence that the company is now moving from funding into execution alongside a broader cohort of European payments infrastructure firms.

“We’ve established ourselves in Europe and have already proven the strength of our platform with customers in markets around the world,” adds Anne. “The next step is continuing to scale internationally and delivering on our mission to become the world’s most trusted payment processor.”

Founded in 2019, Silverflow is a cloud-native solution with a single API to the card networks. Their aim is to use their platform to reduce cost and complexity, while being easy to use and data-rich.

Over the past two and a half years, Silverflow says they have scaled from processing around 180 transactions per day to nearly 2 million – a near ten-thousandfold increase and is now approaching one billion transactions on an annualised basis.

The company’s next target is €85 billion ($100 billion) in annual payment value processed.

That trajectory is being driven by a growing roster of enterprise customers – including Deutsche Bank, Bolt, payabl. and Buckaroo – spanning acquiring banks, payment companies and high-growth commerce platforms across Europe, North America and Asia-Pacific.

Anne adds: “Every hire we make, every square metre 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.”

The Silverflow 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, the company has signed a new US customer and gone live with an existing US client. Silverflow is actively pursuing further growth across the US market while also expanding its presence in Southeast Asia, a region it views as one of the highest-growth and most structurally underserved in global payments.
