Key Takeaways

1. Silverflow closed a $40 million (€37 million) Series B funding round led by Munich-based deep-tech investor Picus Capital, with participation from Rabo Investments and existing backers Inkef, GPT, Crane, and Coatue.
2. Transaction volume surged from 180 per day to nearly 1.75 million daily over the past two and a half years, with the company now approaching one billion transactions processed annually.
3. The capital will fuel a 50%+ workforce expansion (from 85 to approximately 120 employees), geographic growth into North America and Southeast Asia, and support for additional card networks including China UnionPay and JCB.

Quick Recap

Amsterdam-based Silverflow, the cloud-native payment processing company, officially announced on March 5, 2026, the close of its $40 million Series B funding round. The round was led by Picus Capital and joined by Rabo Investments – Corporate Venturing, alongside existing investors. The announcement signals a critical inflection point for a company that has grown from a niche European startup into a globally expanding payment infrastructure provider approaching $100 billion in annual processing volume.

From 180 Daily to Nearly One Billion Yearly

The numbers behind Silverflow’s growth tell a compelling story. Just two and a half years ago, Silverflow was processing roughly 180 transactions per day. Today, that figure stands at nearly 1.75 million daily, putting it on pace to cross the one billion annual transactions threshold. This trajectory validates the company’s bet that acquiring banks, payment service providers, and commerce platforms are hungry for a modern, cloud-native alternative to the legacy processing systems that have dominated the industry for decades.

Silverflow’s platform connects directly to card networks like Visa and Mastercard through a single API, eliminating layers of intermediaries that add cost and complexity. Features include direct-to-card payouts, network tokenization, 3D Secure, and a dispute management portal. The company plans to extend support to China UnionPay and JCB, while also investing in new front-end tools and UIs to make its data-rich APIs more accessible to customers.

CEO and co-founder Anne Willem De Vries framed the raise as more than just capital. “This investment is a clear validation that the market is ready to move past the ‘legacy drag’ of outdated systems,” he stated. “We’re the only cloud-native company targeting this specific area, and this capital will ensure we cement our position as the new standard in payment processing globally”.
​

Geographically, the investment supports expansion through Silverflow’s New York office and a further push into Southeast Asia. The workforce is expected to grow from 85 to approximately 120 employees, with hiring focused on software engineering and product development.

The Legacy Payments Problem

The global payments infrastructure market remains dominated by monolithic systems built decades ago. Picus Capital partner Florian Reichert described the landscape bluntly: “The payments infrastructure market is defined by monolithic, slow systems that stifle innovation. Silverflow has proven that a cloud-native, single-API approach is not just an alternative, but the inevitable evolution”.​

Stripe processed approximately $1.4 trillion in total payment volume in 2024, growing 38% year-over-year, while Adyen handled around €1.29 trillion with a 33% annual growth rate. These giants serve merchants directly. Silverflow operates at a different layer: it serves the acquiring banks and payment service providers (PSPs) that sit between merchants and card networks. This B2B infrastructure play positions Silverflow as a supplier to the ecosystem rather than a direct competitor to consumer-facing processors.​

Founded in 2019 by Robert Kraal, Anne Willem De Vries, and Paul Buying, the company has now raised over $76 million to date, building on a $16.3 million round led by Global Paytech Ventures at the end of 2023.

Competitive Landscape

While Silverflow occupies a specialized niche in acquirer-side payment processing, it competes with other cloud-native and next-generation payment infrastructure companies. CLOWD9, a London-based startup founded in 2021, operates as the world’s first cloud-native, decentralized issuer processing platform. Gr4vy, a San Mateo-based company, provides cloud-native payment orchestration for enterprise merchants with total funding of approximately $27.2 million.

Silverflow holds the strongest position in acquirer-side processing with the most capital raised and enterprise client traction, including a major banking name like Deutsche Bank. CLOWD9 differentiates on the issuer side of the equation with a decentralized model, while Gr4vy targets a different segment entirely: payment orchestration for merchants rather than infrastructure for acquirers.

Techno Trenz’s Takeaway

I think this is a big deal, and here is why. Silverflow is not trying to be the next Stripe or Adyen. It is going after the plumbing beneath those companies: the aging, often decades-old processing infrastructure that acquiring banks and PSPs still rely on. In my experience covering fintech funding rounds, the ones that genuinely matter are those where the growth metrics back up the story.

Going from 180 transactions a day to nearly 1.75 million daily is not marketing spin; that is real adoption from serious institutions like Deutsche Bank. I generally prefer to watch how a company deploys capital rather than just how much it raises, and Silverflow’s plan to expand into Southeast Asia and North America while deepening its product with UnionPay and JCB support tells me the leadership has a clear roadmap.
