Amsterdam-based payment processor Silverflow has secured $40 million in Series B funding as it moves closer to processing one billion transactions annually. The round was led by Picus Capital, with participation from Rabo Investments – Corporate Venturing and existing investors Inkef, Global PayTech Ventures, Crane Venture Partners and Coatue.
The funding will fuel Silverflow’s next growth phase, helping expand its global presence, strengthen its technology platform and increase its workforce as demand for modern payment infrastructure rises.
Silverflow plans to expand network compatibility further by adding support for China UnionPay and JCB. The company will also invest in new user interfaces and tools designed to make its data-rich APIs easier to navigate. In addition, it plans to expand its capabilities to provide stronger support for in-store payment processing, complementing its existing digital infrastructure.
Built by payment industry veterans
Founded in 2019, Silverflow was established by a team deeply rooted in the Dutch fintech ecosystem. Its founders bring extensive experience in payment infrastructure and large-scale transaction processing. CEO Anne Willem de Vries previously worked at Adyen, where he led card acquiring and processing initiatives, including launching payment processing operations in the United States.
Chief Business Development Officer Robert Kraal also brings significant industry experience, having served as COO at Adyen between 2010 and 2014. Earlier in his career he held leadership roles at Bibit and later worked at Google. The company’s Chief Technology Officer, Paul Buying, is a technical entrepreneur and founder of the translation platform Livewords.
From dozens of payments to millions a day
Traditional payment systems often involve layers of intermediaries and fragmented technology, slowing innovation and limiting access to real-time data. Silverflow addresses this problem through a cloud-native architecture designed specifically for modern digital commerce. Instead of patching together legacy systems, the company built its technology from the ground up to support large-scale payment volumes with flexibility and transparency.
The growth trajectory of Silverflow has been rapid. Just over two years ago, the platform handled around 180 transactions per day. Today, it processes almost 1.75 million daily transactions, putting the company on course to handle about $100 billion in annual payment volume. This momentum reflects the challenges faced by many financial institutions relying on outdated infrastructure.
A platform connecting directly to card networks
At the centre of Silverflow’s offering is a unified platform that connects payment providers directly to global card networks through a single API. This approach simplifies integrations while providing deeper transaction insights for banks, acquirers and payment companies.
The system already supports major networks including Visa, Mastercard, American Express, Discover and Diners Club International alongside various local debit schemes.
Looking ahead
Customers already include organisations across banking, fintech and commerce platforms such as Deutsche Bank, Bolt, Payabl and Buckaroo.
With a cloud-native platform, direct network connections and strong industry roots, Silverflow is positioning itself as a modern alternative to legacy payment processing systems powering global commerce.
Anne Willem De Vries, CEO and Co-founder of Silverflow, said: “This investment is a clear validation that the market is ready to move past the ‘legacy drag’ of outdated systems. 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. It’s not just about raising money – It’s about having the resources to build the infrastructure that helps our customers, including acquiring banks, payment companies and commerce platforms, to move faster and grow bigger.
“We’re empowering our customers to simplify complexity, accelerate time-to-market and achieve exponential revenue growth. This investment confirms that our focus on un-fragmenting the global payments ecosystem is the right strategy for every company aiming for financial stability and global scale,” he continued.
Florian Reichert, Partner at Picus Capital, said: “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. Its incredible growth rate, customer momentum and more importantly customer feedback, now approaching one billion transactions processed annually, demonstrate the urgent market need for a modern processor. After working with the team over the past years, we at Picus are proud to lead this Series B round and support Silverflow’s ambitious goal to become the most trusted processor in the world.”
Floris Onvlee, Director Corporate Venturing of Rabo Investments, said: “As an EU-based investor, we’re proud to support Silverflow as an European champion to continue its global expansion. We strongly believe that Silverflow can enable banks and other financial institutions to offer a competitive payment solution from a tech perspective.”
