Silverflow Closes $40 Million Series B As It Nears One Billion Transactions Annually
Silverflow, the cloud-native payment processing company, has successfully closed a $40 million (€37 million) Series B funding round, marking a major milestone as the company approaches one billion transactions processed annually.
The significant investment was led by Munich-based deep-tech investor Picus Capital, with participation from Rabo Investments – Corporate Venturing, and existing investors, Inkef, GPT, Crane and Coatue. This European-led capital injection will be used to solidify Silverflow’s position as the new standard in payment processing, accelerating its global expansion, enhancing its product suite and funding a massive increase in its global workforce by more than 50%.
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of Silverflow, said: “This investment is a clear validation that the market is ready to move past the ‘legacy drag’ of outdated systems.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.”
Over the past two and a half years, Silverflow has grown from processing around 180 transactions per day to almost 1.75 million daily, underlining both the speed of adoption and the resilience of its cloud-native architecture. Customers span acquiring banks, payment companies, and high-growth commerce platforms operating across Europe, North America and Asia-Pacific, including Deutsche Bank, Bolt, Payabl. and Buckaroo, among others.
To support this momentum, Silverflow will increase its global workforce by more than 50%, expanding from 85 to approximately 120 employees, with a particular focus on software engineering and product development. Geographically, the capital will accelerate Silverflow’s expansion in North America, bolstering the New York office, and further establishing its presence in Southeast Asia.
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.”
On the product front, Silverflow will build out support for additional card networks, such as China UnionPay and JCB. This complements its existing business with Visa, Mastercard, American Express, Diners, Discover and some local debit networks. It will also invest in new front-end tools and UIs to make its data-rich APIs more accessible, and will expand its end-to-end offering to provide enhanced support for in-store payments.
