Silverflow, an Amsterdam-based cloud-native card payment processor, has secured a $40 million Series B round as it approaches one billion transactions processed per year. The company says the new capital supports a push toward handling roughly $100 billion in annual payment volume, positioning its platform as an alternative to legacy processing stacks. The round was announced on March 5, 2026.
Deal details
The financing was led by Munich-based investor Picus Capital, with Rabo Investments – Corporate Venturing joining and existing backers Inkef, Global PayTech Ventures, Crane Venture Partners, and Coatue participating. Silverflow said the proceeds will be used to accelerate global expansion, expand product capabilities, and fund a significant hiring plan. The company is targeting a workforce increase of more than 50%, growing from about 85 employees to roughly 120, with an emphasis on engineering and product roles.
Rapid scaling and customer traction
Silverflow reports that over the last two and a half years it has scaled from processing around 180 transactions per day to nearly 1.75 million daily transactions, a pace that underpins its “near-billion” annual run rate. Its client base spans acquiring banks, payment companies, and commerce platforms operating across Europe, North America, and Asia-Pacific, with referenced customers including Deutsche Bank, Bolt, Payabl, and Buckaroo. The company attributes that growth to a cloud-native architecture designed to keep performance stable as volumes and geographic footprint expand.
What Silverflow provides
Founded in 2019 by CEO Anne Willem De Vries alongside Paul Buying and Robert Kraal, Silverflow offers a single-API connection into multiple card networks and selected local debit rails. Media coverage describes the platform as providing direct connectivity to card networks and surfacing enriched data and real-time insights through its APIs for PSPs, acquirers, payment facilitators, and merchants. The company’s feature set highlighted in reporting includes 3D Secure, network tokenisation, direct-to-card payouts, and a dispute-management portal.
Expansion and product roadmap
Geographically, Silverflow plans to deepen its North American presence by strengthening its New York office while further building out operations in Southeast Asia, aligning with its stated focus on North America and APAC. On the product side, the company says it intends to add support for additional card networks, including China UnionPay and JCB, complementing existing scheme connectivity. It also plans to invest in more front-end tools and user interfaces to make its API-driven data easier to use, alongside expanded support for in-store payments.
Investors backing the round framed the opportunity as a modernization cycle in payments infrastructure, where cloud-native processing can replace monolithic systems that slow change and raise integration costs. For Silverflow, the next test will be executing across new regions while broadening network support and extending capabilities toward card-present commerce, without sacrificing reliability at higher scale. If the company sustains its current growth trajectory, it will strengthen its bid to become a long-term processing layer for banks and payment platforms worldwide.
