Silverflow Accelerates US Expansion with $40M Series B and New Sales Leadership

Silverflow is accelerating its North American expansion with the appointment of Jay Diamonon as VP of Sales, following a $40 million Series B funding round. For fintech professionals, this move signals a direct challenge to legacy US processing infrastructure by a cloud-native player now processing $40 billion in annual volume and two million daily transactions.

What was announced

Silverflow has appointed Jay Diamonon as VP of Sales to spearhead its commercial growth across North America. Diamonon brings two decades of experience in payments and financial services, having previously held sales leadership positions at Adyen and BBVA. His background also includes financial planning and analysis roles at Continental Airlines and Air Liquide. This strategic hire is a central component of Silverflow’s broader international push, supported by a $40 million Series B funding round announced in March 2026. Led by Picus Capital, the round included participation from Rabo Investments – Corporate Venturing, Inkef, GPT, Crane, and Coatue. The capital is earmarked for product development, international operations, and a planned 50% increase in the company’s global workforce.

Silverflow’s expansion into the US market targets acquiring banks, payment companies, and commerce platforms seeking modern alternatives to legacy infrastructure. The company’s growth trajectory is significant; it currently processes $40 billion in annual volume and handles 2 million transactions per day. This represents a massive scale-up from March 2026, when it reported 1.75 million daily transactions, and a stark contrast to the 180 transactions per day it processed just two and a half years prior. The firm is now prioritizing North America alongside further expansion efforts in the Asia-Pacific region.

"The US payments market is highly competitive and businesses need to be able to adapt quickly as customer expectations and the way people pay continue to evolve. But that becomes difficult when you’re working with processing infrastructure that wasn’t built for the pace or complexity of modern payments."

The companies involved

Headquartered in Amsterdam, Silverflow provides a cloud-native payment processing platform designed to replace the aging technology stacks that many financial institutions still rely on. Unlike traditional processors that often operate on decades-old systems, Silverflow offers a single API connection to card networks, providing acquirers and payment service providers with direct access to data and more flexible settlement options. The company has rapidly established itself as a modern alternative in the global payments ecosystem, backed by a diverse group of venture capital firms. Picus Capital, which led the recent Series B round, is a global venture capital firm that focuses on technology companies with long-term growth potential. Other key backers include Rabo Investments, the corporate venturing arm of the Dutch banking giant Rabobank, and Crane, a firm known for its investments in deep-tech and enterprise software. Silverflow’s cap table also includes Inkef, GPT, and Coatue, reflecting a broad base of institutional support for its mission to modernize the backend of the payments industry. As the company moves deeper into the North American market, it enters a space dominated by established incumbents but ripe for disruption by cloud-first architectures.

What FF News has reported before

FF News has closely tracked Silverflow’s recent partnership activity and its role in the evolving acquiring landscape. In September 2026, the company collaborated with Hypergate to launch a cloud-native acquiring solution for financial institutions, aimed at streamlining the merchant onboarding process. This followed a move to accelerate European payment processing through an expanded partnership with Griner. Additionally, Silverflow’s technology has been instrumental in helping firms like Finsei, which recently launched integrated card acquiring to simplify merchant payment ecosystems. These developments highlight Silverflow’s strategy of embedding its processing power within the platforms of other fintech providers to drive volume and market share.

What this means

The US payments market is currently at a crossroads where the resilience of legacy systems is being tested by the demand for real-time data and cross-border flexibility. Silverflow’s aggressive push into North America puts significant pressure on established US processors that have historically relied on "wrapped" legacy tech rather than true cloud-native builds. The appointment of a sales leader from Adyen suggests a strategy focused on high-growth, tech-savvy merchants who value transparency over traditional bundled services. The central question for the sector is whether European-born cloud processors can overcome the localized complexities of the US banking system fast enough to unseat incumbents before they modernize their own stacks.
