Cloud-native payment processing firm Silverflow has raised $40 million (€37 million) in a Series B funding round as the company approaches one billion transactions processed annually and prepares for a major global expansion.
The investment round was led by Picus Capital with participation from Rabo Investments alongside existing investors including Inkef, Crane Venture Partners, Coatue Management and Global PayTech Ventures.
The funding will be used to accelerate Silverflow’s international growth, expand its product capabilities and significantly increase its global workforce as the company seeks to modernise payment infrastructure traditionally dominated by legacy systems.
Founded to modernise the payment processing layer used by banks and fintech companies, Silverflow positions itself as the first fully cloud-native platform designed specifically for card networks.
Anne Willem De Vries, chief executive and co-founder of Silverflow, said the latest funding reflected a growing shift in the payments industry away from older processing technology.
“This investment is a clear validation that the market is ready to move past the legacy drag of outdated systems,” he said.
“We’re the only cloud-native company targeting this specific layer of the payments ecosystem. This capital ensures we can cement our position as the new global standard for payment processing.”
Unlike traditional payment processors that rely on decades-old infrastructure, Silverflow’s technology is built entirely in the cloud, allowing banks and payment providers to connect through a single API rather than a patchwork of systems.
The company says this architecture allows customers to launch new payment products faster, simplify operations and scale internationally without the technical complexity associated with legacy payment platforms.
Silverflow’s growth over the past two years has been particularly striking. The company reports that transaction volumes have expanded dramatically since its early commercial rollout.
Just two and a half years ago, the platform processed around 180 transactions per day. Today that figure has climbed to almost 1.75 million daily transactions, highlighting both the rapid adoption of its technology and the scalability of its cloud-based infrastructure.
At its current trajectory, Silverflow is approaching one billion transactions annually and expects to soon process more than $100 billion in payment volume each year.
The platform’s client base includes acquiring banks, payment companies and fast-growing digital commerce platforms across Europe, North America and Asia-Pacific.
Among its customers are global financial institutions and fintech players including Deutsche Bank, Bolt, Payabl and Buckaroo.
The new capital will support a major expansion of Silverflow’s workforce as the company ramps up engineering and product development.
Silverflow currently employs around 85 staff, but plans to grow its global team to approximately 120 employees, representing an increase of more than 50 per cent.
Recruitment will focus heavily on software engineering, product design and payments infrastructure specialists, areas considered critical as the company scales its technology platform.
Geographically, Silverflow intends to accelerate its international presence in several key markets.
In North America, the company will expand its operations in New York, strengthening relationships with acquiring banks and global commerce platforms.
At the same time, the firm plans to deepen its footprint in Southeast Asia, where digital payments adoption is growing rapidly and demand for modern processing infrastructure continues to rise.
Investors say the payments infrastructure market is undergoing a major transformation as financial institutions look to replace outdated systems with cloud-based alternatives.
Florian Reichert, partner at Picus Capital, said Silverflow’s growth demonstrated a strong market demand for modern processing solutions.
“The payments infrastructure market is dominated by monolithic, slow systems that stifle innovation,” he said.
“Silverflow has proven that a cloud-native, single-API architecture is not just an alternative but the inevitable evolution. The company’s growth and customer adoption show that the market urgently needs a modern processor.”
Floris Onvlee, director of corporate venturing at Rabo Investments, added that the investment also supports the emergence of European fintech champions capable of competing globally.
“As an EU-based investor, we’re proud to support Silverflow as a European technology leader as it expands worldwide,” he said.
In addition to geographic expansion, Silverflow plans to broaden the range of card networks supported by its platform.
The company already integrates with major global card schemes including Visa, Mastercard, American Express, Discover and Diners Club International.
Following the Series B investment, Silverflow plans to add support for additional networks such as China UnionPay and JCB.
The company will also introduce new user interfaces and front-end tools designed to make its data-rich API infrastructure easier for developers and financial institutions to use.
These enhancements will support new capabilities across both online and in-store payments, expanding Silverflow’s role across the full payment transaction lifecycle.
Silverflow’s long-term ambition is to simplify what it describes as the fragmented global payments ecosystem, where banks and fintech companies often rely on a complex mix of processors, gateways and card network integrations.
By providing a single cloud-native processing layer, the company hopes to enable financial institutions to launch new payment capabilities more quickly while improving reliability and transparency.
For De Vries, the latest funding round represents not just financial backing but validation of the company’s strategy.
“It’s not just about raising capital,” he said. “It’s about having the resources to build infrastructure that helps our customers move faster, simplify complexity and grow globally.”
With digital payments continuing to expand worldwide, investors believe companies capable of modernising the underlying infrastructure will play an increasingly central role in the global financial system.
