Silverflow, a cloud-native card payment processing platform, has partnered with Griner, a Cyprus-based payments processor, to support the latter’s expansion across European markets. The companies said the partnership follows an initial launch in Cyprus, where transaction volumes have increased month on month as more merchants have joined the platform.
The partnership combines Silverflow’s card processing infrastructure with Griner’s acquiring and payment services for payment service providers (PSPs), marketplaces and e-commerce businesses. The companies said the setup is designed to help Griner scale its acquiring operations without having to build a new processing infrastructure internally.
Griner Finance Ltd is registered in Cyprus and operates under the supervision of the Central Bank of Cyprus. According to the company, it is a principal member of Visa and Mastercard and provides acquiring services for merchants across the European Union. Its offering includes e-commerce and marketplace payments, hosted payment pages and cross-border payment processing.
For marketplaces, Griner provides services including seller onboarding, split payments and chargeback and risk management. The company also offers an API-based integration and supports multiple payment methods and currencies.
The companies said the initial Cyprus rollout has resulted in faster merchant onboarding compared with Griner’s previous infrastructure. They also reported steady growth in transaction volumes since launch, although they did not disclose specific transaction figures.
Sveta Bulshtein Krasnov, CCO at Griner Finance Ltd, said: “Griner moves fast. We needed a technology partner that could keep up. Silverflow gave us that from day one. When we launched, we went live quickly. Our merchants got what we promised them: a flexible, efficient and streamlined payment experience from the first transaction. Our vision requires an infrastructure that works now and scales with us. Silverflow was a natural partner to help us deliver that.”
The companies now plan to extend the partnership to additional European markets, with projects already underway, according to the announcement.
Nigel Thacker, Chief Commercial Officer at Silverflow, said: “What’s been great to watch is how quickly Griner has been able to translate agility into real results in Cyprus. They’re ambitious, they move fast, and they’re not willing to compromise on the personal relationships they’ve built with their merchants just because they’re scaling up. That’s the whole point of a modern acquiring platform: it should get out of the way and let global payment processors like Griner focus on what makes them different.”
The deal also reflects a move among payment companies toward cloud-based acquiring infrastructure. Silverflow’s platform connects directly to card networks through APIs and provides access to transaction data, while its platform includes functions such as 3D Secure, network tokenisation, direct-to-card payouts and dispute management.
Compared with traditional acquiring infrastructure, cloud-native platforms can allow payment companies to deploy and update processing capabilities without maintaining the same type of legacy, on-premises systems. Silverflow has previously used this model in partnerships with financial institutions and payment companies, including Deutsche Bank, which launched a cloud-native acquiring platform with the company across Europe in 2025.
For Griner, the partnership provides the processing infrastructure for its next stage of European expansion while allowing the company to continue focusing on acquiring, merchant relationships and payment services.
