Silverflow has closed a USD 40 million Series B as it nears one billion transactions annually, the company said in a March 2026 post. Picus Capital led the investment, according to the cloud-native card-processing firm's announcement dated around 5 March 2026.
Silverflow sells processor infrastructure for acquirers connecting to Visa and Mastercard rails in the cloud. The one-billion-transaction run-rate figure is a company-stated scale signal rather than a scheme-audited public metric.
Proceeds are framed as growth capital for the next phase of acquirer adoption. Exact valuation, prior-round stack and other participant amounts were not fully itemised in the short blog summary.
Acquirers evaluating Silverflow should treat volume and latency claims as company-stated and validate scheme certifications, settlement controls and regional processing coverage before migration.
