Finsei, a London-based payments firm, has partnered with Thredd, an AI-first issuer processing platform, to power the processing infrastructure behind its new Mastercard debit card proposition.
Under the agreement, Thredd will manage payment processing and automate Finsei’s back-office operations. Its technology will also provide tokenisation, push provisioning, 3D Secure authentication and transaction fraud monitoring, helping Finsei deliver a secure and seamless card experience for business customers.
The partnership targets a common challenge for companies operating internationally: managing separate providers for accounts, payments, foreign exchange, cards and expense management. Finsei aims to bring these services together through a single platform, supported by Thredd’s payment infrastructure.
Customers will initially have access to physical and virtual debit cards, with Apple Pay and Google Pay support planned for a later stage.
Finsei provides businesses with multi-currency accounts, Visa and Mastercard cards, SEPA and SWIFT transfers, and recently added acquiring services. The company is authorised by the Financial Conduct Authority and holds ISO 27001 certification. It also states that client money is held with UK and EU banks covered by FSCS protection.
The agreement adds to Thredd’s presence across the UK and European FinTech and payments markets. The company serves more than 100 FinTech firms, digital banks and embedded finance providers in over 50 countries through a single API. Its platform supports debit and credit cards, digital wallets and ledger functionality, processing billions of transactions annually.
Thredd CEO Jim McCarthy said, “Businesses increasingly expect their financial tools to work together rather than operate as a collection of disconnected services. Finsei is building around that expectation, bringing payments, currency management and business spending into a more unified experience. Thredd’s role is to provide the flexible, resilient infrastructure behind the card proposition so Finsei can focus on delivering the simplicity, control, and experience its customers expect.”
Finsei CEO Artjoms Dozorcevs added, “Our clients run businesses across borders, and they don’t want one provider for accounts, another for FX and a third for cards. Building our debit card proposition on Thredd’s infrastructure means a payment received in one currency can be spent in another from the same account, with the security controls our clients expect. Thredd gives us room to expand what our cards can do as our clients’ needs grow.”
