Revolutionizing Global Banking: How Zenus Bank Built an Infrastructure Bank with Tuum and Purpleplum [case study]

Unlocking the Future of Embedded Banking

Zenus Bank set out to do what many thought was impossible—enable global businesses and individuals to access U.S. banking services seamlessly. To achieve this, they needed a modern core banking solution that was scalable, compliant, and capable of delivering a seamless embedded banking experience.

With Tuum’s cloud-native core banking platform and Purpleplum’s user-centric digital wallet, Zenus Bank transformed from a retail-focused neobank into a leading Infrastructure Bank, offering embedded accounts, cross-border card issuance, and multiple payment rails for financial institutions worldwide.

The Challenge: Scaling from Retail to Infrastructure Banking

Zenus Bank initially launched as a mobile-first, retail-focused digital bank, proving the viability of its global banking model. However, to scale and serve financial institutions, the bank needed to:

  • Scale quickly and efficiently to meet growing international demand.
  • Ensure global regulatory compliance across multiple jurisdictions.
  • Deliver a seamless, customizable banking experience to financial institutions and fintechs.

The Solution: A Unified, Modular Approach

Zenus Bank selected Tuum as its core banking provider and Purpleplum for digital front-end innovation. Together, they delivered:

  • API-first, cloud-native architecture to enable real-time data synchronization and seamless integrations.
  • Modular core banking capabilities supporting embedded finance, virtual accounts, and international payments.
  • Customizable digital front-end for financial institutions, allowing for unique user journeys and personalized banking experiences.

Results: A Game-Changer for Embedded Finance

  • 12-month transformation – Zenus Bank launched its new platform in record time with a phased migration strategy.
  • Seamless cross-border banking – Supporting multi-currency accounts, international payments, and embedded banking.
  • Enhanced financial services – Zenus Bank now provides digital wallets, corporate expense tools, and regulatory compliance solutions to global institutions.

“Zenus Bank is changing the game by giving fintechs and businesses the infrastructure they need to embed financial services and go global.”
