The Challenge
A European wealth management firm serving high-net-worth individuals needed to move beyond static investment reporting into an active digital financial platform. Their existing infrastructure had no payment layer, no real-time currency capability, and no digital wallet offering. The requirement was to build a fully regulated, multi-currency platform — from zero — within a tight delivery window and under full GDPR obligations.
What Was Built
A Retail Digital Wallet and Corporate Digital Wallet ecosystem supporting 27+ currencies with real-time FX conversion within the app, and options for physical cards, virtual cards, or both — all Mastercard-issued, fully branded. The platform included peer-to-peer transfers, bulk salary payments, and SSO-enabled access management. Built on a microservices architecture with tokenized card infrastructure and SOC-compliant system design — drawing on our AI integration practice for live enterprise platforms. Independent scaling of wallet, card, and FX modules was built in from the start. Integrated third-party providers covered card program management, currency liquidity, and AML screening. A reusable architecture enabled the same platform to be redeployed across multiple client engagements without a full rebuild — the same approach we offer as a productised white label digital wallet development service, delivered within our broader fintech software development practice.
Intelligent Support Triage
The platform's customer support layer was enhanced with an AI-driven triage system. Incoming support tickets are automatically reviewed, categorised by type, and indexed. For high-frequency issues with established resolution paths — such as transaction queries, card limit questions, or FX discrepancies — the system delivers a prescribed solution roadmap without human intervention. Tickets involving financial exceptions or irregular activity are escalated directly to the support team, ensuring human oversight where it matters most.
