NovaBank is a digital banking platform with eight million active customers across six countries, offering everyday banking, savings, and credit products entirely through mobile. The fraud detection engine behind the platform was technically sophisticated and genuinely effective at catching fraudulent transactions, but the customer experience wrapped around it had never been designed with the same care.

The research phase began with a detailed audit of every touchpoint in the existing fraud alert journey. When a suspicious transaction was flagged, customers received a generic push notification that said their card had been temporarily suspended, with no information about which transaction had triggered it, no indication of what to do next, and a deep link that dropped them on a home screen with no clear path forward. Customers who called support were placed in a queue averaging eleven minutes, and those who tried to resolve it through the app encountered a three-screen verification flow that asked them to re-enter their full card number, answer a security question, and then wait up to 15 minutes for manual review before their card was reactivated.

After reviewing session recordings and funnel data, it became clear that the platform was asking users to pay before they truly experienced meaningful value. The pricing page was feature-heavy and overwhelming, listing technical differences instead of tangible outcomes. Instead of pushing users toward a static pricing page, I proposed a shift in strategy—moving from feature-based selling to value-triggered upgrading. The idea was to let users reach moments of high intent inside the product and introduce upgrades contextually, exactly when they were trying to access a premium feature.

Average resolution time for a false positive fell from over 15 minutes to 38 seconds. The NPS gap between customers who had experienced a false positive and the platform average closed from 41 points to 9 points. Card reactivation through self-service, without any agent involvement, went from 23% to 87%. The insight that ran through the entire project was that fraud protection and customer trust are not in tension with each other, they depend on each other. When a system treats every customer like a potential threat and gives them no agency in their own resolution, it erodes exactly the kind of trust that a banking product needs to survive long-term. The redesign did not make the bank's fraud system less rigorous. It made the customer feel like a partner in it rather than a suspect caught in it.
