The challenge

A fintech founder had regulatory approval and a banking partner — but no product. They needed a consumer app that felt as polished as the incumbents, shipped fast enough to hit an investor milestone, and trustworthy enough to hold people's money.

The bar was high: great UX, bank-grade security, and a clear reason to switch.

Our approach

We led with design. Two weeks of UX work produced a clickable prototype we tested with real users before writing a line of production code — killing bad ideas while they were cheap.

The differentiator we landed on: AI spending insights that feel like a friend who's good with money, not a scolding spreadsheet. Then we built it cross-platform in Flutter to ship iOS and Android from one codebase.

  • Prototype-first UX, validated with real users
  • Flutter for one codebase, two native-quality apps
  • Biometric auth, encrypted storage, PCI-aware architecture
  • AI categorisation + forecasting for budgets and nudges

What we built

Instant transfers, smart budgeting, savings goals and AI insights — wrapped in an interface that loads fast and feels calm. We shipped to both stores in 16 weeks, then supported the launch with analytics and rapid iteration.

The results

0installs in 8 months
0average across both stores
0weekly active retention

The app cleared its investor milestone on time and became the company's primary growth channel. The AI insights feature is the single most-cited reason users give for staying.

In their words

WeGrapps shipped a product that looks like it came from a 50-person company. Our users can't believe we're a startup.
