### ClearScore – Native Mobile Expansion for a Leading FinTech

ClearScore, one of the UK’s leading fintech companies, engaged NEXTAP to design and develop their first native mobile application. We delivered the initial iOS app and contributed to Android development, UI and UX design, and web components. Early in the partnership, part of our team relocated to London to work directly from ClearScore’s offices and support the build-out of their in-house engineering team. Our developers contributed beyond feature delivery, taking leading roles in architectural decisions, modularization, backend-for-frontend transitions, redesign initiatives, localization releases, and navigation overhaul. Over time, our role evolved into providing specialist expertise as ClearScore scaled internationally.

### Bippit – End-to-End FinTech Product Development

Bippit approached NEXTAP at the beginning of their journey to help bring their financial product to market. We supported product shaping, UX and UI design, and delivered the first native iOS application. The app included core features such as message chat, video chat, and banking integrations within a fully native platform. As the product expanded, we built the web application, backend systems, admin tools, and initiated Android development . Our team integrated directly with Bippit’s internal operations and scaled responsibilities across the full ecosystem. After six years of collaboration, development was successfully handed over, with NEXTAP continuing in a consulting capacity.

The collaboration also included long-term support and ongoing system improvements. The client emphasized NEXTAP’s strong sense of ownership and deep understanding of their business processes.

Bippit engaged NEXTAP at an early stage to help design and build their financial wellbeing platform. The scope included UX and UI design, development of the native iOS application, web platform, backend systems, and later the Android app. NEXTAP supported the product from initial concept through launch and subsequent growth phases. As the platform evolved from a B2C to a B2B model, the team adapted to shifting requirements and expanded their responsibilities to include backend development, admin tools, and broader system architecture. The client noted strong collaboration, effective project management, and consistent communication throughout the engagement. The apps were successfully launched and received positive feedback from end users. The partnership extended over several years, ultimately transitioning into a consulting relationship after the core development phase was completed.
