Summary: Bantu is a British financial social app that focuses on social interactions for young adults to handle expenses more easily at outings and group planning. The challenge was to redesign the information architecture based on the product vision in a way that is still familiar to financial app users. We used generative AI for branding and deviated from the all-too-common minimalist UI and brand design direction to appeal to our target audience.

Introduction

Bantu is a British financial app focusing on social interactions for young adults who want to handle expenses more easily at outings and group planning.

The challenge was to design a minimum viable product (MVP) that questioned the standard fintech app information architecture which focuses primarily on personal finance management features. The business need was to put social interactions, group chats, and being connected at the center of the experience. The product also needed to stand apart visually in a crowded competitor space.

We looked at user surveys, competitor analysis, and user tests, selected essential product features, and started ideating through user flows and wireframes to get the best from financial and messaging apps. Based on our competitor analysis and the brand’s core idea, we designed an app identity that makes it memorable and unique compared to direct and indirect competitors.

I managed the project, evaluated the research findings, worked on the user flows, the wireframes, the identity design, the final high-fidelity prototype, and the developer handoff.

The design process

Discovery and empathy

First, we collected and processed existing research data about our target audience and the digital banking app.
