The Challenge
The fintech market in Brazil is extremely competitive, with established players like Nubank, Inter and C6 Bank dominating the scene. Shepper Bank needed to differentiate itself not only in features, but mainly in user experience.
How to simplify complex banking operations without losing functionality?
How to create trust in a new brand in the financial market?
How to serve different user profiles with a single experience?
The Solution
We developed a user-centered approach that prioritizes simplicity without sacrificing functionality. The "progressive disclosure" strategy reveals advanced features as the user needs them.
