Case
Billo
Designing a new kind of app from scratch – to handle something as physical as postal mail in a completely digital way. From early concepts used for investor pitches, to a testable MVP, and finally a polished v1 for launch, I worked end-to-end with UX and UI in a fast-paced, tech-driven startup environment.
1.
Billo set out to solve a unique problem: how to manage all your physical mail digitally, securely, and effortlessly. No competitor had solved this before. The challenge was not only technical – it was also about user trust. How do you convince users to hand over something as sensitive as their paper bills and legal documents?
2.
As part of NoA Ignite’s cross-functional team, I was the lead designer on the project. I worked closely with developers, system architects, and stakeholders to translate a complex technical service into a simple and intuitive user experience. My role covered both UX and UI for the MVP and later the native v1 app.
3.
MVP Phase – Fast & Focused:
v1 App – Native, Brand-Driven, and User-Friendly:
4.
5.
We launched a clean, minimal app that users described as “surprisingly simple.” The goal was for the app to feel empty – in a good way. A place where nothing required attention because Billo had already taken care of it. The app achieved a seamless onboarding experience and built the foundation for Billo’s in-house development team to take over.
6.
This project taught me the value of radical simplicity. I learned how to distill complex backend logic into user flows that felt effortless. I also gained deeper experience working closely with system architects and developers, making product decisions early in the life of a product. Following the project from blank page to launch gave me a strong sense of how structure, hierarchy, and navigation decisions shape the entire experience.
