Case study
The brief
Two founders wanted a budgeting app for people who share a flat: who paid for what, what is due, and no awkward messages.
What I did
I designed the product from first sketches to a tested prototype, then built the web app in React with the founders over eleven weeks, including the design system and the onboarding.
Result
Brindle launched with 3,000 households on the waiting list and a 61% week-four retention.
