Product Development Team
LiteBit needed a technology partner who could move fast without breaking things in one of the most demanding industries in the world. BrightMarbles embedded our engineers into their team and co-owned the product from day one — from mobile app architecture to regulatory adaptation.
Our contribution
Our Contribution
We developed LiteBit's cross-platform mobile app from the ground up in Flutter, replacing a struggling dual-track React Native approach. Our team delivered the full Android and iOS app within six months, exceeding the original version in functionality and performance.
Challenge
The Challenge
The LiteBit team was simultaneously maintaining a React Native iOS app while building an Android version from scratch — a drain on resources that was slowing their ability to compete. They needed a faster, more secure, and unified solution that could scale to hundreds of thousands of users.
