💼 Client
An Estonian startup founded by father and son, Marti and Joosep, developed RallyPin to transform the rally spectating experience. Inspired by Joosep’s motorsport journey and feedback from spectators, the app simplifies event navigation with interactive maps, schedules, and unique routing that avoids rally stages. Initially created to solve a personal challenge, RallyPin is now evolving with exciting new features to attract more fans and enhance rally events. Building on their success, the team is now working on an exciting new app for drivers, set to launch soon.
🦄 Product
RallyPin began as a tool to enhance rally spectating, solving the common challenge of finding the best spots and schedules during events. The app consolidates all essential rally information into one seamless platform, allowing users to explore interactive rally maps, discover viewing areas with pictures, and enjoy one-click navigation powered by a unique algorithm that avoids rally stages.
Spectators can track live results, access timetables and entrants, and even see the starting times of the first car and their favorite driver during navigation. RallyPin not only elevates the rally experience for fans but also helps organizers engage more spectators by making events more accessible and enjoyable.
The app operates on a subscription-based model, offering flexible plans such as per rally, 6-month, and 12-month subscriptions, ensuring users can choose what suits them best. The founders actively collaborate with organizations like the Estonian Autosport Union and other key stakeholders to grow the product's reach and impact, establishing RallyPin as an essential tool for the motorsport community.

Solutions
⚙️ Process
We started with setting up a dedicated team which includes engineers, designer and a project manager. Following that, our designer finalized the UX/UI design, and the engineers began developing the frontend and backend parts. After the MVP release, the team transitioned to ongoing app maintenance adding new features.
We held regular weekly meetings with the client to align on goals and to address any issues. Project management included task tracking, milestone setting, and ongoing client communication.
This approach helped us finish the MVP in 4 months, delivering a successful product.
