Digital wallet integration for Graitor

Project type Freelance
Industry Digital services
Collaborators None

Project Overview
Graitor was a Danish startup focused on encouraging sustainable behavior through a digital rewards platform. While Denmark has a well-established bottle deposit system, many recyclable items still end up in inappropriate waste streams because users lack incentives, guidance, or simple reward mechanisms for responsible disposal.
The goal of this project was to evolve the existing Graitor 1.0 platform into a more scalable and engaging product experience for Graitor 2.0. My role focused on designing and validating a digital wallet feature that would simplify how users collect, manage, and redeem rewards for green actions. Although Graitor later closed due to political and market-related factors, the project successfully demonstrated how a digital wallet could strengthen engagement within sustainability-focused platforms.

My role
End-to-end product design from concept exploration to interactive prototype and usability testing.
