Case Study: rebuy increases device grading conversions with Amplitude

How Creating a Customer-Centric Culture Led to Increased Conversions

rebuy, a Berlin-based retailer focused on the circular economy, needed a better way to understand customer behavior and reduce friction in its mobile app and website. Users interested in selling used electronics often had to navigate several screens just to get a device value estimate, limiting conversions and creating missed opportunities for rebuy.

Using Amplitude Analytics and Experiment, rebuy moved from Google Analytics to a more flexible, customer-centric data platform. With Amplitude, the team added a homepage tile that sent users directly to the device questionnaire, boosting Samsung phone grading by 30% and phones by 11%, while also increasing conversions from users who weren’t initially planning to sell. Amplitude also helped rebuy streamline experimentation, improve funnel analysis, and build a stronger data culture across teams.
