We asked Rebold AU founder, Gautier Favier, about building an app that helps you sell your old smartphone, tablet, or smartwatch at the best price available, while also reducing e-waste footprint. Rebold.com.au works with refurbishing partners across Australia to responsibly recycle devices, providing a sustainable alternative to traditional consumption. Users can choose to sell over 400 devices online and get the best offer based on device condition, with a prepaid eco-package sent for free. Gautier chose Bubble due to its powerful no-code platform, which provides an end-to-end experience with strong backend capabilities. Rebold's goal is to change consumer perceptions of electronics interaction, moving towards a circular economy where devices are sold or recycled after use. The app has seen success in integrating partners and receiving positive community feedback, with plans to expand into new areas such as buying refurbished electronic devices.
