Within a rapidly changing sector, Retreeb presents a new means of payment, simple, practical, economical, which allows it to comply with the universal values such as ethics, sharing and solidarity. It targets all persons who are part of a solidarity and sustainable approach. In consideration of their adoption of the service, Retreeb commits to its users to pay 33% of the transaction fees collected by Retreeb to the funding of social and environmental projects. With this business model, the technical infrastructure, the redistribution of transaction fees, and the monitoring of projects, they opt for an unprecedented level of transparency in a particularly opaque sector. Concerned about environmental issues, their technological choices are determined by a desire to reduce our carbon footprint to its strict minimum. Finally, they take a new approach to payment by placing corporate social and environmental responsibility (CSR) at the heart of their ambitions.
