Creating an MVP — Carrefour Liberté App
The Carrefour Liberté mobile app MVP enables Carrefour Location to offer customers a continuous 24/7 vehicle rental service that is seamless and 100% digital.
MVP challenges
Carrefour Location had already made its first digital pivot with an e-commerce site (built with STEAMULO in 2016) centred on the user. In 2020, it wanted to get even closer to customers and break free from physical stores to deliver its promise: « Affordable and close to you ».
Revolutionising self-service rental
- Offer a 100% digital, autonomous customer journey via a dedicated mobile app
- Rebuild the IS as a tool capable of interpreting telematics data (Big Data, partner APIs)
- Support stores and customers through the digital transformation and enable preventive maintenance via telematics
An app integrating multiple functional building blocks
The app relies on a set of partner solutions (French startups) to cover the entire self-service rental journey 24/7:
- Virtual key & telematics: Mov'in Blue SDK to lock/unlock the vehicle via smartphone, with real-time telematics reporting.
- KYC: Identity document and driving licence verification at registration via the AriadNext solution.
- Electronic signature: Paperless signing of the rental agreement directly within the app.
- Digital condition report: Certified check-in and check-out reports (Weproov), admissible as evidence in disputes.
- Legally binding storage: GDPR-compliant storage of IDs, contracts and condition reports via DOCAPOST's OKORO solution.
- Mobile payment: Deposits, security deposits and payments via Adyen SDK, with certain card types blocked.
An iterative Design Thinking sprint methodology
To help CARREFOUR create a 100% digital and autonomous customer journey, we operated through successive iterative Design Thinking sprints. This methodology delivers concrete results quickly by setting achievable goals per sprint.
STEAMULO positioned itself as a technical solution integrator, helping CARREFOUR test and validate partner software components (French startups) to integrate via SDK into iOS and Android apps, or via API into the back office.

Conclusion
After six months of operation, the service was discontinued due to several factors: faster-than-expected battery drain caused by the onboard unit's power consumption, unanticipated self-service usage patterns, and a return on investment below expectations.
Despite this, the experience proved highly instructive and served as a catalyst for innovation within Carrefour, which is now exploring improvements and adaptations for the future.
