An Integrated B2C Mobile App for a Renowned Retailer

Cloud Interactive provides a comprehensive and integrated design, utilizing new retail marketing, sales, and customer management tools to assist Carrefour in improving return on investment and increasing sales opportunities. Carrefour also collaborates with Cloud Interactive to explore various innovative app functionalities, such as app red packets, coupons, and interactive queue games, aiming to offer customers a more diverse and integrated digital service. Our design and R&D team targets the business needs of our clients, using high-quality training models to create highly customized solutions, successfully facilitating Carrefour's digital transformation. We look forward to maintaining a long-term partnership with Carrefour in the future. Recently, we integrated Carrefour's EC APP and Marketing APP for a current analysis and designed the ONE Carrefour APP, which includes a more complete and seamless user consumer experience, streamlining the shopping process, and increasing customer brand loyalty and dependence. Several new features are being added, including a badge achievement system, coffee delivery service, share codes, and parking payment services. We have consolidated various existing Carrefour apps and systems into the ONE Carrefour APP, allowing users to access the functionalities of two or more previous apps using just one app.

The mobile revolution has changed the way retailers interact with customers and has impacted customers’ buying habits. Business innovation cycles are shrinking faster than ever before to keep pace, mirroring customer expectations and fast-changing preferences. Carrefour Taiwan, as one of the largest retailers in the world, has brought forward many bold ideas to reinvent the shopping experience for customers. While turning ideas into reality is never easy, the team at Cloud Interactive embraces the challenge. We use innovative methods to design, develop, and improve products and processes in record time.


Cloud Interactive started from the ground up with usability research. We then provided several eye-catching UI designs and integrated the app with Carrefour’s existing back-end infrastructure.

Our team worked with many of Carrefour’s vendors and used an API to integrate the functionality of previously existing apps into a single platform. With our full-stack engineering capability and in-house design team, we were able to bring Carrefour’s innovative ideas to life by creating its industry-leading app.
