How to set up relevant, personalized marketing campaigns that meet customer needs? 

Mobilize Financial Services (formerly RCI Banque) is a subsidiary of the Renault group, in charge of financing solutions for vehicle purchases. In 2019, the company had a turnover of 2.1 billion euros for 3700 employees. 

In 2016, RCI Banque’s international subsidiaries had multiple customer and contract management systems that were not consolidated. The data was repeated several times and was not kept up to date. Then, RCI Banque decided to launch a big data plan, which aims to improve the knowledge of each of its customers in order to be able to conduct relevant personalized marketing activities according to the needs of its customers through the right channels.
