Our clients testimonials

The growth marketing agency LES CAUSANTES has been a partner of the Auchan group for several years: a team of professionals bringing together real business experts, always responsive and force of proposal! The team supported Auchan in the design and implementation of the new Social Media Retail strategy for our 14 countries, based on our 2 main social networks Facebook and Instagram. In less than a year, we have been able to rebuild the social architecture, define a new editorial line, deploy and significantly improve engagement KPIs and thus prove that we can generate incremental ecommerce and drive to store revenue with our social presence and in particular our store pages. All this thanks to strategic advice, but also to the daily operational work of the agency’s teams?
