How Carrefour Links Transformed Data Quality and Efficiency Across 8 Countries with Sifflet

Carrefour is a French multinational retail and wholesaling corporation that drives upwards of 90 billion euros in annual revenue per year. Carrefour Links is the group entity that develops and commercializes data products for industrial players such as Mondelez, Proctor & Gamble, and Unilever, providing insights to evaluate the entire journey of their marketing campaigns from advertisement to in-store transaction and ranking against competitors in specific categories. 

Carrefour Links creates these products thanks to a wealth of data generated by 80 million customers and 12,500 points of sale spread across 40 countries.

Balancing Data Quality and Innovation: Carrefour Links' Observability Challenge

Carrefour Links collects and modelizes data from over 40 countries where the group operates.  Ensuring a high-level of data quality is essential to commercializing its data products for multinational industrials. The team at Carrefour Links had originally tried to develop their own in-house observability solution, but quickly ran into trouble balancing engineering capacity dedicated to developing data quality checks and creating new product features. They needed an integrated solution that allowed the team to define monitoring rules, trace data lineage, and diagnose issues, to free up engineering capacity to work on strategic projects.
