The Challenge

Scaling the Data & Analytics function proved difficult as hiring Feature Store Engineers became increasingly expensive. The organization faced a critical decision: continue hiring expensive headcount for routine tasks or find a way to automate the feature-store workflow without sacrificing quality.

"The senior Feature Store Engineer spent 80% of their time on feature pipelines, serving infrastructure, feature registry. A Mistral Large agent now handles this workload autonomously, 24/7."
