About Maxime

Retail Media (Unlimitail — JV Carrefour x Publicis, collaboration with international agencies including OMD) · E-commerce & Shopify (The OZ) · Transport & Mobility (CorsicaLinea)

🎯 Areas of Expertise

QBR, business reviews, strategic recommendations
Management of renewals and identification of upsell opportunities

🧠 Approach & Know-how

Accustomed to managing a portfolio of accounts in parallel (up to 50 simultaneous accounts), I work in close collaboration with the Sales, Product, and Operations teams. Autonomous and proactive, I bring an analytical, results-oriented approach based on identifying friction points and making data-driven decisions. I also have a strong appetite for structuring internal processes, having managed two CS tooling projects (Wrike, Monday.com) in parallel with my client responsibilities.
