Reviewed on 3/25/2026

Karim assisted us with the complete structuring of ENNU, with both a strategic and highly operational approach. He didn't just produce a strategy: he clarified the positioning, secured the regulatory framework, and most importantly, made the brand truly sellable and manageable. The deliverables are immediately actionable (conversion, sales scripts, KPI monitoring) and allow for quick decisions based on concrete data. His involvement goes beyond the standard scope of a mission: Karim challenges, makes decisions, and brings a real results-oriented business vision. I highly recommend him for any brand looking to structure its growth and measurably improve its commercial performance.
