About Isabelle

Do you want to structure your marketing, accelerate your growth, or improve your customer experience?

I support B2B, industrial, tech, eCommerce, and service companies in building a clear, high-performing, and directly actionable marketing strategy: positioning, lead generation, go-to-market, marketing automation, digital optimization, customer experience, corporate communications, and marketing transformation.

With 17 years of experience at Carrier, Kidde Global Solutions, Kantar, Edelman, Ipsos, and Dassault Aviation, I have managed international brand, digital, eCommerce, CX, and communication projects in complex, multi-country, and post-acquisition environments.

I can act as a senior consultant, fractional CMO, or outsourced marketing director to deliver concrete deliverables: marketing audit, growth plan, 90-day roadmap, content strategy, messaging, funnel optimization, CX/NPS program, commercial activation plan, team structuring, and change management.

My added value: combining strategic vision, business understanding, and concrete execution. I help you move from scattered marketing to structured, measurable marketing aligned with your growth objectives.
