About Léo

Strategy, marketing, and growth consultant, I support startups, SMEs, and project leaders in developing and structuring their ideas. My role: to transform a vision into a concrete, profitable, and scalable project.
I intervene in both the upstream phase (strategic framing, positioning, value proposition, go-to-market) and the execution phase (digital marketing, customer acquisition, sales structuring, project launch). My approach is very operational, results-oriented, and adapted to the real constraints of teams.
As an entrepreneur myself, I understand business challenges, rapid trade-offs, and the need to move forward effectively. I bring a global vision, combining strategy, marketing, and business development, with clear and actionable deliverables.
Types of assignments: growth strategy, offer structuring, project launch, marketing & acquisition, business support.
