Executive leadership for Enterprise transformation

From Strategy to Impact

Portrait of Philippe Guérineau
About

Philippe Guérineau, Founder & CEO

Twenty-five years of executive mandates in chemicals, polymers and process industries across Europe. Not as an outside consultant, but as the executive mandated by shareholders and boards — with full P&L responsibility and the authority to act.

I step in where the complexity is real: restructuring, turnaround, constrained growth, post-acquisition integration, strategic transformation. In each of these contexts I build cohesive, results-driven teams able to execute quickly and to hold the line over time.

What sets me apart: uncompromising operational discipline, paired with sharp strategic reading and a proven ability to create lasting value — even on difficult ground. I run two to three mandates concurrently, selected for their complexity and stake.
