Stéphane Martin
PresidentA committed strategist with hands-on experience, Stéphane built his career at the intersection of operational performance and human development. After beginning in sales and negotiation at Henkel, he went on to lead several HR consulting and services businesses (Develop’Invest, La Centrale de Formation, and as a member of the Executive Committee at Alixio), supporting large enterprises through major transformations.
Convinced that people are the key to any sustainable success, Stéphane places managerial agility and emotional intelligence at the core of his convictions. He believes deeply that no situation is set in stone: any team can reach excellence, provided it’s guided by strong leadership.
What drives him? Creating environments that enable growth, engagement, and accountability. Emotional intelligence marked a turning point in his leadership: it became an essential lever to navigate turbulence. And turbulence is now a daily reality. Today, with Power 21, Stéphane works to ensure every leader can face a complex world by combining human strength with tangible results.
