"I did many public speaking and communication courses, that's the first time I can actually take away something."

“I was fearing having to present before that. Now I look forward to opportunities to talk.”

Training grounded in real business situations

High-stakes presentations rarely happen on a conference stage. They happen in boardrooms, client meetings, investor pitches, or trade shows. Our approach focuses on actual professional settings. It makes you stand out on stage, but differentiates you even more at a board meeting.

By someone who's been in the room like you.

Damien Gauthier is bridging two worlds: mathematician PhD from EPFL turned IT consultant and UX designer on one hand; professional actor, director, TEDxLausanne curator and speaker coach on the other.

He created the Impactful Speaking Method to fill the gap between public speaking and the business world, blending secrets from consulting, acting techniques, cognitive science, storytelling frameworks, and 12 years of corporate experience.

His focus is on public speaking as a strategic communication device, not as performance: structuring ideas to build a clear message, creating presence to build credibility, and delivering presentations that feel fully authentic.
