Presentation & Communication Training for Experts and Teams

You have the expertise. We provide you with a method to turn that expertise into clear messages, compelling presentations, and concrete decisions, from the initial idea all the way through your interactions with your audience.

As responsibilities grow, so does the importance of good communication. Experts roles evolve from solving problems to explain complex ideas, engage clients and stakeholders, and influence decisions.

We offer practical workshops, talent development programs, and individual coaching, to help experts, leaders and their teams turn their expertise into business impact.

You have the knowledge, yet sometimes it does not come across.

Most experts experience the Curse of Knowledge: the gap between what's clear in our mind and what lands in the room. That gap is closable, if it has a structure.

"You prepared. It still came out wrong."

You prepared well, but when the moment arrived, something took the best of you.

"Your audience gets lost on complex slides."

You build a deck covering everything. The audience is either lost or stuck on details.

"Rehearsal feels like going in circles."

More dry runs produced the same result. Repetition without method isn't the answer.

"You start dreading speaking altogether."

You know which presentations are critical, yet you find reasons to defer them.

Not another soft-skills course:
actionable frameworks & usable techniques.

Communication isn't just a talent. It's a skill you can develop.

Our approach combines the structured thinking of consulting with practical techniques from theater and public speaking around three pillars.

Clarity

Structure your ideas so people understand your message.

Purposefully build arguments that convince your audience.

Presence

Use your voice, body, and delivery to communicate with confidence and credibility.

Be charismatic and engaging without putting on a show.

Voice & Pace Stage presence Deliberate gestures Eye contact

Connection

Make your message relevant, engaging, and convincing for your audience.

Your audience's trust is not given, learn to command it.

Connection

Pathos — the resonance with your audience

Your audience's trust is not given. It is built through specificity, relevance, and a demonstration that you understand their world.

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

Jean-Raphael Guillaumin · Senior Project Manager · SQLI

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

Built for when it truly matters: boards, clients, committees...

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.

"You won't sound like a TED speaker. You'll sound like the most prepared version of yourself."

PhD in Mathematics Innovation Consultant Theater & Improv TEDxLausanne

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.

BOBST × Drupa 2024 — 64 Experts. 3 Days. 4.8/5.

Drupa is the most important commercial event in the print industry, held once every four years in Dusseldorf. BOBST needed 64 technical experts to present with confidence, clarity, and commercial impact on the booth floor. We built a hybrid program mixing remote training and coaching, live bootcamp in Switzerland and Italy and presence in Dusseldorf for three days before drupa's launch. The result: measurably prepared, measurably better.
