Jerome Viro - Speaker on decision making
The researcher turned mentalist. Your teams experience what truly influences their decisions, and they don't forget it.
What we cannot explain, we never forget.
Your teams have already seen dozens of conferences. They have retained little. What remains is what we felt.
This is the bet of my interventions. On stage, I do what everyone believes is impossible: guessing a thought, predicting a choice, influencing a decision in front of everyone. The audience participates, reacts, searches, doubts. The surprise, then the emotion: attention is total. It is at this moment that I talk about you. About your decisions, your blind spots, what influences your teams without them seeing it. Mentalism is never the subject. It makes visible what no slide can show, and it engraves it in memory.
FROM THE LABORATORY TO THE EXECUTIVE COMMITTEE I spent twenty years in the technology industry. Researcher first, PhD in science, author of over 100 patents. Then R&D director, CTO, and general manager: hundreds of people to move forward together, international teams, international standards to negotiate, heavy arbitration under pressure. Throughout my career, I have led international research projects, published, and given conferences in France and internationally. I do not speak about your issues from the outside: I have lived them. I have drawn a conviction from it: a leader's blind spot is never in their market, it is in their head.
At the same time, I have been practicing mentalism for over 20 years. Today, I have combined the two.
WHAT I OFFER Conferences on decision-making, AI, influence, creativity, and transformation. A show, The Invisible Threads. Team building where your teams become mentalists themselves. Always built with you, around your message.
WHAT REMAINS A moment that is talked about for a long time. Concrete markers, usable from the next day. And a useful doubt that never leaves you.

What did Jerome Viro do before becoming a speaker?
I spent twenty years in the technology industry: researcher, PhD, author of over 100 patents, then R&D director, CTO, and general manager. At the same time, I have been practicing mentalism for over 20 years. Today, I combine these two paths to show the audience the mechanisms that influence our decisions.
Why book Jerome Viro rather than another speaker?
Because I understand the decisions, trade-offs, and transformations of the company from having experienced them. And because I don't just talk about it: through mentalism, I provide the audience with an experience that gives a different weight to the ideas I share.
What is Jerome Viro's speaking angle?
Bringing together the experience of the mentalist and that of the leader. My method can be summed up in three words: surprise, emotion, cognition. On stage, I create surprise and emotion; I then draw on research and my business experience to shed light on what the audience has just experienced. Sometimes abstract mechanisms become very concrete situations: a decision to make, an idea to defend, a team to move forward. With one question in mind: what does this change for you starting Monday morning?
How does the audience experience a talk by Jerome Viro?
The audience participates, always. Some join me on stage, and the entire room is engaged. Everyone can take part in the experience without ever being put in a difficult position. I alternate surprise, humor, and moments of reflection, with a pace that allows space for emotion. People have a good time, and that's also why they remember.
His conferences
Deciding in the Age of AI: Governing AI Without Abdicating Decision-Making
Deciding with AI Without Losing Human Discernment.
Generative AI produces fluid, structured, convincing responses. This is precisely what makes it dangerous for decision-making. Your teams are already using it: one committee validates a generated analysis without counter-expertise, another gradually delegates its arbitration to it. The question is no longer "should we adopt it?" but "who decides when AI confidently makes a mistake?".
WHAT YOUR TEAMS EXPERIENCE Through mentalism experiences, the audience directly feels the mechanisms that AI unwittingly exploits: our trust in what is fluid, our desire to hear what comforts us. Four illusions become visible: authority, coherence, alignment, control. And one conclusion becomes clear: the problem is not AI, it is the way we decide with it.
WHAT THEY TAKE AWAY The D.I.R.E. method to maintain control: Decide what remains human, Question each response against reality, Refute by demanding evidence, Frame with rules of use.
WHY ME As R&D Director, CTO, and General Manager, I have led major technological transitions. I have seen from the inside how teams adopt, resist, or divert new tools. AI reproduces the same patterns, only faster.
FORMATS Keynote of 45 to 60 minutes, for 20 to over 1000 people. Masterclass of 3 hours to one day, for 12 to 25 people, with AI risk mapping, usage charter, and checklist. In French or in English.
Transformation is a conversation: aligning a collective, getting buy-in for change
Why do 70% of transformations fail despite brilliant strategies and impeccable roadmaps? Why do teams resist, even when change is clearly necessary?
Because organizations treat transformation as a technical project, whereas it is primarily a conversation. Resistance is not bad will: it is the natural reaction of a brain that is losing its bearings. The problem is rarely the strategy. It lies in what is happening, or not being said, between people.
WHAT YOUR TEAMS EXPERIENCE Through mentalism experiences, the audience feels live what holds back a collective, even a motivated one: the bearings that are lost, the signals that are not seen, what each person keeps to themselves. Then I decode each mechanism.
WHAT THEY TAKE AWAY The invisible mechanisms of resistance, and how to defuse them. The mental load of change, which exhausts transformations halfway through. The conversations that unlock, where presentations fail. Guidelines for steering at the pace of people, not just at the pace of the calendar.
WHY ME As a CTO and general manager, I have led technological pivots under pressure, integrations after acquisitions, and teams that grew from 10 to 100 people in two years. I do not bring a theory of change, but what I have seen block, and unblock.
FORMATS Keynote of 45 to 60 minutes, from 20 to over 1000 people. Masterclass from 3 hours to one day, from 12 to 25 people. In French or in English.
The invisible influence and impact: convincing with precision, inspiring trust
Convincing is not just a matter of arguments.
In front of a committee, a client, or a team, your impact relies on mechanisms that no one sees: what captures attention, what shapes perception, what sways a choice. Ignoring them means letting others use them in your place.
WHAT YOUR TEAMS EXPERIENCE Through mentalism experiences, the audience sees live how attention is guided, how perception is oriented, how a decision is influenced, including their own. Then I decode each mechanism and transform it into a usable reference.
WHAT THEY TAKE AWAY Understanding what sways a choice for their interlocutors. Spotting the moment when they are influenced. Building a message that meets the real needs of those who listen. Building lasting trust, without manipulation.
WHY ME As a CEO and CTO, I have had to convince boards and international investors, and engage teams. I do not speak of manipulation, but of ethical influence: understanding the other to move forward with them.
FORMATS Keynote of 45 to 60 minutes, from 20 to over 1000 people. Masterclass of 3 hours to one day, from 12 to 25 people. In French or in English.
Unlocking Strategic Creativity: Your Teams Have More Ideas Than They Think
Innovating Under Pressure, Turning Constraints into Leverage.
How to maintain a culture of innovation when cycles shorten, budgets tighten, and doubt creeps in? The challenge is neither a lack of resources nor a lack of ideas. Your teams have more than they think: they hold onto what they know and discard their own ideas, believing them to be obvious.
WHAT YOUR TEAMS EXPERIENCE Through mentalism experiences, the audience discovers live how little their 'free' ideas actually are: the brain prefers to reproduce known solutions, and the expert even more so. Then they see the constraint change sides: when well chosen, it no longer blocks, it compels invention.
WHAT THEY TAKE AWAY Distinguishing the frameworks that close off, the habits, from those that compel invention, the true constraints. Concrete techniques to produce novel solutions when resources are lacking. A way to move forward in uncertainty: test small and fast rather than betting on the right idea. And a rightful place for AI, a machine for producing the probable: create with it, test with it, keep the verdict for the real.
WHY ME R&D Director and CTO, over 100 patents: I have led innovation where it was a matter of survival. I am not talking about a concept, but about what I have practiced for twenty years.
FORMATS Keynote of 45 to 60 minutes, from 20 to over 1000 people. Masterclass from 3 hours to a day, from 12 to 25 people, with a workshop on innovation under constraint. In French or in English.
The audacity of lucid decision-making: deciding in uncertainty, arbitrating under constraint
Why do brilliant leaders sometimes make disastrous decisions?
In a complex environment, rationality fades in the face of our biases: anchoring, the illusion of control, confirmation bias. These blind spots are not mere judgment errors. They are real, industrial and financial costs.
WHAT YOUR TEAMS EXPERIENCE Through mentalism experiences, I make the audience live, in real-time, the invisible mechanisms that distort our perceptions. Each person sees their own judgment skewed, without realizing it. It is this moment that makes the rest possible.
WHAT THEY TAKE AWAY Identifying where and how judgment goes awry. Regaining analytical clarity when data is lacking or contradictory. Instilling vigilance reflexes in management committees. Concrete benchmarks to use from the next meeting onward.
WHY ME As R&D Director, CTO, and General Manager, I have spent fifteen years leading organizations where every arbitration engaged the future. I know the solitude of the decision-maker in the face of complexity: arbitrating between disruption and stability, convincing demanding stakeholders, deciding without having all the data.
FORMATS Keynote of 45 to 60 minutes, from 20 to over 1000 people. Masterclass of 3 hours to one day, from 12 to 25 people, with a personalized decision-making checklist. In French or in English.
