Trained in the human sciences, experienced in the fields of studies and consulting, and committed to the fine integration of augmented intelligence, we share the same requirement of rigor and the same intellectual curiosity while applying them to different areas of expertise: quantum, quality, quality, semio, cognitive sciences, technological integration...
It allows us to approach each problem from multiple angles and to build very rich analyses.
We made the strategic choice to develop and operate our own private technical infrastructure, controlling every link in the chain. This choice guarantees us total control of our processes and the maximum degree of sovereignty over the data you entrust to us, which the “black boxes” of public platforms do not allow.
Founder & CEO
With a master's degree in social psychology, I have always attached great importance to the hybridization of qualitative and quantitative approaches, the only way in my opinion to be able to fully understand human complexity. After a career in various institutes, I created h2\ with several partners to be able to benefit from a wealth of points of view and expertise. Passionate about innovation and technology, I have specialized over time on quantitative methods, advanced data processing and the modeling of complex subjects. I devote my free time to reading, mountain biking in the forest and when I have the opportunity to discover different regions of the world.


Partner & Director of the Quali & Sémio division
A former student of the Ecole Normale Supérieure, with a literary background, I started a university career in ancient literature before bifurcating into the profession of studies, and enjoying applying methods from the Human Sciences to this “living” field of consumption: deciphering signs, understanding their place in a history or cultural geography, and elucidating their social value.
Trained in qualitative studies and semio by Sorgem, I was able to support emblematic French brands in the management of their heritage (Michelin, Club Med, Canal Plus...), as outsiders capable of renewing consumption (Leboncoin).
I joined h2\ as a partner, to create the quality division and to develop my vision of semio, which is both “fundamental” and directly useful to decision-makers.
Founder & Innovation Director
I started my career as a copywriter and designer in Paris, then spent more than ten years in music production and image composition. This detour taught me how to structure stories and to understand the mechanics of professional production.
Arriving in marketing studies, I developed immersive rendering formats (ethnographic films, interactive narrative presentations) that transform insights into engaging experiences. I then designed collaborative digital platforms dedicated to research professions, then extended this expertise to other sectors via UBYX, a structure that I founded.
Since 2022, I have been leading the integration of AI at h2\, by designing augmented intelligence systems that amplify human expertise rather than replace it. This conviction structures our approach: placing human judgment at the heart of each device.


Director of International Studies
I was born and raised in the United States, but left the United States over eighteen years ago, driven by my passion for foreign languages and cultures. Since then, my career between the United States, Europe and South America — and the practice of several languages (English, French, Portuguese, Spanish...) — have nourished in me this profound curiosity, attentive to cultural and societal nuances.
I was trained in qualitative studies in France (Sorgem, MSM/June Marketing), but am also certified in Ericksonian hypnosis. In studies as well as in my practice in a therapeutic office for 8 years, I have been exploring the psychological and emotional dimensions of individual behaviors and beliefs. This interest in “what is happening under the surface” guides my approach to studies and advice: understanding what is being expressed, what is hidden, and what really creates preference.
At h2\, I support large groups and emerging brands on international markets, by translating these human dynamics into actionable strategic levers.

We made the strategic choice to develop and operate our own private technical infrastructure, controlling every link in the chain. This choice guarantees us total control of our processes and the maximum degree of sovereignty over the data you entrust to us, which the “black boxes” of public platforms do not allow.
Our compliance with the GDPR is not a simple administrative formality, but a proactive approach integrated into our daily practices. We apply strict procedures, such as the systematic signing of data processing agreements (DPAs) with our partners and the implementation of rigorous technical and organizational measures (TOM), which positions us among the most advanced players in the sector on these topics.
