✨ Holotech Industry

Our mission: to make available innovative tools that promote emotional balance, deep relaxation and reconnection with oneself – for therapists and individuals alike.
👤 Pierre Griffoin, co-founder and managing director
Pierre Griffoin is an entrepreneur and health practitioner. After an initial career as a project management specialist, he trained in various health practices, notably chromotherapy and sophrology. Today, he is guided by a strong personal experience after having experimented with Holopsonie for himself, clients, his sons and other loved ones.
Convinced by the positive effects of Holopsonie, Pierre wanted to preserve and develop this unique method, by making it more accessible.
That’s how he decided to create Holotech Industry, to modernize and restart the production of equipment that hadn’t been manufactured for 10 years.

🎧 A method based on a visionary duo: Bourdin & Bouchet
Holopsonie was created in 1985 by Dominique Bourdin, an energy therapist, and Jean Bouchet, an engineer and equipment designer. Together, they developed an innovative method at the crossroads of neuroscience, active listening and energy healing.
- Jean Bouchet, who began his professional life as an electronics engineer for Alfred Tomatis, designed and developed the original software for the first Holopsones.
- Dominique Bourdin, a health practitioner with a doctorate in Medicine, has been offering Holopsonie for almost 30 years in his health practice, now the wellness center La Chrysalide – renamed the Centre de Bien-Être du Jaunay. The method continues to be practiced there.
🛠️ A vision for tomorrow
With Holotech Industry, Pierre Griffoin continues this tradition by modernizing the equipment:
“Our ambition is to produce high-performance, reliable and affordable equipment, while remaining faithful to the principles of Holopsonie, and continuing to improve the method in terms of both use and equipment.
🌿 A human and open approach
We believe it’s possible to unite science, intuition and accessibility.
Holotech Industry is a project born of a deep conviction: well-being through the senses is a universal path. We’re delighted to make it accessible to as many people as possible.
