OTEGO, a subsidiary of the French industrial group OTEGO (nearly €30 million in revenue, 100 employees, present in 110 countries), a global leader in technical textiles in its markets (rubber industry and heat protection for people and equipment ), announces the majority acquisition of Calomatech, a specialist in industrial thermal insulation.
This operation comes at a time of intense energy pressure on industrial sites and marks a key milestone in OTEGO's growth strategy. The goal is to rapidly and sustainably reduce heat loss and the carbon footprint of industrial companies in France and internationally.

A tense market, an immediate energy challenge for industry
Faced with the sustained rise in energy costs and growing decarbonization requirements, manufacturers are seeking concrete, rapidly deployable, and measurable solutions to improve the energy performance of their facilities.
It is in this largely untapped source of savings that OTEGO is now accelerating its development.
OTEGO accelerates its measurable energy performance strategy
Specializing in the design and manufacture in France of high-performance textile solutions, OTEGO protects people and machines in demanding industrial environments.
With its "CAP 2030" strategic plan, the group is evolving its positioning, combining operational excellence and environmental innovation: moving from materials to measurable industrial performance, combining protection, energy efficiency, and a concrete reduction in its customers' carbon footprint.
In 2024, OTEGO carried out a capital transaction with its long-standing investors (GENEO Capital Entrepreneur, Eximium, and Bpifrance) in order to secure the resources needed to develop new activities related to current climate challenges.
The takeover of Calomatech is fully in line with this trajectory.
Calomatech: turnkey thermal insulation solutions, from the ground up to the digital realm
Founded in 2017, Calomatech works directly at the heart of industrial facilities to reduce heat loss, improve operator safety, and generate rapid and quantifiable energy savings.
The company deploys turnkey industrial thermal insulation solutions, from design to implementation, drawing on recognized field expertise. These solutions are already in use at leading industrial sites in a variety of sectors, includingagri-food, pharmaceuticals, and shipbuilding, for groups such as Sanofi and Total.
This operational approach is based on a database of more than 50,000 technical data points from industrial sites, a digital tool that enables remote studies to be carried out using field photos, and deployment times reduced to 8 weeks.
With Calomatech joining the group, OTEGO intends to accelerate the digitization of these turnkey solutions by 2027, in order to streamline decision-making and strengthen the measurable energy impact for manufacturers.
Governance and development in France and internationally
As part of the transaction, OTEGO becomes the majority shareholder of Calomatech. Its founder, Gwenaël Breton, remains a partner and retains his position as Chief Executive Officer, ensuring operational continuity, field expertise, and a culture of customer focus.
Following this merger, the OTEGO group is proud to maintain 100% French production (OTEGO: Lyon, Calomatech: Caen and Marseille), while continuing to pursue a "glocalized" approach with a commercial presence on five continents (85% of turnover generated by exports). Calomatech's expertise is a growth driver for OTEGO in industrial markets with high demand for low-carbon solutions.
In the short term, development will focus on Europe (Spain, Italy, Belgium, Ireland), before gradually rolling out in North America and Asia, leveraging the group's international presence.
"With Calomatech, we are moving from a product-based approach to one focused on energy performance
measurable, directly on industrial sites. This is a key step in our CAP 2030 plan."
Thierry Mosa, President of the OTEGO Group
"Joining the OTEGO group will enable us to accelerate our international development, while strengthening our innovation and industrialization capabilities."
Gwenaël Breton, CEO of Calomatech
