"Promoting French industrial excellence to support electric transition”


Founder / CEO

For nearly 25 years, I have made it a point of honour to promote French know-how. It is with this in mind that I have created at Startec Energy® a real centre of expertise in French engineering. To support industrialists and accelerate the development of electricity, I advocate quality and technological innovation, which guarantee industrial excellence.

Location of our sites

A French group, all Startec Energy® sites are located in France. Created in the Aquitaine region (33), the group has naturally developed around the Bordeaux metropolis.

1500 M2

Less than a kilometre from Mérignac international airport and close to Bordeaux, the group built its headquarters 15 years ago. On this 1500m2 site, Startec Energy® groups together the support and administrative services as well as all the engineering services of the group. With around 100 employees, all companies and brand is represented here. In a nearby building, Startec Energy® also keeps a part dedicated to prototyping and pre-series production, close to the R&D teams.

3000 M2

Currently under construction, the Pompignac site will house a brand new factory by the end of 2023. Through its subsidiary Neogy, the Startec Energy® group will assemble medium and large series battery packs. Equipped with production lines and located in the immediate vicinity of Bordeaux, this 3,000m2 site will enable the group to respond to the growth of electric power and the growing needs of industrialists. With an expected production capacity of 500 MWh, this new plant will enable the group to meet all electrical needs, whatever the sector of activity.

Startec Energy® has 25 years of experience. 25 years of research and development, technological innovation and engineering expertise. 25 years at the service of the energy transition and progress. But behind this number, Startec Energy® is above all an adventure, a story. A story that had to be written, driven by the convictions and ambition of Thomas Debuisser, CEO and founder of the group.
  1. 1998 Creation of Clairitec

    The company was founded by Thomas Debuisser as an electronic engineering design office. Like the American success stories, it was in a garage converted into an office that the adventure began. The head office was then located at his home in Saint Jean d'Illac (33). Alone at the beginning, two collaborators joined the start-up and Clairitec carried out its first studies for companies in Gironde.

  2. 2002 - 2006Development of the company

    After four years of activity, the demands were flooding in and the family garage was no longer sufficient. Clairitec moved to Mérignac (33) in 2002 and created a test and design workshop for small series. In 2006, its know-how was recognised and the company received ISO 9001 certification, which rewards the excellence and continuous improvement established since the company's creation

  3. 2007-2009Business developmen

    Ten years after its creation, the company specialises in developing its own range of graphics cards. A division is dedicated to the design of Human Machine Interfaces (HMI). At the same time, T. Debuisser joined forces with Venturi to create the company "Ventec" in 2009. First steps in the battery sector, the objective is to develop a new generation of electronic battery management systems (BMS).

  4. 2015-2016Creation of the Startec Energygroup and Neogy

    2015 is an important year, the Startec Energy Group is created in order to facilitate the exchange of skills and knowledge between the two companies Clairitec and Ventec. The following year, Neogy, a company dedicated to the design and production of electrical energy storage systems, was created. At the same time, the group moved to the site that would become its headquarters, in Mérignac (33).

  5. 2017The group joins the race for electrification

    The group's growth accelerates and takes a new turn. In 2017, with the rise of electric vehicles, the group is focusing its activity on battery and energy conversion technologies.

  6. 2019Structuring to respond to the growth of electric vehicles

    Fully committed to electric vehicles, Startec Energy becomes the majority shareholder of its BMS design business in 2019, Ventec then becomes BMS PowerSafe. At the same time, Neogy became the first French battery manufacturer to obtain ECE R100 approval for a battery for M1 and N1 category electric vehicles (including fire and crash tests).

  7. 2020The rise of Neogy, the heyyear of Clairitec

    Neogy continues its rise. With the recognition of its know-how, the company is signing new contracts and has completed more than 40 studies in four years. Neogy is multiplying its applications and diversifying the technologies used, whether for batteries for agricultural, automotive, aerospace or electrically assisted bicycles. At the same time, Clairitec is celebrating the delivery of its 100,000th HMI card in the medical sector.

  8. 2022A strong industrial character

    The group writes a new page in its history, almost 25 years after its creation. St@rtec Developpement is disappearing to become Startec Energy®. A new identity better suited to its activities and its ambition. The group is now asserting its industrial character and its production capacities, notably with the construction of a new production plant near Bordeaux through its subsidiary Neogy.

  9. 2025Tomorrow

    Under its new identity and armed with its new production site, the group is now in a position to meet the challenges of industrialists and large groups. It is addressing new markets and larger volumes to respond to societal changes and the democratisation of electricity. In 2025, the group's industrial positioning will lead it to set up new production sites


From prototype to mass production, Startec Energy® has accompanied hundreds of clients in all their projects. From start-ups to large industrial groups, it is thanks to a privileged and long-lasting business relationship that we mutually grow our organisations.
