What Startec Energy does

Startec Energy is a privately-held French industrial holding company founded in 1998 by Thomas Debuisser, headquartered in Mérignac near Bordeaux, with operations consolidated through three wholly-owned subsidiaries. Neogy designs and manufactures custom and adaptable intelligent lithium batteries ranging from 12V to 1000V and up to several MWh, serving electric mobility, marine, defense, aerospace, robotics, and stationary storage applications, with a 3,000 m² megafactory in Pompignac commissioned in May 2024 delivering 500 MWh/year of automated production capacity. BMS PowerSafe provides Battery Management System electronics ranked in the European TOP3, producing over 100,000 electronic cards per year for battery safety and performance, while Clairitec delivers Human Machine Interface (HMI) displays, including 100,000 units delivered to Medtronic for medical applications, and energy conversion products (DC/DC, MPPT, AC/DC chargers) under the Selfenergy sub-brand. The Belios sub-brand extends into off-grid solar batteries using proprietary Ni-MH and LiFePO4 chemistries.

The business model is B2B enterprise sales-led, targeting industrial OEMs and major groups through direct sales teams and dedicated key account management. Revenue is generated through hardware sales of custom-designed batteries and electronic systems, supplemented by R&D engineering services and industrial production services, with quote-based pricing on multi-year contracts. The group serves a diversified enterprise customer base including Renault, Nissan, Valeo, Safran, Ariane Group, Engie, Total Energies, SAFT, Medtronic, Tata Group, and Vision Marine Technologies. The company is the first French battery manufacturer to obtain ECE R100 homologation for electric vehicles (2019) and operates under ICPE 1510 industrial safety compliance, providing regulatory moats in automotive and stationary applications.

Geographically, all operations are currently domestic to France (Gironde / Nouvelle-Aquitaine region), with emerging European reach via strategic partnerships including Verkor (battery cell supply, targeting 1 GWh/year by 2030) and Vision Marine Technologies (marine battery production). The group was selected for the French government's ETIncelles program (4th cohort, November 2024) to support its transition from SME to intermediate-sized enterprise (ETI) status. Revenue stood at €10 million in 2024 across approximately 100 employees, with the new Pompignac factory representing the primary engine for future scaling.
