AET Group

What AET Group does

AET Group is a French industrial thermal equipment designer and manufacturer headquartered in Grenoble, founded in 1968. The company designs and builds high-temperature furnaces, vapor phase soldering systems, induction heating platforms, and VCSEL oxidation equipment through its subsidiaries AET Technologies, PYROX (formerly Pyrox), Aloxtec, and ID Partner (joined July 2025). Its products serve process-critical applications in microelectronics, photonics, metallurgy, aeronautics, nuclear, ceramics, photovoltaics, chemistry, medical, and food processing, with installed units deployed across five continents.

The company's core technology stack spans proprietary high-temperature thermal engineering, precision atmospheric control, and process automation, underpinned by 50+ years of accumulated know-how and CEFRI nuclear-grade certifications. Aloxtec gives AET an estimated 60-70% world market share in VCSEL oxidation furnaces serving photonics and infrared detector manufacturers, while the broader group positions as the European leader in hot mechanical testing furnaces for steel and advanced materials research. Equipment unit pricing spans roughly €100K to €2M+ depending on configuration, with recurring revenue from maintenance contracts on an installed base exceeding 5,000 units.

AET Group generates revenue through a sales-led, quote-based go-to-market model targeting large industrial groups and public/private R&D centers. Named customers include CEA, CNRS, STMicroelectronics, and Arcelor, alongside undisclosed global semiconductor, steel, and infrared detector leaders. Two-thirds of the 450-client base is composed of R&D centers, with maintenance and service contracts providing recurring revenue on the installed fleet. The company is backed by Yotta Capital Partners (investment 2021) and has pursued a consolidation strategy that brought all subsidiaries onto a single Grenoble site by 2022, with mass recruitment planned over a 4-5 year horizon.
