OUR STORY

LEROY Automation – a member of the AGÔN Electronics group since 2022 and initially known as LEROYAutomatique Industrielle – was founded in 1983 by Jean Leroy, who had spent around 12 years working for Merlin-Gérin (now Schneider Electric™) in Grenoble. Jean LEROY was a brilliant and passionate engineer who graduated from the École Nationale Supérieure des Mines in Saint-Etienne in 1967.

He led his company to success with visionary technologies and ideas that were at the leading edge of innovation, while steering it through rapid changes in the electronics and automation markets. For more than 20 years, he developed the company by designing and making input/output modules and programmable logic controllers (PLCs).

In the 2000s, the company changed its name to LEROY Automation™, which is now a globally recognised brand. He appointed Alain Wojtaszak, now CEO, who led the company’s transformation and its drive to specialise in niche markets. With his experience working at international industrial and automotive equipment makers, Alain took responsibility for the growth, innovation, and strategic development of LEROY Automation’s activities before handing over the reins to David VAYSSIE in 2025.

With its team of dedicated experts, this fast-growing company is now a major player in control and operation systems in international rail, energy, defence and manufacturing markets.
