Groupe Prenveille

What Groupe Prenveille does

Groupe Prenveille is a French family-owned electronics manufacturing services (EMS) conglomerate headquartered in Saint-Malo, formed through the 2019 unification of four specialized EMS brands under a single holding structure. The group operates four production sites across France totaling 10,500 m² of manufacturing capacity and employing approximately 240 people, with combined revenue of approximately €45M as of the group's 2019 formation. Its portfolio of wholly-owned subsidiaries includes ASICA (Saint-Malo, ISO 13485 medical specialty, €13M revenue, 80 employees), SICAP (Coudeville-sur-Mer/Granville, EN 9100 aerospace and defense, €10M revenue, 70 employees), CMS Industrie (Sainte-Foy-l'Argentière near Lyon, IRIS railway, €5M revenue, 70 employees), and PROMISTEL (La Chapelle-la-Reine near Paris, ISO 9001:2015 short-lead-time assembly). The group's origins trace to ASICA, founded by Loïc PRENVEILLE in April 1992, with the family continuing to control operations through Pascal PRENVEILLE as Director General.

The group provides a full-service EMS offering spanning electronic conception, routing, embedded software development, prototyping, industrialization, series fabrication, integration, wiring, and testing of electronic cards and assemblies. An internal Bureau d'Etudes of approximately 10 engineers delivers shared R&D and design services across the four brands, supported by methods services that handle AOI programming, NPI, continuous improvement, and lean manufacturing. The business leverages five core certification regimes — ISO 13485 (medical), IRIS (rail), EN 9100 (aerospace/space/defense), ISO 9001, and UL ZPVI2/ZPVI8 — that gate access to regulated end-markets and enable product exports to the United States and Canada.

The revenue model is project-based B2B subcontracting with pricing determined by complexity, volume, and specification rather than published rates. Customers include both large industrial groups and PME-PMI across aerospace, railway, industrial equipment, telecommunications, consumer electronics, and measurement/navigation sectors. Distribution is entirely direct, with dedicated sales engineers and chargés d'affaires acting as single points of contact from conception through series production. Group growth has been executed entirely through acquisitions and organic expansion, with no external funding rounds disclosed: SICAP acquired in 2016, CMS Industrie in 2018, and PROMISTEL in 2021.
