Cerenn

What Cerenn does

Cerenn is a French manufacturer and installer of modular partition systems and autonomous office pods, headquartered in Levallois-Perret (Île-de-France) with two owned production facilities in Rimaucourt (Champagne-Ardenne) and Sarre-Union (Alsace). Founded over 100 years ago and organized as a Société par actions simplifiée (SAS) with €594,750 in share capital, the company is privately held by French entrepreneurs with no disclosed venture capital or institutional investor involvement. Cerenn operates a 51–100 employee organization delivering project-based, custom-engineered solutions across six branded collections: Arpège (simplicity-focused aluminum glazed partitions), Émergence (high acoustic performance aluminum and steel partitions with edge-to-edge glass), Ulteem (90mm steel partitions achieving up to 53 dB RA acoustic performance), Atol (autonomous acoustic pods for 1–6 people in BORA and MAHÉ configurations with silent integrated ventilation), Cekens (EI 60 fire-rated demountable partitions up to 4 meters high), and In fine (functional accessories).

The company's underlying technology centers on proprietary acoustic engineering (up to 53 dB RA), certified fire safety (EI 60 European standard), demountable/modular construction (enabling the reuse service that accounts for roughly 20% of activity), and high-ceiling capability (up to 4.5 m). Vertically integrated R&D, project-specific engineering studies, installation, and site management teams execute the full value chain from concept through delivery.

Cerenn generates revenue through one-time, quote-based enterprise sales of custom partition and pod solutions, with multi-year contract cadences typical for major fit-outs. Its go-to-market is direct enterprise field sales, complemented by named export sales managers serving international markets beyond France. Customer segments span corporate offices and commercial buildings across insurance (Groupama, Crédit Agricole, Société Générale, BGL Luxembourg), energy (EDF), IT services (INETUM), scientific research (Medpace France), and construction (FFB), with marquee projects including the 65,000 m² INETUM Stories campus and the 15,000 m² Groupama community building. In 2025 Cerenn opened the first B-to-B platform for removable partition components in the Lyon region, signaling a move beyond pure project delivery toward recurring component distribution.
