Sepia Signage

What Sepia Signage does

Sépie Signalétique (Sepia Signage) is a French visual communication and signage company founded in 2004 and headquartered in Échirolles, in the Grenoble basin. The company designs, manufactures, and installs custom exterior and interior signage, road signage, business signs and totems, 3D relief lettering, vehicle branding, window stickers, and advertising banners for enterprises, public institutions, and event organisers. Its portfolio of named clients includes CEA, Crédit Agricole Sud Rhône-Alpes, La Poste, STMicroelectronics, Soitec, Colas, Eiffage, Eurovia, and Grenoble-Alpes Métropole.

The company operates from a multi-thousand-square-metre workshop in Échirolles using HP Latex water-based large-format digital printing, CNC cutting and routing, large-volume 3D printing and machining of polystyrene, and 100% recyclable technical cardboard printing. Through its 2017-created wholly-owned subsidiary Déko 3D by Sépia, Sepia extends its offering into oversized 3D marketing displays and event installations.

The business model is a direct, quote-based project model: customers request a free quote (devis sous 48h) via phone, email, or the website, and each engagement is managed end-to-end by a dedicated project manager from site audit and graphic design through in-house fabrication to certified on-site installation. Pricing is entirely custom; no tier or subscription pricing exists. The go-to-market is sales-led, relying on the website (sepiasignaletique.fr), organic social media, downloadable catalogues, and word-of-mouth within the local business and institutional community, with no paid digital advertising identified. Geographic focus is the Isère department (Grenoble, Voiron, Bourgoin-Jallieu, Vienne) with capacity to study projects in neighbouring departments of the Auvergne-Rhône-Alpes region.

• Aximum: Road signage and traffic management subsidiary of Colas, providing road signalling, urban furniture, and safety equipment across France. Directly competes with Sepia in the road signalling and urban-development segment Sepia serves (Colas, Eiffage, Eurovia are also shared enterprise customers).
