ALTAÏS Groupe

What ALTAÏS Groupe does

ALTAÏS Groupe is a privately held French SARL founded in 2004 and headquartered in Courbevoie, operating a multi-trade construction services platform across the Île-de-France region through five wholly-owned subsidiaries: ALTAÏS ATAD (difficult-access rope work), ALTAÏS ACE (roofing and waterproofing), ALTAÏS ACDE (space creation and interior fit-out), ALTAÏS ASM (locksmithing and metalwork), and ALTAÏS ARE (facade restoration and scaffolding). The group serves property owners, managers, and businesses — including named references at Google, SNCF, Tour Eiffel, AXA, EDF, and the Opéra de Paris — on projects ranging from traditional Parisian zinc/slate roof restoration to industrial maintenance, interior fit-out, custom metal fabrication, and high-rise facade work executed by certified cordistes.

The underlying technical base is craft-driven rather than digital: specialized rope-access techniques derived from speleology and alpinism enable work in confined or elevated spaces; in-house metal fabrication covers TIG/MIG welding, machining, drilling, forming, and grinding; and the group bundles scaffolding, masonry, waterproofing, painting, and finishing under one operating umbrella. Field operations are supported from a dedicated workshop in Colombes, while commercial, direction, and administrative functions are housed at the Courbevoie headquarters.

The business model is project-based and quote-driven: revenue is generated through multi-year contractual engagements for one-off construction, renovation, and maintenance scopes, priced on materials, labor, and complexity. With approximately 100 employees across five entities, capital of €510,000, and no external investors disclosed, the group positions itself as a human-sized B2B SME that competes on craftsmanship, multi-trade integration, and proximity to clients rather than on scale or technology differentiation. It is controlled by three co-founders: Julien BARRE (CEO, founder of the original rope-access business), Stéphane MORIN (CEO of the roofing entity), and Dorin MORARU (founder of the interior fit-out entity, joined 2015).
