What Alti City does

Alticity SAS (operating as ALTI CITY, formerly SAS Alpinistes Brestois du Bâtiment) is a French rope access and work-at-height services company founded circa 2000 in Brest and headquartered in Guipavas, Finistère. Since 2025 it has operated as the Brittany-focused subsidiary of Groupe Jarnias, the leading French group in difficult-access work. The company provides certified cordiste (rope access) services across three core service lines: Travaux Bâtiment (facade restoration, masonry, roofing, monument maintenance including churches, lighthouses, and water towers), Travaux Industrie (industrial maintenance, inspection, anti-corrosion treatment, welding, lifting, electrical work at height for agribusiness, naval repair, wind energy, and telecoms), and Protection-Sécurité-EPI (permanent and temporary fall protection systems, lifelines, anchor points, safety nets, and personal protective equipment supply). It also offers specialized expertise including crane operations, wind turbine maintenance, campanology (bell tower maintenance), facade cleaning, silo maintenance, fire safety system installation (SSI), structural inspection, and event installations.

The underlying technology consists of rope access techniques executed by CQP-certified technicians supported by an owned fleet of cranes, aerial work platforms, and certified lifting equipment, combined with multiple regulatory certifications (QUALIBAT, ACQPA, Amiante 4, Licence 111, Plomb) and B Corp certification at the parent group level. Alticity is differentiated from traditional scaffolding contractors by its ability to access complex structures without scaffolding disruption, including sensitive environments such as military, naval, and historic monument sites.

The business model is project-based professional services: each engagement is custom-quoted based on scope, complexity, height, and duration, with no publicly disclosed pricing tiers. Go-to-market is direct field sales via phone and contact form, with no intermediaries, resellers, or marketplace channels. The company operates four regional offices in Brittany (Guipavas, Hennebont, Trégueux, Ergué-Gabéric) to serve building owners, industrial operators, local authorities, and construction firms across the Grand Ouest region, with national deployment capability. The parent group's broader footprint (28 implantations across France, Switzerland, Africa, and the Indian Ocean) provides referral, training, and cross-sell leverage not available to standalone competitors.
