What Altempo does

Altempo SAS is a French provider of provisional modular buildings and integrated construction site management services, headquartered in Bennwihr-Gare, Alsace. Founded in 2003 by Thierry Munier, the company designs, installs, rents, and decommissions temporary modular structures — including school buildings, nurseries, offices, and construction site base camps (bases-vie) — for French public-sector institutions, major construction project owners, and a limited set of private enterprises. Since January 2020, Altempo has operated as a wholly-owned subsidiary of Algeco, the global modular construction leader, while retaining operational autonomy in developing its all-trade provisional activities.

The company's core differentiator is the integration of physical modular infrastructure with a proprietary digital platform, ALTGENI, which coordinates site logistics, access control, worker safety induction, digital welcome booklets, and real-time monitoring across multi-stakeholder construction sites. The product portfolio spans physical offerings (Tempo'Crèche modular nurseries, modular schools, temporary offices, fencing, signage, recoverable foundation systems achieving a 95% material recovery rate), digital solutions (ALTGENI, Opti'tempo for nursery occupancy optimization, Tempo'Synch for constrained-site synchronization, digital welcome booklets, digital access control), and full-service site management (maintenance, security, cleaning, logistics, catering). The circular economy model enables modular components to be redeployed across projects, supporting both environmental positioning and cost efficiency.

Altempo generates revenue primarily through long-duration modular building rental contracts supplemented by managed service add-ons (security, cleaning, maintenance, logistics) and emerging software licensing streams for ALTGENI and Opti'tempo. Distribution is entirely direct enterprise sales via technical sales engineers and public procurement tenders; no intermediaries or reseller channels are used. The customer base is concentrated in French public-sector institutions including RATP (with a 78-month management contract on Line 4), SNCF, Mairie de Paris, Assemblée Nationale, Musée du Louvre, Château de Versailles, Opéra de Paris, and Philharmonie de Paris. Annual revenue is approximately €30 million across 82 employees, with operations concentrated in Alsace and the Île-de-France region but with documented national project coverage.
