Its underlying technical stack spans terrestrial, underground, aerial (drone), and bathymetric data capture, with downstream point-cloud processing and BIM deliverables.

The firm is owned and operated by four managing partners (Emmanuel Simon-Barboux, Jérôme Haxaire, Julien Cahart, Antoine Diot), all members of the Ordre des Géomètres-Experts, with senior roles in UNGE and the Yvelines Chamber of Surveyors. It serves a diversified customer base including private property owners, notaries, real estate developers and major corporates (Bouygues Immobilier, Vinci, Eiffage, Cogedim, Nexity, Kaufman & Broad, Carrefour, Auchan, Renault, Sanofi), municipalities and intercommunalities, and environmental bodies such as the PNR de la Haute Vallée de Chevreuse. Revenue is generated on a project-based professional services model with free quote-based engagement; pricing is not publicly disclosed and revenue figures are not published.
