What Geolithe does
Geolithe (legal entity: GEOLITHE SAS, registered in Grenoble, France) is an engineering consultancy founded in 1992 in Crolles, Isère, providing specialized services in geology, geophysics, geotechnical engineering, environment, and civil engineering. The company operates three interconnected business divisions: GÉOLITHE INGÉNIERIE (core engineering consulting for natural risk studies, geotechnical analysis, hydrological modeling, structural engineering, and emergency response), GÉOLITHE INNOV (R&D subsidiary created in 2016, developing proprietary tools such as the EVORISK digital-twin surveillance platform, GéoCO2 eco-design carbon accounting tool, RFID-based landslide monitoring, and the KONTUR Mk6 3D frequency-hopping ground-penetrating radar), and GÉOLITHE FORMATION (training subsidiary launched in 2024). The firm also owns Hydrophy, a hydro-physics services subsidiary acquired in 2019. Geolithe conducts joint research with ISTERRE (Université Grenoble Alpes and Université Savoie Mont Blanc) through the GEO3ILab Joint Laboratory established in 2019, and participates in ANR-funded research projects including C2R-IA (AI-based rockfall risk management) and DOLMEN (masonry bridge behavior). Technical operations are delivered through 13 regional agencies covering all metropolitan France and 4 overseas territories (Réunion, Mayotte, New Caledonia, French Polynesia), supported by 180 staff including 120 engineers and PhDs, 25 certified drone pilots, and specialized rope-access/confined-space intervention teams.
Geolithe generates revenue exclusively through professional services delivered under bespoke, project-based contracts priced per scope, duration, and technical complexity, with no public pricing or subscription model. Its primary customer segments are public-sector territorial authorities (départements, régions, municipalities, metropolises), critical infrastructure operators (SNCF Réseau, EDF, airport authorities), and private engineering firms that subcontract specialized geoscience studies. Natural-risk work represents more than 50% of activity. Demand is captured through direct field sales via regional agency teams, public tenders, and emergency procurement, with 7-day-a-week emergency intervention availability. The firm holds ISO 9001, ISO 14001, ISO 45001 certifications, OPQIBI qualifications across multiple disciplines, and MEDDE approval for hydraulic structures (dams, dikes). In 2025 Geolithe became a société à mission and in late 2024 opened its capital to employees, resulting in 55 of 180 staff becoming shareholders alongside 8 historical shareholders; no external private equity or venture capital is reported in the source material.
