Kalies

What Kalies does

Kalies is a French environmental and industrial-risk consulting firm founded in 1998 and headquartered in Lezennes (Lille metropolitan area), operating as a SAS with approximately 50 employees. The company advises industrial clients, local authorities (collectivités), and real estate developers on two core service lines: (1) regulatory dossier preparation for ICPE (Installations Classées pour la Protection de l'Environnement) sites, including environmental authorization applications, impact studies, water law dossiers, ATEX diagnostics, atmospheric dispersion modeling, acoustic measurements, and compliance audits, and (2) polluted sites and soils (Sites et Sols Pollués) studies delivered in conformance with the French NF X 31-620 standard, covering diagnostic studies, remediation planning, environmental monitoring, and rehabilitation engineering. Since founding, Kalies reports it has completed more than 1,800 environmental authorization dossiers, 900 soil pollution studies, and 200 cessation-of-activity reports.

The firm is the lead entity within the Groupe Kali ecosystem, alongside Kali'air (air quality), Kali'eau (water), Kali'bio (biodiversity), and Perl Environnement (site transactions), collectively employing ~140 collaborators. Kalies itself is distributed across a headquarters and 8 regional offices covering Nord, Est, Ouest (Bretagne and Normandie), Auvergne-Rhône-Alpes, Sud-Est, Île-de-France, and Sud-Ouest, enabling national coverage with local presence. Its revenue model is professional services — quote-based, project-by-project B2B engagements — and pricing is not publicly disclosed. Named clients span more than 11 industries and include Air Liquide, Sanofi, Veolia, Suez, Eiffage, Bouygues, SNCF, Safran, Bel, Roquette, and PSA Group, alongside local government clients such as the Communauté de Dunkerque and the Communauté de Cambrai.

The company is privately held with no disclosed external funding, no M&A activity, and no international expansion. Its principal intangible assets are its NF X 31-620 certification, UPDS membership, 26 years of dossier track record, and the cross-disciplinary reach provided by the broader Groupe Kali. There are no indicators of AI/ML capability or proprietary technology platforms; the offering rests on credentialed engineering labor and regulatory expertise.
