What Katene does

Katene is a French workers' cooperative (SCOP) engineering consultancy specializing in environmental building design, founded in 2008 and headquartered in Vaulx-en-Velin (Lyon metropolitan area). The firm delivers integrated multi-discipline engineering services across six competence areas: HVAC engineering (Génie Climatique / CVC), electrical engineering (Génie Électrique / CFO), aquatic center engineering, energy and environmental performance (HQE, BREEAM, BDM, EFFINERGIE certifications), building fire safety (sprinkler engineering and SSI coordination), and construction execution monitoring. Katene applies Building Information Modeling (BIM), numerical simulation, and multi-discipline integration to design complex technical systems for buildings, with particular depth in aquatic centers, pharmaceutical confined laboratories, and nuclear-sector facilities.

The company serves both public sector clients (Métropole du Grand Paris, Académie Aix-Marseille, Hôpital Nord-Ouest) and private enterprises (EDF, Crédit Agricole Immobilier, Sanofi-Pasteur, Immochan) across France through project-based commissions and responses to public tenders. Notable engagements include the €111 million Centre Aquatique Olympique for Paris 2024 (NF HQE certified) and a €300 million 6-year framework contract with EDF Partner France for renovation of nuclear tertiary buildings across 11 CNPE sites. Katene operates from three offices: Vaulx-en-Velin (headquarters), Meyreuil (Katene Sud), and Paris (Katene Paris), covering the Auvergne-Rhône-Alpes, Provence-Alpes-Côte d'Azur, and Île-de-France regions.

Revenue is generated through fee-for-service engineering consultancy engagements, with fees negotiated on a project-by-project basis consistent with French engineering practice. The cooperative ownership model, in which employees can become associates after one year and acquire company capital, structurally aligns talent retention with long-term client delivery. Go-to-market is sales-led and reputation-driven, relying on a portfolio of reference projects, professional website presence, and industry referrals rather than active digital marketing channels. No revenue, headcount, or external funding data is publicly disclosed.

Core offering

Katene is a French cooperative engineering consultancy (bureau d'études de conception environnementale) that designs and supervises the technical systems of buildings. It delivers six interconnected engineering service lines — HVAC (Génie Climatique), electrical (Génie Électrique), aquatic centre engineering (Ingénierie des Centres Aquatiques), energy and environmental performance (including HQE/BREEAM/BDM/EFFINERGIE certification), building fire safety (sprinklage and SSI coordination), and construction execution monitoring (Suivi de travaux) — to public and private project owners across France.

Product overview

Katene is a cooperative environmental engineering design consultancy providing comprehensive engineering services for building projects. The company operates as a unified service offering across six interconnected competence areas: HVAC Engineering (Génie Climatique), Electrical Engineering (Génie Électrique), Aquatic Center Engineering (Ingénierie des Centres Aquatiques), Energy and Environmental Performance (Performance Énergétique et Environnementale), Building Fire Safety (Sécurité Incendie des Bâtiments), and Construction Execution Monitoring (Suivi de l'Exécution des Travaux). These services are delivered together as an integrated engineering consultancy rather than as discrete software products or modules, serving public and private clients across diverse building typologies including aquatic centers, educational facilities, healthcare, residential, commercial, and industrial projects.
