ETABLISSEMENTS STNI

What ETABLISSEMENTS STNI does

ETABLISSEMENTS STNI (Société de Travaux Nettoyage Industriel) is a family-owned cleaning services company headquartered in Ferrière-la-Grande, Hauts-de-France, France, founded in 1997. The company provides professional cleaning services to both B2B clients (offices, schools, shops, industrial sites, transportation operators, municipalities) and B2C clients (residential customers, post-move cleaning, decluttering). Its service portfolio spans at least 12 specialized categories including tertiary cleaning, industrial cleaning, common areas maintenance, window cleaning, facade cleaning, parking maintenance, post-construction restoration, post-disaster cleaning, disinfection, and debris removal. A sub-brand called STNI Express delivers 24/7 emergency response for water damage, fire damage, and unsanitary premises.

STNI operates with approximately 27 employees and a fleet of geolocated vehicles supporting rapid deployment across the Nord department. The technology stack is conventional: standard cleaning equipment and professional-grade products, with quality control delivered through a three-level methodology (periodic control, self-control, annual audits) rather than software automation. No proprietary technology, AI capabilities, software products, or digital platforms are disclosed.

The business model is professional services revenue, generated on a quote-driven basis through a "Devis" request form on the company website and direct outreach. Pricing is custom per engagement, with multi-year contract structures supporting enterprise clients. The company markets minimally, relying on its website, word-of-mouth, and a visible client logo wall that includes Ford, Colas, Suez, SNCF/TPS, and the city of Maubeuge. Operating geography is confined to the Nord department of France, and the company has not raised external funding, maintains no subsidiaries, and reports no M&A or leadership transitions in the available source material.
