What St Groupe - Stts does

ST Groupe - STTS is a French privately-held specialty contractor founded in 1997 by brothers Frank and Stefan PLACHETKA as SUD TENNIS, rebranded to ST Groupe in 2005, with the STTS subsidiary added in 2014 to serve northern France. Headquartered in Boisseron (Languedoc) with a second operational base in Cormontreuil (Reims area), the company specializes in the construction, renovation, and maintenance of sports, industrial, parking, and safety flooring across the entire French territory. Its core offering covers the full sports-surface stack: tennis courts (porous concrete, GreenSet synthetic resin, Masterclay patented synthetic clay, synthetic grass, needlepunch carpet, and traditional clay); gymnasium floors (Pulastic poured resin from SIKA, Gerflor Taraflex PVC, Junckers and Connor Sports wooden parquet systems); large synthetic-grass fields (football/rugby) via an exclusive Italgreen partnership; and multi-sport, EPDM safety, industrial, and parking surfaces.

The company operates a project-based revenue model with quote-based pricing, complemented by recurring maintenance contracts (brushing, refilling, decompaction) on synthetic grass installations. Distribution is entirely direct and field-based: a national network of charged d'affaires (business managers) provides on-site consultation, technical advice, and quotations, with installation delivered by teams specifically trained by partner brands. Customer segments are diversified across French municipalities, sports clubs and associations, educational institutions (including CREPS Olympic training centers and universities), private commercial facilities, and industrial clients. The business claims market leadership in French sports floor installation, holds federation-granted certifications (PQT, Qualisport, NF, Qualibat), and operates at a scale of approximately 650+ realizations per year with ~100 employees.

Revenue is not publicly disclosed; the company is family-owned with no external institutional investors, no funding rounds, and no M&A activity on record. Forward signals point to incremental rather than aggressive expansion: deeper industrial segment reinforcement (SEPT-RESINE team, 2018), continued national coverage via regional agencies, and an emerging recurring maintenance revenue layer atop the predominantly one-time project base.

Product overview

ST Groupe is a specialist construction and renovation company for sports and industrial floors, operating as a single unified service offering rather than a software platform.

The company also installs synthetic grass for large game fields through its ITALGREEN partnership. Industrial and parking floor solutions form a secondary line.
