What NST Group does

NST Gruppen is a privately-held Norwegian conglomerate of small operating companies founded in 1995 by CEO Jan Thorstensen, headquartered in Avaldsnes on Karmøy with a regional office in Vilnius, Lithuania. The group delivers personnel staffing, construction services, industrial surface treatment, scaffolding, cleaning, property management, healthcare, and accounting/consulting services through seven wholly-owned subsidiaries: NST Contracting AS (scaffolding, industrial cleaning, surface protection for shipyards, offshore rigs, and heavy industry), NST Byggservice AS (concrete/facade renovation, flooring, painting, tiling, masonry, carpentry), NST Renhold AS (cleaning, gardening, janitorial, facility services), NST Eiendom AS (property management), UAB NST Baltija (temporary/permanent staffing plus healthcare services under Lithuanian Health Care Licence No. 3249), UAB NST Accounting (accounting and consulting), and NST Andalucia S.L (facility management in the Marbella area). The business model is B2B professional services priced on a project-by-project basis for enterprise and public-sector clients, with a cross-border staffing mechanism that recruits personnel through Lithuanian and Spanish offices for deployment primarily in Norway, with secondary operations in Lithuania and Iceland.

The group's underlying technology is industrial rather than digital: owned scaffolding, ultra-high-pressure cleaning systems, sandblasting apparatus, and surface-inspection capability certified to NS 476/FROSIO standards. NST Byggservice holds central approvals for carpentry, masonry, heritage-building work, and demolition/environmental sanitation, and is an approved training company in three trades; NST Renhold is an approved cleaning company registered with the Norwegian Labor Inspection Authority; and UAB NST Baltija's General Manager leads the Lithuanian Association of Temporary Employment Companies, an industry body co-founded by NST in 2007.

Go-to-market is sales-led and direct: enterprise framework agreements (notably Olav Thon Gruppen, extended to 2025), reference-project marketing through the company website in Norwegian, English, Lithuanian, and Spanish, attendance at international tile trade fairs (CEVISAMA, CERSAIE), and organic social (Facebook, Instagram). Customers span maritime and offshore (Saipem 7000, Solstad Offshore), energy (Gassco, Hydro Aluminium, Sør-Norge Aluminium), construction (Veidekke Bygg, GL Prosjektservice), healthcare (Haugesund Hospital, Haugesund Sanitetsforening), education (Unitech, Karmsund Videregående Skole), and government/heritage (Kopervik Kirke). The group is family-controlled with no external institutional investors, no disclosed funding rounds, and no public listing.
