Fosstech

What Fosstech does

Fosstech AS is a Norway-based electromechanical production company headquartered at Borgeskogen in Stokke/Sandefjord, founded in 1997 by Steven Foss. The company engineers, encapsulates, and assembles electronics, cable harnesses, connectors, sensors, transducers, and electromechanical enclosures designed to operate reliably in extreme environments including subsea depths up to 600 meters, maritime and offshore installations, defense platforms, explosive atmospheres, and outdoor infrastructure exposed to severe weather. Core offerings span three integrated service lines (Development, Molding/Encapsulation, and Cables/Cabinets), a branded safety product (Omicron OAS, a type-approved level-alarm system for tankers), and an aftermarket service and re-certification business. Manufacturing and engineering are co-located in a single approximately 5,000-square-meter facility to support rapid prototyping and short development cycles for low-volume, high-mix serial production.

Fosstech's commercial model is relationship-driven enterprise field sales targeting demanding customers in maritime, defense, subsea, infrastructure, healthcare, and aquaculture. Revenue streams include serialized hardware product sales, product-development engineering services, and recurring service, maintenance, and re-certification contracts. The company holds ISO 9001, 14001, and 45001 certifications with ISO 27001 implementation in progress, and its Omicron OAS is type-approved by all major classification societies. Named customers include Kongsberg Defence & Aerospace, Kongsberg Discovery, Autronica, GE Healthcare, Wärtsilä, Stingray Marine Solutions, Eelume, 4Subsea, Shearwater GeoServices, Trisense, Statens vegvesen, and Traftec, reflecting diversified exposure across regulated end markets.

In 2024 Fosstech became a portfolio company of Bertel O. Steen Industri (BOSI), part of the Bertel O. Steen Group (a Norwegian conglomerate with approximately 3,000 employees and annual revenue exceeding NOK 20 billion). Founder Steven Foss transitioned to Business Development Manager in 2025 and Oddbjørn Bergem was appointed CEO. Fosstech is privately held with no disclosed funding rounds, IPO, or external venture-capital or private-equity ownership signals in the available record.
