Advokatfirmaet Grette

What Advokatfirmaet Grette does

Arntzen Grette (legal name Advokatfirmaet Arntzen Grette, previously known as Grette) is a full-service Norwegian commercial law firm headquartered in Oslo, operating from four offices across Norway — Oslo (Ruseløkkveien 30), Trondheim (Beddingen 16), Stavanger (Kongsgårdbakken 1, with oil and gas sector focus), and Mo i Rana (Søndre gate 3). The firm employs 245 staff, including 185 lawyers and legal professionals, and serves Norway's leading companies across practice areas spanning corporate/M&A, dispute resolution, real estate, employment, sustainability/ESG, construction, and regulatory compliance. Its service offering is delivered through partner-led relationships backed by team-based execution, with no proprietary technology platform — the product is legal advisory itself rather than software or tooling.

The firm's revenue model is professional services: time-based billing for ongoing matters and project-based fees for discrete transactions such as M&A, litigation, and real estate deals. Pricing is quote-based and not publicly disclosed. Go-to-market is sales-led and relationship-driven, supported by a content marketing program (news/insights portal, newsletter, social media, and professional events) rather than digital distribution. Customer concentration sits in large Norwegian enterprises, with named mandates in 2026 spanning Supreme Court litigation for Entercard on BankID misuse, the Pandion Energy to Vår Energi divestiture on the Norwegian continental shelf, a ~30 billion NOK standing counsel role on the Nye Aker hospital build, the Swiss Life big-box retail property sale, and Havila Biogass's investment in Sømna Biogass. The firm's stated methodology ('løsningskraft') emphasizes understanding, clarifying, and executing on complex commercial decisions for major Norwegian corporates.
