What SIRIUS advokater does

SIRIUS advokater is a Danish law firm organized as an interessentskab (partnership) and headquartered in Copenhagen. Founded in 2006, the firm operates approximately 60 staff including partners, lawyers, attorney assistants, paralegals, and administrative personnel. It provides specialized legal advisory and litigation services across ten practice areas: employment and labor law, construction law, corporate law and M&A, public law, tax and duty law, insolvency, dispute resolution, procurement law, GDPR/data protection, and intellectual property. The firm serves a balanced client base of private businesses, public authorities and government entities, as well as foundations and associations.

The firm delivers professional services on a time-based billing model, with publicly disclosed hourly rates ranging from DKK 700 (paralegals) to DKK 4,350 (partners), excluding VAT. It issues invoices upon task completion or periodically for larger ongoing matters, with 14-day payment terms. Initial client engagement follows a documented process including conflict checks, identity/AML compliance (via Visma Creditro), and a written engagement letter covering scope, personnel, fee estimates, and terms. The firm has no proprietary technology platform; its core assets are its people, legal expertise, and external recognition (Legal500, Chambers Europe).

The firm's go-to-market is relationship-based enterprise field sales: client acquisition is driven by professional reputation, legal rankings (Legal500, Chambers), professional association participation (Advokatsamfundet, Danske Advokater), hosting of educational events (morning meetings, go-home meetings), newsletters, and LinkedIn thought leadership. The firm has invested in seasonal lateral hiring of senior partners from top Danish firms (Plesner, Kammeradvokaten/Poul Schmith, Elmer, DLA Piper) to build specialized practices, particularly in insolvency, construction, and procurement law.
