Mazanti-Andersen

What Mazanti-Andersen does

Mazanti-Andersen is a Danish law firm founded in 1853, headquartered in Copenhagen with an additional office in Odense. The firm operates as an Advokatpartnerselskab (limited liability partnership) with 32 equity partners, 9 associate partners, and between 101 and 250 total employees, including associates and support staff. It has no external investors and is entirely partner-owned.

The firm serves Danish and international businesses across a broad practice mix that spans M&A, venture capital, real estate, insolvency and restructuring, dispute resolution, corporate/commercial law, employment, IP, gaming, shipping, and competition law. Its deal pipeline includes recently visible mandates such as the Hovedstadens Bygningsentreprise matter and the Aety acquisition, and it has contributed to the Legal 500 M&A Country Comparative Guide, signaling sustained engagement in mid-market Danish transactional work. Beyond traditional advisory, the firm has begun layering in technology-enabled services, including the Nordic Whistle whistleblower platform hosted on Microsoft Azure, and uses AI tools in controlled environments for case management.

Commercially, the firm operates a standard professional-services model, generating revenue primarily through hourly and project-based fees billed to corporate clients, supplemented where applicable by recurring compliance subscriptions tied to its technology products. Pricing is anchored to partner and associate time, with client mix skewed toward Danish enterprises and select international counterparties; client identities are largely undisclosed publicly, with only a handful of named engagements visible. The firm's positioning as a long-established, partner-led Danish firm supports its appeal to clients seeking continuity and senior-level attention on complex regulated and transactional matters.
