LOGOS Legal Services

What LOGOS Legal Services does

LOGOS Legal Services (legal entity LOGOS slf.) is Iceland's oldest and largest full-service law firm, founded in 1907 by Sveinn Bjornsson, who later became Iceland's first president. Operating from a single headquarters at Efstaleiti 5 in Reykjavík following the October 2024 closure of its London office, the firm employs approximately 65 people, including over 50 lawyers organized across 22 practice areas spanning corporate/commercial law, banking and finance, mergers and acquisitions, dispute resolution, competition, tax, employment, data protection, EU/EEA law, energy, fisheries, aviation and maritime, real estate, sustainability, and private client services.

The firm operates a partnership-style ownership model (LOGOS slf., Icelandic Reg. No. 460100-2320) with no external institutional or PE/VC investment. Its go-to-market combines a sales-led motion built on professional referrals, multi-jurisdictional cross-border execution through its exclusive Icelandic membership in the Lex Mundi network (22,000+ lawyers across 125+ countries), and reputational credibility sustained by top-tier rankings in Chambers Global, The Legal 500 EMEA, and IFLR1000. Clients are primarily domestic and international corporates, including approximately 50% of Icelandic stock-exchange-listed companies, alongside pension funds and high-net-worth individuals.

Revenue is generated on a quote-based professional services fee model tied to matter complexity. Marquee recent mandates include the Icelandic government's ISK 90.5 billion (approximately USD 700 million) privatization offering of its remaining 45.2% stake in Íslandsbanki, an ISK 651 billion HFF bond settlement on behalf of 18 pension funds, and a Supreme Court victory for Arion Bank in a variable interest rate case. In June 2025, LOGOS expanded its service surface through a cooperation agreement with Syndis to provide integrated legal and cybersecurity advisory services targeting DORA compliance and cyberattack response preparation.
