What Sorainen does
Sorainen is a privately-held, full-service international law firm headquartered in Tallinn, Estonia, operating across the Baltic states through separate legal entities in Estonia (Advokaadibüroo Sorainen OÜ), Latvia (Sorainen ZAB SIA), and Lithuania (Advokatų profesinė bendrija Sorainen). Founded in 1995 and led by Managing Partner Eva Berlaus, the firm employs more than 300 lawyers organised around an integrated cross-border Baltic team that delivers legal and tax advisory across 16+ practice areas — including M&A, banking and finance, capital markets, dispute resolution, ESG, data protection, real estate, intellectual property, public procurement, employment, competition, and tax — and sector-specific verticals spanning defence, energy, life sciences and healthcare, TMT, and startups.
The firm's revenue model is professional services time-based billing, charging in units of 1/10 of an hour (6-minute increments), supplemented by a 2% administrative fee on total legal fees and late-payment interest provisions; rates may be increased for short-notice or urgent work. Its go-to-market is sales-led and direct, with client engagement through the three Baltic offices targeting enterprise and mid-market companies. Marketing channels combine subscription legal newsletters, sector events (e.g., Baltic M&A and Private Equity Forum), a content-driven newsroom, and earned media through industry awards including IFLR and Chambers Europe.
The firm has no external institutional investor or parent company and operates as a partnership under founder/partner ownership. Recognised logos span large enterprises (Salling Group, Ignitis Group, Mantinga Group, Viking Window), financial institutions (Multitude Bank, SEB Latvia), government bodies (City of Tallinn), and growth-stage companies (Oxipit, Gearbox Biosciences, Xtend). Key advisory mandates include the EUR 1.3 billion Salling Group acquisition of Rimi Baltic — the largest Baltic transaction of the decade — and EUR 318 million financing for the largest Baltic wind farm.
