Grant Thornton Baltic OÜ

What Grant Thornton Baltic OÜ does

Grant Thornton Baltic OÜ is a Tallinn-headquartered professional services firm and member of the Grant Thornton International network, operating across Estonia, Latvia, and Lithuania since 1992. The firm delivers a broad, integrated service portfolio spanning audit and assurance, accounting and payroll, tax advisory, legal advisory, financial advisory (including due diligence, valuation, and restructuring), risk management and internal audit, information security, sustainability/ESG, HR and recruitment, and digital services, with additional specialized offerings for crypto-asset service providers and fintech. It serves a heterogeneous client base that includes large listed corporations (e.g., Eesti Energia, Ekspress Grupp, Baltika, Hepsor, Airobot), mid-market industrials (BLRT, Graanul Invest), and SMEs, with six offices across Tallinn, Tartu, Riga, Vilnius, Kaunas, and Klaipeda, 23 partners, and 350+ employees.

The firm operates as a partner-led professional services business, generating revenue through direct client engagements priced per project or scope rather than via publicly disclosed fee schedules. Go-to-market is sales-led and uses a multi-channel mix including content marketing, email newsletters, seminars ("Hommik nõustajaga"), events, and media appearances (e.g., Äripäev Radio's "Kasvukursil"). In 2025 the firm launched "Virtuaalsed tehisaru assistendid" — a suite of AI-powered virtual assistants including a work contract checking assistant — built by its own specialists and offered free of charge, representing a digitally-enabled front-end service layer. The firm holds ISO 27001:2022 certification for its information security management system and is owned and controlled by its Baltic partners under the global Grant Thornton brand.
