What Kancelaria Ostrowski i Wspólnicy sp.k. does

Kancelaria Ostrowski i Wspólnicy sp.k. is a full-service Polish law firm headquartered in Toruń (Kujawsko-Pomorskie region), founded in 1998 and operating as a limited partnership (spółka komandytowa). It is organized around ten core practice areas: corporate and business law, tax law, labor and social insurance law, real estate, infrastructure and construction, transactional advisory (M&A, private equity, restructuring), court disputes and debt collection, Life Science, GDPR/AI compliance, and EU funds/state aid, plus a dedicated family foundation practice. With a team of 50+ legal professionals including managing partners and licensed tax and restructuring advisors, the firm has held the #1 ranking among law firms in Kujawsko-Pomorskie for 14 consecutive years per the Rzeczpospolita ranking, and maintains a secondary presence in the Tri-City (Gdańsk/Gdynia/Sopot) area.

The firm generates revenue through professional services engagements — billed hourly, per project, or via retainer — for a client base spanning SMEs, family-owned businesses, and large enterprises, with particular focus on the Kujawsko-Pomorskie region and selected national mandates. Distribution is direct via phone, email, and website contact channels, supported by a content-led marketing engine built around three specialized blogs (Laboratorium Prawa Pracy, Kraj Podatkowy, Law in Business) and ten dedicated practice microsites. In February 2024, the firm extended its service portfolio by opening a Restructuring Practice under affiliated entity Ostrowski Consulting, leveraging a new restructuring advisor license obtained by managing partner Paweł Cioban. The firm holds no patents, operates no proprietary technology platform, and is privately held by its managing partner group with no external parent or PE backing disclosed.
