BIRETA Professional Translations

What BIRETA Professional Translations does

BIRETA Professional Translations is a Warsaw-based professional translation services agency founded in 2002 by Anna Kempińska and Joanna Wożaniakowska, operating as a Polish general partnership (Sp.J.). The company provides specialist written translations, simultaneous and consecutive interpreting, conference support, and classified document translation, with a 48-person in-house team coordinating a network of over 400 qualified freelance translators across European and Asian languages. Its core technology stack combines CAT (Computer-Assisted Translation) tools, translation memories, proprietary terminology databases, and a neural machine translation post-editing (MTPE) workflow delivered under ISO 18587; the firm holds triple ISO certification (ISO 17100, ISO 18587, ISO 27001) and ABW (Internal Security Agency) accreditation for classified document handling. BIRETA also owns three proprietary Polish-English specialized online glossaries — Offshore Wind, Hydrogen, and Nuclear — the first of their kind on the Polish market, with the Nuclear glossary containing 1,800+ verified terms developed in partnership with Nuclear.pl Foundation.

The company targets enterprise and mid-market B2B clients in six primary verticals: energy and renewables (offshore wind, nuclear, hydrogen, solar, conventional power), oil & gas and chemicals, defense and aviation, legal and financial, construction and transport, and IT and telecommunications. Named enterprise customers include Ørsted, Mitsubishi Power, Ocean Winds, Q Energy, Doosan, Savills, Meridiam, Multiconsult, and Gascontrol Polska, among others. BIRETA's go-to-market is sales-led and enterprise-field-sales oriented, delivered through direct outreach from Warsaw headquarters, project-based quoting via the company website, dedicated email channels for written and oral translation inquiries, and event-driven conference interpreting at major industry events. Marketing channels include a multilingual blog (Polish, English, German), LinkedIn, YouTube, conference sponsorships, and email newsletter with a translation price comparator as a lead magnet.

Revenue is generated through project-based fees for written translation (per word or per page), project-based fees for interpreting (per duration and language combination), subscription fees for the specialized online glossaries, and ancillary services including DTP, verification, localization, and document management. The company is entirely founder-owned, with no external investment or institutional capital identified, and operates from its headquarters at ul. Bronikowskiego 3 in Warsaw's Ursynów district.
