ZELENKA

What ZELENKA does

ZELENKA is a privately-held, family-owned language services provider (LSP) headquartered in Zlín, Czech Republic, founded in 1990 by Zbyněk Zelenka. The company delivers professional translation, localization, desktop publishing (DTP), machine translation with human post-editing, subtitling and voiceover, patent translation, and language consultancy across 120+ languages and 220+ industries, completing more than 300,000 projects over its 35+ year history. Underlying technology centers on a curated global network of 9,500+ freelance translators, interpreters, and graphic designers, supported by established computer-assisted translation (CAT) tools — primarily SDL Trados Studio, SDL Studio GroupShare, SDL MultiTerm, memoQ, and XBench — along with translation memory systems, terminology management, and AI-based neural machine translation followed by human post-editing. ZELENKA holds ISO 9001 and ISO 17100 certifications (audited by TÜV Nord) and is ranked by CSA Research as the 4th largest translation agency in Eastern Europe as of 2024.

The business model is professional services, quote-based, with three published quality tiers (BASIC, STANDARD, PREMIUM) priced on a pay-as-you-go basis; specific price points are not publicly disclosed. Revenue is generated across core translation services, machine translation post-editing, localization, DTP, multimedia production, and consultancy. Go-to-market is direct-to-enterprise via the company website (with localized versions for Czech, German, and Slovak markets), phone and email sales, dedicated account managers, and participation in industry events such as tekom, ELIA, and the Japan Translation Federation Annual Conference. Primary customer segments are engineering, automotive, IT, healthcare, legal, and marketing/creative, with named enterprise clients including Siemens, Continental, ASUS, BMW, Lenovo, ABB, Alstom, Emerson, and Porsche — several of whom have retained ZELENKA for over a decade. The company has no disclosed funding rounds, operates without a parent company, and is governed by three managing directors (Zbyněk Zelenka, Iva Vedrova, and Ivo Vedra).
