STT

What STT does

STT (Société de Traduction Technique) is a French language services company founded in 1988 and headquartered in Thierville-sur-Meuse, France. Operating as an SAS (Société par Actions Simplifiée) with 150,000 euros of capital, the firm delivers translation, interpreting, and related linguistic services to a client base spanning SMEs, multinational corporations, local authorities, and European institutions across France and Europe. Its stated production capacity is approximately 10 million words per year across more than 180 language pairs, coordinated through a network of more than 300 vetted freelance translators and interpreters with whom STT maintains long-standing relationships.

The service portfolio is organized around four core offerings — translation and revision, interpreting (simultaneous, consecutive, liaison), Computer-Assisted Translation (CAT) with translation memory, and terminology management — augmented by added-value services such as DTP, certified legal translation, localization, CAD adaptation, copywriting, and transcription. Technology is conventional but purpose-built: STT operates proprietary in-house project management software that automates contractor selection, a terminology management system with a ten-level client-preference taxonomy, and a secure IT stack (own servers, Microsoft partner status, BitLocker-encrypted off-site backups, Active Directory-isolated secure FTP, proxy-mediated data exchange). The firm holds ISO 9001:2015 certification from TÜVRheinland (most recent audit 30/01/2025) for translation and linguistic engineering, and states compliance with RGPD/GDPR.

Commercial operations are sales-led and direct: pricing is quote-based, calculated per project according to service type, language pair, volume, technical complexity, and format, billed per source/target word, per hour, or at an inclusive fixed fee. Customer acquisition is driven by the multilingual corporate website (French, English, German), telephone, email, and fax, with free quotations typically returned within a few hours. For large or urgent engagements STT requires 30% payment at order and 70% during execution. Distribution is regional, with no disclosed expansion offices, subsidiaries, or digital channels beyond the website.
