Tõlkebüroo Interlex

What Tõlkebüroo Interlex does

Tõlkebüroo Interlex is a privately held Estonian language services company founded in 1997 in Tallinn, operating as Interlex OÜ. It provides written translation, editing, sworn/official translation, machine translation post-editing (MTPE), interpreting, and audiovisual/subtitling services across 50+ language pairs to enterprise clients in legal, technical, medical, financial, marketing, and government segments. The company holds ISO 17100 (translation processes) and is the first in Estonia to hold ISO 18587:2017 (machine translation post-editing). It reports translating more than 40 million words annually for a base of 2,500+ customers, making it one of the Top 3–4 translation agencies in Estonia.

The core product portfolio is built around three layers. First, services: human translation (ISO 17100-compliant two-linguist workflow), AI-validated translation (MTPE, ISO 18587-compliant), sworn translation via the absorbed Dussan OÜ brand, on-site and remote interpreting, and end-to-end subtitling that combines speech recognition with automatic translation. Second, technology platforms: an off-the-shelf Interlex Translation Platform (with translation memory, termbase, and machine-translation editing), and a custom-deployed platform hosted on the client's own infrastructure with API integration for automated order management. Third, distribution: a direct-sales model with a website quote-request funnel and one-hour response SLA; a one-hour-response client portal at interlex.s.xtrf.eu; and a self-serve, minute-based mobile interpreting app delivered through a January 2026 joint venture with Finnish partner Youpret (Youpret Baltic OÜ). A 300-strong network of freelance translators and editors is coordinated by an internal project management layer.

The business model is largely services-led with growing platform/recurring components. Translation services price per word across three tiers (AI-validated pay-as-you-go, classic human translation, corporate/enterprise with dedicated teams and annual contracts); interpreting is minute-based via Youpret; subtitling and sworn translations are project-priced; and the Interlex Translation Platform carries subscription elements with API integration. Go-to-market combines B2B sales-led engagement with industry-event-driven brand building (Nordic Business Forum, GALA, tekom, EULOGIA). Growth has been delivered through a combination of organic expansion and roll-up M&A: the 2019 acquisition of Tartu-based Grata (technical/medical), the 2017 minority stake in Estonian CAT-tool start-up Skuuper, the 2024 merger with Dussan OÜ (sworn translations), and the 2026 Youpret JV for remote interpreting.
