Product overview
DeepL is a Cologne-based company that provides machine translation and AI writing tools. Its translation service covers over 30 languages and is widely considered more accurate and natural-sounding than competitors like Google Translate, particularly for European language pairs. The platform handles text, full documents (PDF, Word, PowerPoint), and since 2026 offers a Voice API for real-time speech transcription and translation. The company grew out of Linguee, an online bilingual dictionary founded in 2009. DeepL Translator launched in August 2017, trained using a proprietary neural network architecture running on a supercomputer operated in Iceland with hydroelectric power. The company has raised over $400 million in total, including a $300 million Series C led by Index Ventures in May 2024 at a $2 billion valuation. Investors also include ICONIQ Growth, IVP, Bessemer, and Atomico. DeepL serves over 200,000 business customers, with a large proportion of the Fortune 500. Enterprise clients include Zendesk, Deutsche Bahn, Nikkei, and Coursera. The company employs around 1,500 people.
