Linguee pioneered the online bilingual concordance. The concept behind it was conceived in the fall of 2007 by former
Google employee Gereon Frahling and developed in the following year along with Leonard Fink. The business idea was recognized in 2008 with the main prize of a competition founded by the German
Federal Ministry of Economics and Technology. In April 2009, the web service was made available to the public. Linguee is operated by DeepL SE (formerly DeepL GmbH and Linguee GmbH) based in
Cologne. In 2017, a team of Linguee employees around Jarosław Kutyłowski developed and launched the
DeepL Translator, a freely-available translation service capable of translating to and from seven major European languages. Since then, DeepL was gradually expanded to offer 24 languages and 552 language pairs. With increasing focus on Kutyłowski's product (DeepL), Frahling decided in 2019 to leave the company. Kutyłowski restructured the company into the
Societas Europaea DeepL SE in 2021. == See also ==
