Overview

CLS Communication was a Switzerland-based provider of translation, editing, writing, terminology, and related language services. Founded in 1997 as a spin-off from Swiss Bank Corporation and Zurich Financial Services, the company developed from an internal financial-sector translation operation into an international language-services business serving regulated and technically demanding industries. Its client base included organizations in financial services, life sciences, telecommunications, legal services, insurance, banking, and investment management. The company expanded partly by taking language teams and specialized capabilities in-house. In 2002 it absorbed translation teams associated with Swisscom, Sunrise, and Raiffeisen, while also establishing offices in London and New York. It subsequently acquired or integrated specialist businesses and language teams, including London-based Richard Gray Financial Translations in 2004 and Berlin-based 4-Text GmbH in 2013. Its international footprint grew to include locations in Europe, North America, and Asia, including Paris, Madrid, Copenhagen, Frankfurt, Singapore, Hong Kong, Shanghai, and Beijing. CLS also acquired Lexi-tech International in Canada and Scandinavian Translators in Denmark after the company received new investment from Zurmont Madison. CLS positioned itself as a specialist language partner rather than only a general-purpose translation vendor. Its offerings included multilingual translation, copywriting, editing, technical documentation, terminology management, corporate-dictionary development, and machine-translation tools. It had particular experience with annual reports, financial communications, and documents connected with the European UCITS regulatory framework. Industry research published in 2013 by Common Sense Advisory ranked CLS Communication as the eleventh-largest global language-services provider. The company became fully independent through a management buyout in 2003. In 2009, Swiss private-equity firm Zurmont Madison became its majority shareholder through a capital increase and partial purchase of existing shares. Under the long leadership of Group CEO Doris Albisser, CLS grew substantially in staff, geographic reach, and external language-partner capacity. By the early 2010s, the company reported more than 600 internal employees and a worldwide network of roughly 5,000 freelancers; later information described approximately 20 in-house translators in Switzerland and about 2,400 external partners, reflecting changes in the business and reporting period. Lionbridge Technologies acquired CLS Communication in January 2015. The transaction placed CLS within one of the world's larger language-services groups while initially preserving the CLS name and local operations. Leadership subsequently changed: Matthias Trümpy gave up the CEO role to Tom Spel in 2015, and Markus Hacker became General Manager for Central Europe in 2017. Pius Fellner assumed operational management of the Swiss Lionbridge and CLS businesses in September 2018. In November 2018, the CLS Communication name was retired in favor of Lionbridge Switzerland AG. The former CLS operation therefore continued as part of Lionbridge, although CLS Communication no longer operated as an independent brand.

History

CLS Communication was established in 1997 as a spin-off from Swiss Bank Corporation and Zurich Financial Services. Its original business was closely connected to the need for professional multilingual communication in banking and financial services. The company later broadened its client base and developed a more independent operating model. A major stage of expansion came in 2002, when CLS brought in translation teams associated with Swisscom, Sunrise, and the Swiss Raiffeisen banking group. The move expanded its telecommunications and banking expertise and supported the opening of offices in London and New York. In 2003, a management buyout made the company fully independent. CLS continued to grow through geographic expansion, acquisitions, and the incorporation of specialist language teams. It acquired Richard Gray Financial Translations in London in 2004, after which it added or developed operations in Paris and Madrid. Further offices were established in Copenhagen, Frankfurt, Singapore, Hong Kong, Shanghai, and Beijing. The company also took over language-services teams associated with Swiss Re, Lombard Odier, and Danske Bank. In 2009, Zurmont Madison became CLS's new majority shareholder through a capital increase and partial buyout. During this period, CLS acquired Canadian translation company Lexi-tech International, formerly owned by J.D. Irving, and Danish company Scandinavian Translators. In January 2013 it acquired 4-Text GmbH, a Berlin-based specialist in technical-documentation translation. 4-Text brought more than 60 permanent employees and approximately 200 freelance translators, strengthening CLS in technical and industrial content. Doris Albisser served as Group CEO for 16 years and oversaw the transformation of CLS from an internal bank translation operation into a major international language-services provider. She transferred operational leadership to long-time deputy Matthias Trümpy in August 2013 and became Vice-Chairwoman of the Board. At that point the company was described as having more than 600 internal employees and around 5,000 freelance language professionals worldwide. A 2013 Common Sense Advisory industry report placed CLS Communication eleventh among global language-services providers. Lionbridge Technologies acquired CLS Communication in January 2015. The company initially continued to operate under its established identity within the Lionbridge group. Matthias Trümpy handed the CEO position to Tom Spel in July 2015, while Markus Hacker became General Manager for Central Europe in July 2017. Pius Fellner assumed operational responsibility for the Swiss Lionbridge and CLS businesses on 1 September 2018. In November 2018 the CLS name was replaced by Lionbridge Switzerland AG. The business consequently became a Lionbridge operation rather than an independent CLS-branded company. CLS's services covered translation, editing, writing, terminology management, corporate-dictionary programs, machine translation, and technical documentation. Its specialist sectors included financial services, life sciences, telecommunications, legal services, insurance, banking, and investment management. It also handled annual reports and documents relating to the European UCITS regulatory framework. The company reported more than 900 clients in information relating to 2011. Later descriptions identified a smaller Swiss in-house translator base and a network of external partners, illustrating the importance of distributed freelance capacity in its operating model.
