About Us

SeproTec Multilingual Solutions (SeproTec) is a leading company in the translation and interpreting sector. The company was born in 1989 with the aim of covering the demand for multilingual services brought on by an increasingly globalized society with growing language needs. The idea was to support our clients throughout their international expansion process and tailor their communication strategies to different languages and to each one of their markets.

Since then our company has become one of the foremost in the industry. Our success is attributable to our vast experience (more than 25 years providing effective multilingual solutions), our international scale (with a presence in 14 countries and global reach), the implementation of strict quality control systems, the wide array of services we offer (localization, translation, interpreting, multimedia, and so on) and our firm commitment to innovation and investment in R&D&I, which has spurred us to apply state-of-the-art technology to the translation and interpreting sector and bring our clients innovative services to meet their needs.

“SeproTec has become the go-to solution for supplying all of a company's multilingual needs.” Carlos León, Chairman of SeproTec.


As a testament to our quality systems, SeproTec was one of the first translation companies to receive the ISO 9001:2000 and UNE-EN ISO 15038-2006 certifications for translation services, and the UNE-EN ISO 14001:2004 certification for environmental management. All of our processes and workflows are externally audited and we receive favorable assessments year after year. These and many other factors have led SeproTec to be where it is today, with a portfolio of over 900 clients worldwide.
