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.

Our company has become one of the most important in the sector thanks to our vast experience (30 years providing profitable multilingual solutions); our international scale, with a presence in 11 countries and global coverage; the implementation of strict quality 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 allowed us to apply state-of-the-art technology in the translation and interpreting sector and bring our clients innovative services to suit their needs.

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


With regard to our quality systems, SeproTec was one of the first translation companies to receive the certifications ISO 9001, UNE-EN ISO 17100 for translation services and ISO 14001 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 1,000 clients worldwide.
