About us
Let us build a bridge

between your company and the world


“Few things are as timeless as written text. The exact words and their precise meaning make it unique and singular. For Zesauro, every text is a well thought-out creative process that must be treated with care and respect, so as to cross language barriers without compromising its original value. This, combined with the careful revision and editing of all projects, ensures that we can meet our clients’ high standards.”

—María Zurita


Zesauro’s main challenge is to render accurately and meticulously every single text that we are given, in the client’s chosen language.

We painstakingly seek the precise meaning of every written or spoken word, so as to create in the mind of the reader or listener the unique image that the author wishes to convey.

And all of this rests on the cornerstones of our services: QUALITY and CONFIDENTIALITY.

As proof of our commitment to quality, we have been certified in UNE-EN ISO 9001:2015 and UNE-EN ISO 17100:2015 since 2008. The ISO 17100 standard applies specifically to translation services, and requires the use of fully qualified translators, revisors and proofreaders, with a special emphasis on the revision of the text by a second professional, who must be as qualified and experienced as the first translator.
