Our history

More than 20 years of professional solutions

The history of HSS GROUP dates back to 1998, when Mr. Sebastian Acosta Diaz founded Gestoria Hispano-Suiza Acosta LLC in Zurich, initially focused solely on translation and interpreting services for Spanish-speaking residents in the country. However, the company soon became aware of the needs of Spanish-speaking residents and companies in terms of management and consultancy services and began to expand with a single objective: to create a group of companies through which to offer a comprehensive service, capable of assisting companies and professionals in all areas related to their activity.

In 2001, the group began to diversify with the foundation of HSS HIGH STANDARD SERVICES LLC (later HSS TREUHAND Ltd.), which was set up to offer business administration services and tax, legal and accounting advice to all types of companies, professionals, and individuals, as well as opening branches in other cantons in Switzerland.


Today, HSS GROUP is present in various parts of the country (Zürich, Schwyz, Zug…), and has experienced a great growth in size and number of employees. All this to be your reliable partner for all administrative, financial, and legal matters. Do you need more reasons?

A philosophy focused on the client and always adapting to the needs, context, and characteristics of each one. 100% personalised.
