ABOUT US
HISTORY
TESI was born in the city of Gandia in 1984, coinciding with the worldwide emergence of “microcomputing” and the beginning of major technological changes applied to market and opinion research.
With over 40 years of experience in data processing services and since the early 1990s, innovating in the development of tools for market research, TESI is dedicated to providing advanced technological solutions.
We specialize in offering state-of-the-art systems that empower our clients in their data collection processes for research and information analysis, ensuring they have the necessary resources to make informed and strategic decisions.
The year 2024 will be framed in TESI’s annals, as four decades earlier, we embarked on a project driven by the enthusiasm to achieve everything we set out to do.
From when our company started by marketing the BARBRO system to the present day, where we are present in more than 15 countries and offer the most advanced services to obtain the largest volume of information in shorter periods of time, four decades of innovation, cutting-edge technology, continuous improvement and constant evolution have passed.
During this time, we have launched new intuitive and easy-to-use tools, several integrated and modular systems, and with service always available to support the client in data processing.
And all for our clients, who are increasingly demanding and with the highest expectations placed on us. Because excellence is born from demand. Personalized attention and closeness with clients and users are the main milestones to fulfill our company’s mission and vision. Our challenge remains the commitment to do things in the best possible way. Many thanks to our clients for making us grow with them, for always accompanying us, and in the years to come.
Many thanks also to our team. A highly qualified human and technological group, which is constantly up-to-date so that our systems and services respond to the greatest information demanded. Because without it we would not be what we are.
