Our way to success

SII Concatel already has more than 20 years of experience in the sector. Today, in our youth and with the whole future ahead of us, we hope to be able to face new challenges and opportunities.

Since 1998, the evolution of SII Concatel has been marked by a key concept: growth. Ours, and that of the more than 500 organizations we have helped on their way to transformation and innovation. In 1998, we went to the market with the first version of our Portal Framework content manager and the same founding values ​​that still govern us today: proximity, innovation, and commitment to the quality of our products and services. The respect for these values ​​has allowed us to expand our influence in the market to become a global provider of IT services and solutions.
