Boost your digital transformation with modern, compliant technologies

With Tessi, modernise your processes and control your risks!

With regulatory changes that encourage digital technologies and create new data security challenges, the management of your transactions and information flows is becoming increasingly critical.

It must rely on modern, scalable, compliant solutions.

As a digital transformation specialist, we produce software platforms that automate the management of your flows and communications to provide an environment in which digital trust can thrive.

Modular and widely deployed in either hosted mode or licensed mode, they meet your specific needs by modernising your processing in key areas: document management, payments, CRM and marketing automation, security and digital trust, and business management.

As a publisher, we continuously update our software.

Our solutions are certified to assure you and your clients that your exchanges maintain their legal value, and we are recognised as a trusted third-party operator.


"We believe in an autonomous technological vision, but one that is co-constructed with our customers. This strategy is embodied by men and women constantly in pursuit of value creation, to embed digital trust and new technologies in our solutions"

Thierry Caye Deputy Director Operations and Technologies
