Thésée DataCenter is a French colocation hosting services provider (from a few computer racks to a complete building) independent from any telecom operators and cloud providers, based in the western Paris region.
Thésée DataCenter is also targeting cloud-computing service companies as customers who are particularly vigilant about their infrastructures efficiency, requesting a high level of availability and willing to remain independent from the major players.


Thésée DataCenter is a 100% French legal and controlled company. In addition to the historical shareholders - Christophe Bouniol and Eric Arbaretaz, two institutional companies - the Banque des Territoires and the IDEC GROUP - own each 24.9% of the company. A pool of French banks is also supporting the financing of this project.

"With Thésée DataCenter, the Banque des Territoires contributes to the economic attractiveness of the territory and helps provide local players with very high-quality equipment to serve the resilience and quality of their IT production. It thus acts as a wise third-party investor serving territories that are both more connected but also more sustainable ” declares Marianne LOURADOUR, Ile-de-France Regional Director of the Banque des Territoires.

The GROUPE IDEC is joining forces through its subsidiary GROUPE IDEC INVEST in this ambitious operation which is part of its development in favor of sustainable, connected and intelligent real estate.

"The virtuous approach of this new generation Data Center finds its full meaning in the responsible approach adopted by the IDEC GROUP to imagine, fit-out, develop, design and build work and living spaces fully integrated into their environment", explains Lionel MARY, Managing Director of GROUPE IDEC INVEST.
