T&T Consulting is a digital services company (ESN) that provides engineers to work on-site for its clients. The company has grown to as many as 360 employees, with only about twenty based at its headquarters in Sèvres, just a short distance from Boulogne, where the largest concentration of ESNs in France is located (Alten, Altran, etc.).
T&T Consulting’s client base initially consisted mainly of mobile network operators (SFR, Orange, Bouygues) and telecom equipment manufacturers (Ericsson, Nokia). Since then, it has diversified into related fields (private networks, ultra-high-speed broadband, cybersecurity, big data, IoT, etc.) and adjacent industries (transportation, energy), while remaining a key player in telecom consulting.
The company enjoys strong brand recognition, resulting in a high level of repeat business. In addition, it is increasingly involved in business consortiums, enabling it to be shortlisted for major multi-year tenders.
