Tactis, the French leader in digital territory organization
Tactis is an independent engineering and consulting group, founded in 1995 by Stéphane Lelux.
The group offers strategic consulting services and operations assistance. It is involved in a wide variety of missions in the following areas:
- High and ultra-high speed telecommunications (fixed and mobile),
- Innovative territories (“smart” urban or rural projects, data management, mobility, energy, durable development…)
- Economic development related to digital technology.
Our mission: to identify projects and support their implementation.
For the past ten years, our business has developed strongly in Europe and on the African continent.
Our group is wholly-owned by its management team, via the Innopolis holding. From its neutral position, it provides expertise to decision makers, from project startup through project implementation and follow-up.
The office carries out nearly 100 missions per year and obtains 50% of its revenue from the international sector, principally on the African continent and the Middle East. For the year 2017, the Tactis Group’s anticipated turn over is estimated at approximately €10 million gross with more than 70 collaborators.
The group
The Tactis Group has developed through the creation of two subsidiaries, Tactis Ingénierie and Tactis Innovation Services, in order to accelerate the development of activities that are complementary to the board’s missions.

Tactis Ingénierie was created in 2014 for:
- the operational support for the management and control of the construction of telecommunications networks
- the operations audit
- the service quality
Since 2015, Tactis Innovation Services supports:
- the services and usage component (services platforms, public management of the data…)
- the innovative public policies (Smart City, Smart territories…)
