21net was founded in 2001 and generated a turnover of €16m in 2017. The company has subsidiaries in France, Italy and India and employs 50 people.


It won a contract from French National Railways (SNCF) in 2016 together with Engie Ineo to equip SNCF’s entire TGV fleet of 2400 coaches with high-speed internet by the end of 2017. 21net has already worked with Alstom on the installation of Wi-Fi and infotainment on Italo-NTV high-speed train fleet in Italy.

“This new acquisition, one year after that of Nomad Digital, will reinforce Alstom’s digital offering and expertise,” says Mr Jean-François Beaudoin, Alstom’s senior vice-president for digital mobility. “The demand for seamless connectivity throughout passengers’ journey is today a must.”
