Who we are

Who we are

Nplus S.r.l. is a company that combines the enthusiasm, energy and innovative approach of a group of young entrepreneurs with the long experience of its work team. Add to that the strength of Giordano Riello International Group (GRIG) – one of the most important Italian industrial groups encompassing Aermec, Sierra, Fast, RPM and Elettrotest, with an annual turnover of more than 400 million Euros.

The Nplus offices and plant are located in Rovereto (Trento), in the Business Innovation Centre – BIC – for mechatronics and technologies. This is an industrially fertile area where R&D investments are subsidised and sustained by the local authorities, and there are also favourable terms for cooperation with the leading Italian universities and research centres.
