Aro-Tek was born from the desire to create a competitive reality in the field of Information Technology services, with the aim of pursuing a differentiation of the traditional core business of Comas.

The idea of entering the IT services sector with Aro-Tek, aimed at the private sector, especially banks and insurance companies and softwares developement companies, as well as the public administration and pharmaceutical industry, immediately appealed to Comas’ corporate governance, also because on the basis of the important relationships established, the aim is to launch a commercial growth policy, also taking advantage of partnerships with important international and national brands.
