    Since 2012, we have been helping our clients in Business Development and achieving their goals in a market undergoing deep contraction and change. In line with corporate objectives, since 2020, we have finalized the acquisition by the French company Helpline, a European leader in IT support, User Experience, and digital transformation, in our shared path of geographical expansion, and we have become part of the international group under the everience brand. As part of the group, which employs over 5,000 people, we offer three main areas of business in Italy: Helpdesk Support Managed Services: Ongoing support from technicians, system administrators, and network experts for the client infrastructure in corporate and enterprise environments, aimed at reducing costs through digitalization and the implementation of nearshore multilingual solutions (300 agents in Timisoara, Romania). Break Fix Support and Technical Dispatch in Italy and Abroad: Through our technicians, partners, and suppliers, we support our clients in their global expansion projects, following them in different locations. We handle IMAC activities and distributed technological projects: we offer service management based on the ITIL framework across the entire process, 12 hours a day, 7 days a week. Technology Consulting: Thanks to our background and corporate experience, we provide SMEs with proven solutions, allowing them to focus valuable energy on revenue generation and cost reduction. We design and implement customized IT solutions while respecting client requests and objectives. For a no-obligation quote, we offer a free benchmark on the status of your technological services. Digitalizing your processes is a matter of how, not if. As soon as possible, not when. Why not be supported by experts?
