Sisem

What Sisem does

Sisem Srl is a privately held Italian specialist engineering company founded in 1999 and headquartered in Rende, Calabria. It provides professional engineering services to telecommunications operators, tower companies, network equipment vendors, and government institutions across Italy, organized around three practice areas: Telecommunications (electromagnetic compatibility analysis, network testing and optimization, interference hunting, RF consulting), Renewable Energy (full lifecycle project management for photovoltaic installations on building, ground, and urban sites), and Engineering (BIM design, Digital Twin creation with drone surveys, structural reinforcement design for antenna-bearing poles, on-field operations, site/DAS acquisition, and video surveillance system design).

The firm's technical stack centers on BIM-based design, drone-enabled digital twin creation (co-developed with partner Dron-e), proprietary interference hunting methodology registered under Italy's Patent Box regime, FEM structural analysis for telecom towers, and emerging Network Digital Twin research using AI models (co-funded PhD with UNICAL's DIMES department). Two co-funded doctoral programs with the University of Calabria (one on predictive maintenance of steel telecom structures, one on AI-driven network digital twins) signal investment in deeper technical IP.

Sisem operates an enterprise field-sales motion, selling quote-based project services directly to a roster of essentially every major Italian mobile operator (TIM, Vodafone, Iliad, Eolo), both major tower operators (InWIT, Cellnex), global equipment vendors (Ericsson, ZTE, Nokia), broadcasting infrastructure (RAI Way since 2025), and government bodies (Ministry of the Interior, ANAS-FS). Revenue is generated entirely through professional services fees with no disclosed pricing or recurring SaaS-style model, and the company remains confined to a single Italian headquarters with no disclosed subsidiaries, funding rounds, or international footprint.
