The Company

The company specializes in the development of bespoke applications-that is, specialized software tailored to the specific needs and specifications of each client or project-as well as offering comprehensive long-term support services (operational, technical/user support, and development). 

The company invests in developing its own solutions. The main platforms are RG and IoT. 

The expertise and tools used for application development are based on, or consist entirely of, open-source technologies.

More information and Demo 

We specialise in research and innovation in telemetry networks with real-time monitoring and advanced analysis workflows based on data mining and machine learning.

In this way, we offer the dissemination of end-to-end services, starting from the sensor and reaching the user interface. We focus on converting input information into smart and decisive data, with spatial and temporal annotation, ready to be used and visualised.

The services we provide cover the entire data lifecycle to facilitate smart decision-making and support a wide range of strategic and operational directions.
