Villari B.V.

Villari B.V. is a fast-growing Dutch start-up that originated as a spin-off from the Techincal University of Delft. Villari is dedicated to extending the structural lifetime of steel structures in ports, infrastructure and the steel industry through its crack detection technology, which is certified by DNV.
Villari's permanently installed wireless sensors monitor fatigue crack initiation and growth in critical locations using local variations in the magnetic field. The raw data is transmitted wirelessly using LoRa, stored in a secured environment, analysed and regularly reported to customers via a dedicated online dashboard.
The Villari monitoring system allows structure owners to track fatigue crack growth in the critical areas of their assets on a highly frequent basis. Compared to traditional methods, the company offers continuous and accurate inspection, carefree installation, competitive pricing and certified technology.
Villari's innovative solution has earned the trust of esteemed customers such as Tata Steel Europe and a Directorate-General of the Ministry of Infrastructure and Water Management of the Netherlands (Rijkswaterstaat), as well as ProRail, a Dutch government organisation responsible for the maintenance and extension of the national railway network infrastructure.
As of 2024, 1300 sensor systems were installed across Europe, for example in the Netherlands, Belgium, Germany and the UK, with some of them monitoring the assets for more than two years, ensuring the safety and longevity of critical steel structures worldwide.
