Villari develops sensor technology that monitors and detects cracks in steel structures. The technology is based on accurate characterisation of locally present magnetic fields. Compared to conventional inspection and monitoring methods, Villari technology distinguishes itself by providing continuous permanent monitoring at low cost per monitored location.


Villari is a Dutch startup backed by Delft University of Technology, founded by Olivier Baas and Hugo Romer; both know each other through university. Olivier obtained significant knowledge in the workings of ferromagnetism through his thesis project at TNO and TU Delft. Hugo developed expertise in steel characterisation and fatigue problems during two years of working at Huisman Equipment.
