What Villari does
Villari B.V. is a Delft-based deep-tech company that builds permanently installed wireless sensors for real-time crack detection on steel structures, targeting aging critical infrastructure in ports, steel manufacturing, bridges, and offshore/wind assets. The technology uses magnetic field-based sensing combined with a proprietary, DNV-RP-A203-certified crack detection algorithm to identify small fatigue cracks at an early stage, including subsurface defects, without requiring surface preparation or operational downtime.
The product is sold as integrated hardware-plus-software: sensors are deployed on customer assets and paired with continuous monitoring services that deliver crack-growth data and predictive maintenance insights. Villari pursues enterprise customers through direct field sales supplemented by a structured partner program and a global distribution agreement with MISTRAS Group announced in October 2025. Named customers include Hutchison Ports, ArcelorMittal, TATA Steel, and Port of Antwerp.
The company is a spin-off from TU Delft, founded in 2019 and operating with 11–50 employees. It has raised approximately €2.85M plus a ~$4.16M round in January 2025 from FORWARD.one, InnovationQuarter, UNIIQ, and Delft Enterprises. Pricing is custom and quote-based, structured around multi-year contracts combining sensor deployment with recurring monitoring services.
