Where conventional material and component inspection reaches its limits, our technology only begins. voidsy develops systems for the non-destructive inspection of safety-critical elements based on active thermography. Apart from measurement, we deeply care about generating actionable information because the true value of the inspection process emerges through intelligent analysis of the data.
Our systems are built on years of research and engineered specifically for industrial requirements. Through the sophisticated interaction of our hardware and software, we have created an ecosystem that facilitates, for the first time, highly precise results in active thermography. In doing so, we provide a comprehensive solution:
Before founding voidsy together in 2022, Dr. Holger Plasser, Dr. Günther Mayr, Dr. Gregor Thummerer, and DI Gernot Mayr conducted research and worked in the field of non-destructive material and component testing at a Josef Ressel Center at the University of Applied Sciences Upper Austria. Founding the company was the natural next step in transforming these research results into market-ready industrial systems.
Today, voidsy is backed by an interdisciplinary team with expertise in:
This expertise is further complemented by:

voidsy gmbh | Magazinstraße 18, 4600 Wels, AUSTRIA | [email protected] | Company registration: FN 587365 y | Managing Director: Dr. Holger Plasser

Holger Plasser combines many years of entrepreneurial experience with deep expertise in physical engineering and measurement technology. After working as a process engineer in the steel industry and in industrial automation, he founded an IT company and later led complex industrial projects.
Today, his focus is on strategy, business development and bringing voidsy technology into industrial applications. He is a certified thermography expert (Level III, Austrian Society for Non-Destructive Testing) and an active member of the corresponding technical committee.

Günther Mayr is an expert in active thermography and non-destructive testing with many years of experience in industrial research. He established the Thermography & NDT research group at the University of Applied Sciences Upper Austria and led numerous collaborative industrial research projects with a total volume exceeding €8 million.
At voidsy, he focuses on developing practical inspection methods and transferring them into industrial applications. In addition, he serves as a thermography expert and an active member of varios national and international technical and standardization committees.

Gregor Thummerer combines a strong mechanical engineering background with extensive hands-on experience across the entire industrial value chain. His expertise ranges, among others, from manufacturing and mechanical design to the development of technical systems. A particular focus of his work lies in the practical development and optimization of 3D defect reconstruction algorithms for industrial applications.
At voidsy, he contributes his deep understanding of active thermography and ensures that complex technological concepts are translated into robust deployable solutions.

Gernot Mayr brings extensive experience in mechatronics, mechanical engineering and sensor development. He has worked as a design engineer as well as a development and project engineer, combining industrial hands-on expertise with deep knowledge of automation and intelligent sensor systems. For several years, he has also been active in applied research, focusing on the advancement of thermographic inspection methods.
His core expertise at voidsy, therefore, lies in the development and integration of sensor systems and in connecting software and hardware within industrial applications.
