VTplus is the market-leading provider of highly integrated Virtual Reality (VR) simulation systems for the treatment of mental and behavioural disorders with confrontation and behavioural exercises in VR, as well as for conducting scientific studies with virtual reality.

VTplus was founded in 2010 as a spin-off of the department of Psychology at the University of Würzburg. Our interdisciplinary team consists of psychologists, psychotherapists, computer scientists, graphic and media designers. VTplus has many years of experience in the application and evaluation of virtual reality as well as system development.

VTplus provides VR-Therapy turnkey solutions (EEC medical devices). Our VR-Therapy systems provide exposure and behavioural exercises for anxiety, addiction, as well as social skills- and stress management training.

The range of services includes design and consulting for VR systems, body sensors, simulation software and interactive VR content, as well as project management and project realization.


VTplus sees VR as a great method to advance therapy – aiming not only to provide new treatment possibilities, but to make the work of the therapists more efficient with the help of technology. We strive for scientifically sound solutions for the digitalization in medicine and healthcare. For this purpose, we cooperate with renowned scientific and industrial partners.

VTplus develops psychotherapeutic applications as well as medical- and rehabilitation applications of neurological disorders like stroke therapy and the treatment of chronic pain.
