Our History

Founded in 2011

Thessaloniki Software Solutions S.A. (THESS) was founded in 2011 as a small company with the mission of using information and communication technology (ICT) for the improvement of the quality of life. To this direction THESS focuses on the development and marketing of innovative software and hardware solutions for biomedical, telecommunication and scientific applications. However, it is also ready to address the ICT needs of customers with special requirements about web services and mobile terminal applications.

Furthermore, the company is specialized in services in the field of computational life sciences with vast experience in numerical simulations for modeling physiological processes, mainly bio-heat transfer. The creation of numerical (digital) models for computer calculations is another business area of THESS.

Strong Scientific Background with Experience

The staff of THESS has a strong scientific background in the area of computational and applied electromagnetics, especially in the interaction of human tissues with radiofrequency radiation either for medical or for safety and compatibility (EMC/EMI) purposes. Its personnel has been involved in a number of projects at a national and European level ranging from the evaluation of human exposure to non-ionizing electromagnetic radiation to the quality assessment measurements of wireless and optical fiber networks.

THESS is your ideal partner for spearheading technological solutions and completing your mission!
