Executive summary 

The main project of Exia Belgium, the Active Sideguard™, is an innovative blind spot accident avoidance device for heavy trucks, using electrostatic sensors technology for detecting cyclists and pedestrians. Bringing their expertise in automotive safety software and embedded software development, Tremend team members became partners with this ambitious startup and helped its founders turn its ideas and early prototypes into a fully functional product and bring it to market.

The client 

Exia Belgium is a technology spin-off initiative of the Vrije Universiteit Brussel, Department of Electronics and Informatics (ETRO), in collaboration with iMinds vzw Belgium.

Exia aims to be an independent R&D driven provider of blind spot accident avoidance sensor technology for for heavy goods vehicles (HGV), municipal vehicles, busses, coaches and other oversized vehicles. The company’s innovative electrostatic sensor solutions contribute significantly to the safety of vulnerable road users, optimizing vehicles operation costs while reducing the financial implications of maneuvering damage.

Business Challenge 

The challenge was to develop their product, The Active Sideguard™, from scratch, helping the startup turn its ambitious idea into a functional product and put it on the market.
