About

About Calyo

Calyo is a Bristol sensing company founded around research in three-dimensional airborne ultrasound. Instead of treating ultrasound as a set of short-range parking points, its hardware forms spatial depth information that can be processed at the edge and fused with cameras, lidar or radar.

The company packages the technology through PULSE and SENSUS sensor systems and the PxAI processing stack. Its DRIVEN BY SOUND+ programme is intended to move the stack through vehicle integration and on-road validation at TRL 6–7, targeting the adverse-weather and close-range blind spots that can constrain optical perception systems.
