About us

Machine Medicine Technologies (MMT) uses computer vision and computational statistics to enhance the neurological assessment of patients. Our first product, KELVIN, allows assessments of motor dysfunction conditions to be performed, recorded and used both faster and better than has ever previously been possible. KELVIN is already in use at clinical sites across several countries to support routine patient care and clinical trials. MMT aims to build the platform into a generalized tool for patient selection, surgical planning and device programming for machine brain interfacing, a revolutionary therapeutic innovation.


A fast-moving startup, with an energetic and dynamic team, looking to disrupt the MedTech industry with AI. Our employees are encouraged to take on the sort of career development opportunities that cannot be found at larger, more established, companies. We are in the highly regulated medical device industry, so our engineering team has to have an even greater focus on quality, usability and versatility. We also like to blow off steam, whether that’s playing a few rounds of table tennis in the office, or arranging an online gaming session.
