Noxon is a deep-tech startup founded in 2022 with the vision to transform health on every skin - starting with your muscles. 30% of people worldwide struggle with muscle health challenges. To tackle this crisis, Noxon developed a non-invasive muscle-computer-interface: a medical wearable that translates muscle signals into code and conversely sends movement programs back into the muscle to trigger and correct movements. Guided by our purpose - moving what matters - we build technology that improves lives. We foster an environment where meaningful work and people who care come together to turn ideas into reality.
