IDUN Technologies AG, a 2017 spin-off of ETH Zurich, is fundamentally transforming the accessibility of brain data by moving neurotechnology from the clinic to the ear. The company has developed the IDUN Guardian, the world’s first consumer-grade in-ear EEG hearable that provides high-fidelity neural monitoring in a minimally obtrusive form-factor. With over EUR 1 million in investment and strategic collaborations with Qualcomm and Analog Devices, IDUN is positioning itself at the center of the "Internet of Humans". At CES 2026, the company unveiled its next-generation Guardian 4 device, which introduces a "Cognitive Readiness" score and live neurofeedback, signaling a transition from developer kits to a global consumer market for personalized neurotechnology.
