Mendi

Mendi provides wearable brain training devices that use functional Near-Infrared Spectroscopy (fNIRS) technology to measure and train brain activity in real time. The smart headset reads blood flow and oxygenation in the prefrontal cortex to track attention, decision-making, and executive function, converting brain signals into a live training game that creates a feedback loop teaching the brain to focus on command. Based on decades of fNIRS research used in neuroscience labs, Mendi's technology builds neuroplasticity through repeated 10-minute daily training sessions. After eight weeks of use, aggregated data shows 42% improvement in sustained focus, 31% reduction in perceived stress, and 51% better general wellbeing. The device is used by over 72,000 users who have completed 2.5 million training sessions, with no subscription fees required. Founded in 2017 and headquartered in Stockholm, Sweden, Mendi has raised approximately $8.2 million in Seed funding from investors including EIC Fund, Sting, Almi Invest, and First Venture.
