MENDI

Mendi is a Swedish company behind a consumer brain-training system, based at Östermalmsgatan 26A in Stockholm and registered as Mendi Innovation AB. Its product is a headset that uses functional near-infrared spectroscopy to read blood flow and oxygenation in the prefrontal cortex, feeding a ten-minute daily game that trains users to activate and sustain focus.

The company presents the device as a wellness tool rather than a medical one, and reports more than 72,000 users and 2.5 million training sessions. The app supports multiple profiles, connects over Bluetooth to iOS and Android and ships without a subscription; Mendi states that its sensor was validated against laboratory fNIRS equipment by researchers at Stockholm University, and that the product builds on four decades of peer-reviewed neurofeedback research.
