Mendi develops a portable neurofeedback system designed to help users train activity in the prefrontal cortex. The company’s core product combines a wearable headband based on functional near-infrared spectroscopy (fNIRS) with a companion mobile app, allowing users to monitor changes in cerebral oxygenation and receive real-time feedback during guided training sessions.

Unlike many consumer neurotech products that rely on EEG, Mendi’s approach uses fNIRS to focus on localized hemodynamic signals in the frontal lobe. By measuring relative changes in oxygenated and deoxygenated hemoglobin, the system provides a proxy for cognitive load and prefrontal engagement. This signal is used to drive a gamified neurofeedback experience, encouraging users to develop greater control over attention and mental effort through repeated practice.

Mendi positions its technology at the intersection of wellness and validated neuroscience. The company has collaborated with academic groups to assess the reliability of its measurements and has emphasized grounding product claims in peer-reviewed research and established cognitive metrics. Its intended use cases include improving focus, supporting stress regulation, and enhancing overall mental well-being through regular, at-home training rather than occasional clinical assessments.
