Physiological truth for mental health systems.
The infrastructure layer between human physiology and intelligent systems.
The Problem
Mental health tools rely on self-report in moments of highest distortion.
Digital mental health platforms ask users to describe their emotional state precisely when that state is most likely to distort self-perception. Stress, anxiety, and acute episodes systematically undermine the accuracy of self-reported data.
Clinical Detection
Replacing self-report with physiological ground truth.
Nefesh delivers continuous, real-time physiological state data — derived from heart rate variability, stress scoring, and baseline calibration — to mental health platforms. Interventions can be triggered, timed, and adapted based on what the body signals, not what the user reports.
Ground Truth
What people say vs. what bodies show.
Self-report accuracy collapses exactly when it matters most. Nefesh reads the body instead.
"I'm doing okay, just a bit tired."
