The science of sleep, unlocked

Clinical-grade sleep, beyond the hospital.

Making medical-grade sleep diagnostics accessible to every patient, every athlete, everyone, everywhere.

The gap

Sleep today is measured either
too crudely or too rarely.

Consumer wearables are everywhere, but their staging is approximate and they lack data to assess sleep disorders — not something a clinician can diagnose or treat from.

Polysomnography is the reference standard, yet it needs a lab, a technician, and a tangle of electrodes — a single night, rarely repeated.

Undae closes the gap: expert insight, at home, over many nights. Ideal for athletes, wellness and home clinical-monitoring.

Environment

Undae brings sleep clinical evaluation where natural sleep takes place. Undae measures sleep without ever touching the sleeper. A thin, contactless mat records cardiac, respiratory, movement and sleep macro- and micro-structure through the night — no electrodes, no technicians required.

Longitudinal

Stability

Recording over several nights, to get a more stable characterization of the sleep disorders' severity, especially in sleep apnea, where night-to-night variability is high.

Automated

Scoring

Our algorithm reconstructs the full hypnogram — stages, latency, fragmentation — and sleep clinical events — apneas, arousals, periodic limb movements.

Evolutive

Learning

The model keeps training on new nights, so accuracy rises over time rather than standing still.

Agreement with polysomnography

Undae's automated scoring was benchmarked directly against clinical PSG — and it keeps climbing, as our continuously-learning algorithm trains on every new night of data.

“The lack of adequate tools to assess sleep in insomnia makes phenotyping — and choosing the right treatment — difficult. Undae's approach would mean better phenotyping and real follow-up of treatment efficacy.”

“A device that evaluates sleep at home over several nights would be highly valuable — for my clinical practice and my research alike. I strongly support these alternatives to clinical polysomnography.”

Prof. Dr. Med. Francesca SiclariNetherlands Institute for Neuroscience, Amsterdam

“Used non-invasively over many nights at home, this lets me propose the right solution faster, improve compliance, and reduce follow-up visits — time I can use to see more patients.”
