Built for the ICU
A purpose-built medical device that lives at the bedside — designed for the realities of critical care, not the lab.
Non-invasive neurodiagnostics
See the mind
See the mind
the body can't show.
Real time bedside brain activity — revealing awareness, intent, and recovery in patients who cannot move, speak, or respond.

patients every year cannot be accurately diagnosed
15–20%
of unresponsive patients show hidden, covert consciousness that standard bedside exams miss entirely.
Too soon
Misjudged prognosis leads to the early withdrawal of life-sustaining care — the leading cause of death in the neuro-ICU.
Invisible
Today's tools can't continuously see the brain. Critical decisions are made on incomplete information.
Our answer
A better way to diagnose
A better way to diagnose
and triage ICU patients.
Vigil turns the bedside into a window on the brain — giving clinicians objective, continuous evidence to act with confidence.
Completely non-invasive
No surgery, no implants. Vigil sits gently on the head and works through the skin — safe for any patient, any unit.
Real-time brain insight
Continuous, decodable neural signals — see how the brain responds the moment it happens, second by second.
Hears those who can't act
Vigil detects responses from patients who cannot move or speak — surfacing the awareness behind the silence.
The science
How Vigil listens
How Vigil listens
to a silent brain.
From signal to insight in three steps — designed to give clinicians an answer they can trust.
-
Step 01
Sense
A non-invasive headset captures high-resolution brain activity continuously at the bedside — no implant, no disruption to care.
-
Step 02
Decode
Our neural models translate raw signals into meaningful markers of awareness, command-following, and cognitive response.
-
Step 03
Decide
Clear, objective evidence reaches the care team in real time — informing diagnosis, triage, and the most consequential decisions.
Vigil One.
A non-invasive headset that quietly, continuously understands the brain — and what the patient cannot say.
Real-time decoding at the bedside. The answer, when it matters most.
Pioneers wanted.
We're partnering with the teams who will define the future of critical care.
Give every patient
a voice.
