Built for the ICU
A purpose-built medical device that lives at the bedside — designed for the realities of critical care, not the lab.
See the mind
the body can't show.
Revealing awareness, intent, and thoughts for people who can't.
Decoding neural activity in real time
0
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.
