Spicetek, in one page.
A product company since 2017. We build products and sell them — and right now we're proving it with our own.

01 — Building
SleepShutter: an iPhone app that records the night
Records snoring through the night and saves the video and audio around each event, with night vision for a dark room. Processing stays on the phone — nothing is uploaded to us or to anyone else.
Stated plainly
What it doesn't do
SleepShutter does not diagnose, and it does not replace a sleep study.
It has not been measured against a reference standard. Our accuracy figures so far come from our own hand-labelled recordings and a held-out test set — internal, not validated against polysomnography.
02 — Status
Where it stands
Runs overnight in real bedrooms
Recording, night vision and the morning timeline all run on the phone.
1.0 submitted to the App Store
SleepShutter 1.0 was submitted for App Store review on 28 October 2026. The TestFlight beta is open to testers in the meantime.
One federal research application
Spicetek has one research application under review at the U.S. National Institutes of Health (NIH).
03 — What we're looking for
Four kinds of people
What SleepShutter is short of isn't ideas. If you're one of these — or you just thought of someone — this page exists so you can forward it.
01
Clinical judgement
In sleep medicine and in dentistry. Someone to review our inclusion and exclusion criteria, and the contraindication list for an intraoral appliance. A consultant role, not a co-investigator one: no subjects to enrol, no patients or records from your institution, and you set the hours and the rate.
02
Reference data
Groups with DISE recordings scored against VOTE, or with PSG and synchronised audio. What we bring is our own annotated overnight event data and a frozen annotation protocol. Co-authorship is on the table.
03
Seed-stage investors and corporate partners
Especially partners who bring manufacturing. Our intraoral appliance is in materials and 3D-printing validation, and that is the weakest part of what we do.
04
A co-founder
Not another person who writes software. Someone from the clinical or dental side.
04 — Contact
What to do
Reply and tell us which one you are — or forward this page to the person you just thought of. Two sentences is plenty. We answer.
The full methods and the figures behind them are available on request.
