Every wearable on the market assumes you sleep at night. V3LA is built for the 20% of the workforce who don't — a single high-signal sensor and a coaching engine that estimates your true internal clock and tells you when to push, when to rest, and how to re-sync.
Consumer wearables compete on how many metrics they can display. We went the other way: measure the two signals that actually carry circadian phase, and spend all the compute on what to do about it.
Distal skin temperature carries a clean circadian signal — its minimum tracks core body temperature minimum, the anchor point of the whole system. Estimate that, and everything else becomes arithmetic: when melatonin rises, when reaction time bottoms out, which direction light will shift you.
Continuous distal temperature and movement, 86,400 samples a day, no user input required.
A limit-cycle oscillator fit per person converges on your temperature minimum within four days — ±19 min against lab DLMO in our pilot.
Sleep, light and caffeine timing solved against your actual roster — the shortest path from where your clock is to where the schedule needs it.
"Fatigue on a night rotation isn't a willpower problem. It's a phase problem, and phase is measurable."
Consumer first, enterprise second, regulated third. Each stage funds the evidence base the next one needs.
V3LA One is a general wellness product. It is not intended to diagnose, treat, cure or prevent any disease, and it is not a substitute for clinical judgement. Programs marked regulated are pre-submission and are not available for sale.
The company started on an overnight rotation, with a spreadsheet and a thermometer. Everyone we've added since has either lived the problem or spent a career measuring it.
15 people, four disciplines, one hypothesis. If you want to own a whole surface instead of a ticket queue, this is that stage — and we're hiring exactly one role right now.
The one role we're hiring. Design and run the validation studies that turn our phase estimate into a defensible claim — including the DLMO comparison work. Publication is part of the job, not a side project, and the hiring process is thorough by design.

Every large wearable company is optimised for a diurnal user and monetised through a general-purpose subscription. Serving irregular schedules properly means a different sensor set, a different model, and a different buyer — including the health systems already paying for fatigue-related error.
Pilot cohorts open monthly for clinicians, night-shift teams and rotating-schedule workers. Investors and press: same form, we route it.
