Investor overview / October 2026
A clearer picture
of sleep.
DOTVI is developing wearable sleep-health technology that brings physiological signals and machine learning together, with a focus on sleep-apnoea research.
The vision
Make overnight physiological patterns easier to capture and understand, and build evidence for useful sleep-health insights. The long-term ambition is to support a clearer route to appropriate clinical follow-up.
The approach
A screenless wrist-and-ankle research prototype explores continuous ECG contact through integrated dry electrodes, alongside optical sensing for blood oxygen. Signal-processing and machine-learning research examines ECG, heart-rate variability and oxygen patterns. A planned companion app would bring the results into a readable overnight summary, subject to validation and the intended use.
Work under way
- Sleep-study preprocessing and early machine-learning experiments using ECG and oxygen data from the Sleep Heart Health Study (SHHS).
- Investigation of a two-band continuous ECG prototype and integrated dry-electrode contact.
- Development of the pathway from physiological data to candidate sleep-apnoea insights.
Sleep-study model results are an early research foundation. They do not yet establish performance on DOTVI wearable data.
The next milestones
| Phase | Evidence to build |
|---|---|
| Research | A documented evaluation baseline using separate participants and a wearable-data testing plan. |
| Prototype | Measured signal quality, stable contact, electrical safety, battery performance and overnight comfort. |
| Validation | Comparison with reference sleep measurements to assess performance, limitations and robustness. |
| Translation | A companion experience, defined intended use and a clinical and regulatory pathway. |
What the next phase would support
Prototype engineering and sensor integration; wearable-data collection and model evaluation; app development; clinical collaborations and regulatory planning. Funding scope and terms would be discussed directly.
Who we want to build with
Early-stage investors, clinical collaborators and wearable technology partners who share a commitment to evidence-led sleep health.
Development status. DOTVI is in research and prototype development. It is not a validated diagnostic device. Clinical performance, regulatory approval and a commercial launch date have not been established.
