Open biosensors. Your data pays you.

Open hardware. User-owned biometric data. Onchain payouts.

April 2026 //////// Presented by Carol Calin

An open hardware platform for continuous biometric data.

Light-based wearables. Open schematics. User-owned data. Onchain rails to pay contributors.

Hardware

Wearable shipped. Version 2 in production.

Light-based headband & armband. 4 circuit boards manufactured and tested.

Software

Upload. Train. Get paid.

Web app for raw sensor ingestion, model training, and onchain reward claims.

Paired dataset

First open biometric dataset of its kind.

Open-sourced paired light-and-glucose data with reproducible ML pipelines. First beachhead: glucose-trend prediction.

Wear the device. Own your data. Get paid when it’s used.

Three properties that closed competitors can’t copy without killing their business.

OPEN

Schematics and firmware on GitHub. Anyone can build, improve, or audit.

<$500/unit · contract manufacturing

YOURS

Data stays on your device unless you share it. When you share, you earn.

privacy-first · onchain payout

PROVEN

Every payout is cryptographically verifiable. No trust in the platform required.

zero-knowledge ML · onchain receipts

Why now

Optical sensor cost dropped 10× since 2020. Kernel proved brain-grade optics in research wearables — we ship a consumer biosensor under $500.

First beachhead

Glucose-trend prediction from hemoglobin signals — our first paired dataset benchmarks against Abbott Libre 3.

Device revenue    Data licensing

1. Device sales

D2C at $400–600. No subscription.

2. Dataset licensing

Licensing to universities & labs.

3. Premium app

Wellness tracking. Share & earn opt-in for cooperatively training health models.

The flywheel

Device sales → increase user base → raw data → better models → more sales.

The moat

Open hardware. Private dataset. Incumbents can’t copy without killing sensor revenue. Forks start at zero. We compound per unit shipped.
