THE WORLD JUST CHANGED

Claude Health launched January 11, 2026. ChatGPT Health launched January 7. Within five years, everyone will have a personal health AI that knows their body better than any system.

These AIs need data. Continuous. Raw. Real-time.

They're not getting it.

────────────────────────────────────────

THE DATA STARVATION PROBLEM

Current wearables were built for humans looking at dashboards. Oura gives you a "readiness score." Whoop gives you a "recovery score." Apple Watch gives you rings.

Summaries. Aggregates. The signal compressed into a number.

When Claude asks "Why does this person feel bloated after dinner?", Apple Health says: Activity: 8,432 steps. Sleep: 7h 12m.

Useless.

The AI needs the raw physiological signal. The subtle patterns. The continuous stream. No wearable provides it.

────────────────────────────────────────

WHAT WE BUILT

A multi-sensor wearable that streams raw physiological data to AI health assistants.

The hardware: Acoustic sensor. HRV. Temperature. Motion. 7-day battery.

The platform: MCP server for Claude. REST API for ChatGPT. WebSocket for real-time streaming. Your health AI gets continuous context, not daily summaries.

We didn't build a dashboard company. We built infrastructure.

────────────────────────────────────────

THE GUT ENTRY POINT

Why gut? Because it's the biggest black box in health:

• 40% increase in sleep disruption from late-night digestion
• 50% of athletes get GI distress during competition
• 65% of GLP-1 users quit due to GI side effects

Acoustic gut monitoring has decades of peer-reviewed validation. What changed: MEMS microphones got small enough. Edge ML got fast enough. And this month, AI health platforms launched.

The timing aligned. We built it.

────────────────────────────────────────

THE RAW DATA MOAT

                OURA            WHOOP           SUNA
                ────            ─────           ────

AI access       Apple Health    Apple Health    MCP + REST API
Built for       Dashboards      Dashboards      AI agents

None of the wearables give RAW data. They all aggregate and summarize. That subtlety is exactly what AI needs for true personalization.

────────────────────────────────────────

TWO PRODUCTS, ONE PLATFORM

For consumers: Your gut activity mapped against meals, workouts, sleep. Discover which foods work for your body. Know when you're ready to train. See whether dinner wrecked your recovery.

For AI: When Claude asks a question, SUNA provides the context. The AI reasons. You get answers.

Same data. Two interfaces. One built for you. One built for your AI.

────────────────────────────────────────

THE MARKET

Today: Athletes who want data. Biohackers who track everything. People trying to lose weight who need data.

Tomorrow: Every AI health company that needs continuous data to make their product work.

We're not competing with Oura. We're building infrastructure they'll eventually need.

────────────────────────────────────────

VALIDATION

UCL Centre for Human Health and Performance, Prof Hugh Montgomery OBE is chief scientific advisor.

95% accuracy classifying bowel sounds. Multi-modal sensor fusion on top.

────────────────────────────────────────

THE WINDOW

The US just deregulated health data for AI (HTI-5, December 2025). Claude Health and ChatGPT Health launched the same week. The infrastructure moment is now.

First mover advantage in "wearables for AI" is available for exactly this window.

We're taking it.
