THE PROBLEM

40% increase in sleep disruption odds from late-night digestion.

50% of athletes get GI distress during competition. Nutrition timing is the main modifiable cause.

65% of GLP-1 users quit treatment. GI side effects are the primary driver.

Gut health is a black box. No real-time wearable exists.

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

THE DEVICE

A sensor. 7+ days battery. MEMS microphone on the abdomen. Captures bowel sounds 24/7.

Edge AI classifies digestive states. No cloud. No data leaves your phone.

Output: actionable gut metrics. Your digestive readiness and activity relative to your baseline.

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

THE SCIENCE

Acoustic gut monitoring isn't new. Peer-reviewed research spans decades:
• Bowel sound frequency correlates with motility state
• Post-meal activity is measurable and classifiable
• Sleep-stage differences are detectable acoustically

What's new: MEMS microphones got small enough. Edge ML got fast enough. We built it.

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

WHAT YOU SEE

Your gut activity. Continuous. First time this exists outside a clinic.

Digestion mapped against meals, workouts, sleep.

You discover:
• Which foods work for your gut
• How long until you're ready to train
• Whether dinner wrecked your recovery and sleep

The data was always in your body. Now it's on your phone.

MARKET

Athletes who want data. Biohackers who track everything. Anyone on Ozempic who can't keep it down.
