Passive Metabolic Sensing · Coming Soon

YOUR GUT. DECODED. EVERY MORNING.

Your gut has been sending signals all along.
For the first time, something is truly listening.

Gutfox is a passive sensing device that reads your metabolic state every morning — gut fermentation, microbiome rhythm, ketosis, motility — without changing a single thing about your life. No wearable. No blood. Nothing to remember.

The Problem

The most important metabolic signals your body produces happen daily.
You've never been able to measure them.
Until now.

Scales miss it. Bloodwork snapshots it once a year. Breath tests require effort and mail-ins. Wearables track your wrist, not your gut. For decades, the richest metabolic data your body generates has passed, unread, every single morning. Gutfox changes that — passively, automatically, for every person in your household.

Passive

Gutfox works in the background, every day, without asking anything of you. No app to open. No test to take. No logging. No compliance. It simply works — while you do everything else.

Zero behavior change required

Precise

Six metabolic biomarkers. Simultaneously. Every session. Powered by industrial sensing technology developed over decades for applications where failure was not an option — now applied to your gut health.

6 simultaneous biomarkers

Personal

Your gut is unique. Gutfox builds a longitudinal baseline that is specific to you — learning your patterns over days and weeks until the insights become genuinely predictive, not just descriptive.

What Gutfox Reads

SIX SIGNALS.
ONE MORNING.

Every session produces a chemical fingerprint. Gutfox decodes all of it.

H₂

CH₄

NH₃

Amines

H₂S

Acetone

H₂ Hydrogen

Gut Fermentation

How intensely your microbiome is fermenting. A sensitive daily marker for dietary response and gut activity patterns.

CH₄ Methane

Motility Phenotype

Reveals your gut's motility pattern. Stable across days — the signal that builds your personal metabolic baseline fastest.

NH₃ Ammonia

Protein Metabolism

Reflects protein utilization and hydration. Also the timing anchor that lets Gutfox align all other biomarker readings precisely.

Amines

Microbiome Health

Sensitive to microbial composition shifts and dietary changes. Adds critical depth to multi-signal pattern recognition.

H₂S Sulfur

Inflammation Signal

Low concentration. Extremely high diagnostic value. The signal most approaches can't even detect — Gutfox reads it every session.

Acetone

Ketosis & Metabolic Flex

A slow-moving trait signal — reflects systemic ketosis across days. Maps your true metabolic state over time, not just in the moment.

"A fox doesn't try to smell the world. It simply does — always, automatically, with extraordinary precision."

— The reason we chose the name

Foxes possess one of the most sophisticated olfactory systems in nature — detecting chemical signals at concentrations imperceptible to humans, building a continuous picture of their environment without effort or intention. That is exactly what Gutfox does for your metabolism: passive, precise, always-on intelligence that requires nothing from you.

NOSE OF A FOX

Sensing technology developed for applications where sub-parts-per-million detection at 100% humidity was non-negotiable. Applied now to the six biomarkers your gut produces every morning.

MIND OF A FOX

AI metabolic scoring that learns your specific patterns — not population averages. Over time, Gutfox knows what high fermentation means for you, what your ketosis baseline looks like, what normal is for your microbiome.

INSTINCTS OF A FOX

The insights that matter most are the ones you don't have to ask for. Gutfox surfaces what's changed, what's trending, and what to pay attention to — before you think to check.

TECHNOLOGY BUILT FOR THIS.

Gutfox is powered by an industrial sensing platform developed over decades for environments where measurement failure was not an option — proven across 29 gases in government defense and energy programs. Exclusively licensed for toilet-based wellness sensing. No other consumer device can do what Gutfox does here.
