MEET OUR FOUNDER

The future of prevantive health

“For decades, the tools required to understand the inside of the body were locked inside hospitals. Ordinary people had almost no access to their internal health.

LIGHT is the first step toward a future where checking your health is as effortless as checking the weather.

A future where early disease detection, metabolic mapping, and full-body optimization happen in seconds, not weeks.”

I thought I was healthy because I was lean
I always thought I was healthy because I was lean. The Light showed I had dangerous visceral fat around my organs. Being able to track it weekly helped me reduce it.

Rita C.
Better metabolic health!
This is the first time I’ve felt like I can truly see what’s going on inside my body, not just my weight. Watching my metabolic health score improve has been incredibly motivating!

Emil K.
Less ectopic fat
My old smart scale told me everything was fine. LIGHT showed elevated ectopic fat and metabolic risk. I made the recommended changes, and feel and look wayyyy different

Emina L.
Decrease in inflammation
For the first time, I could track changes happening inside my body. Watching my inflammation decrease over time gave me confidence I was improving my long-term health.

Questions? We're here to help.

What is LIGHT?

LIGHT is a clinical-grade body scanner designed for the home.

Unlike traditional smart scales that estimate your health from surface-level data, LIGHT uses our proprietary Deep Signal Imaging™ technology to map how biological signals move through your internal tissues — including muscle, visceral fat, hydration, and key metabolic indicators.

By reading internal signal patterns instead of relying on external averages, LIGHT delivers DEXA-level precision in tracking your body composition and internal health.

The result is a next-generation body scanner that reveals what’s happening beneath the surface — providing clinical-grade internal insight in seconds, from the comfort of your home.

What is Deep Signal Imaging™?

Deep Signal Imaging™ is the core technology behind LIGHT.

Your body is a network of tissues that conduct electrical signals differently. By sending low, safe signals through the body across multiple frequencies, LIGHT measures how those signals travel internally.

Different tissues — such as muscle, visceral fat, and ectopic fat — create distinct signal patterns.

LIGHT maps these patterns to estimate internal body composition and metabolic health markers that are typically only available through clinical imaging tools.

Is LIGHT just an advanced smart scale?

No.

Other smart scales attempt to estimate your body composition using simple electrical signals and population-based averages, essentially making surface-level guesses about what’s happening inside your body.

LIGHT operates on an entirely different level.

Our proprietary Deep Signal Imaging™ technology reads how signals travel through your deep internal tissues. Muscle, organs, visceral fat, hydration, inflammation markers, and ectopic fat each alter signal flow in distinct ways, creating a unique internal signature.

Rather than relying on external measurements or statistical assumptions, LIGHT maps these internal signal patterns to build a dynamic picture of your inner health.

This is not estimation from the outside.

It’s signal-based insight from within.

How accurate is LIGHT?

LIGHT has been third-party validated against clinical DEXA scans across multiple body composition markers.

In early testing, LIGHT has shown up to 98% accuracy in measuring visceral fat, muscle mass, and total body composition trends when compared to DEXA.

Who is LIGHT for?

LIGHT is designed for people who want to:

- Reduce fat and improve body composition

- Track internal health over time

- Understand metabolic health beyond weight

- Understand risk factors

- Detect patterns of biological decline

- Improve longevity

- Optimize long-term health and performance

How often should I scan?

LIGHT is designed for daily or weekly use.

Tracking trends over time provides more meaningful insight than occasional one-off measurements.

Can LIGHT detect disease?

LIGHT is not a diagnostic medical device and does not diagnose disease.

However, it can detect patterns associated with metabolic risk — such as excess visceral fat, liver fat probability, or impaired insulin sensitivity — which are often linked to long-term health outcomes.

Does LIGHT come with a free app?

Yes.

Every LIGHT device includes access to our free companion app, which provides essential daily tracking of your internal body composition and metabolic health trends.
