About us - Tummo

— OUR STORY

We built the thing we desperately wanted ourselves.

Tummo exists because anxiety is physiological — and every solution we tried assumed we had the calm to use it. We knew there had to be a better way.

Calm shouldn’t be something you achieve. It should be something your body simply returns to. That’s what we set out to build.

WHAT WE BELIEVE

The principles that guide everything we build.

01 Effortless by design

If a wellness tool requires willpower to use, it fails the people who need it most. Everything we build works in the background of your life — not on top of it.

02 Evidence, not intuition

Every feature in Tummo is rooted in peer-reviewed research. We don’t ship wellness theatre — only mechanisms with measurable outcomes backed by published science.

03 Privacy by default

Your breathing data is yours alone. We built Tummo from the ground up with data minimization in mind. We never sell your data, and we never will.

04 Real-time over retrospective

Most wearables show you what happened. Tummo acts on what’s happening now — intervening in the moment before stress compounds into anxiety.

05 Honest about what we are

Tummo is a wellness device, not a medical device. We won’t overstate what we do. We’ll just keep building something that quietly, reliably works.

06 Long-term change over quick fixes

Stress relief shouldn’t require you to keep buying subscriptions forever. We want to actually retrain your nervous system — so you need us less over time, not more.

OUR MISSION

To make calm the default, not the destination.

We believe the nervous system is trainable. We believe technology should work quietly in the background of your life, not demand your attention. And we believe that real change doesn’t come from willpower — it comes from building the right conditions for your body to heal itself.

Scientific Foundation

Not opinion. Evidence.

Tummo's core mechanism is backed by three independent peer-reviewed studies from institutions including Stanford University.

Your Nervous System Can Relearn Calm

Slow breathing activates the body’s natural “rest and digest” response — improving emotional stability over time.

Frontiers in Human Neuroscience

Lower Cortisol. Lower Anxiety.

Deep breathing has been shown to reduce cortisol and measurable stress markers linked to chronic anxiety.

Psychoneuroendocrinology

Works Faster Than Meditation

Structured breathing improved mood and reduced anxiety more than mindfulness meditation in clinical studies.
