Dry hands, before the sweat starts.
Varuna is the world's first non-invasive wearable for palmar hyperhidrosis. Worn like a watch, it gently stimulates the nerves at your wrist and stops the sweating signal before it reaches your palm. No surgery, no injections, no drugs, and you can take it off anytime.
Sweating far beyond what the body needs, and no treatment that fits.
Palmar hyperhidrosis gets in the way of writing, using a phone, shaking hands, and many kinds of work. The options people have today each come with a real cost.
Antiperspirants
Often not strong enough for severe cases.
Iontophoresis
Needs sessions repeated again and again.
Botulinum injections
Painful in the palm, and must be repeated.
Sympathectomy
Irreversible surgery that can cause sweating elsewhere.
A world first
The first non-invasive wearable for hyperhidrosis. Removable, and acts before sweating begins.
The first device to reach the nerve before the sweat reaches the skin.
Varuna sits over the median and ulnar nerves, the two nerves that carry the sweating signal to the palm.
Sense
Skin-conductance (GSR) and temperature sensors at the wrist track early signs that sweating is coming.
Predict
A model calibrated to each wearer decides when an episode is about to begin.
Stimulate
Two electrodes over the nerves deliver gentle stimulation before sweat appears.
Worn like a watch. Off whenever you want.
Varuna is the world's first wrist-worn device to treat hyperhidrosis through wrist nerve stimulation, and the first treatment of any kind designed to act before sweating begins, not after.

~85%
less palm sweat in a volunteer with severe palmar hyperhidrosis.
A single-participant, preliminary result. Our pre-clinical device trials are now testing it under clinical supervision.

It started with a friend.
Our best friend has had sweaty palms for as long as we've known him. His test answers smudge before he finishes writing them, and he wipes his hand on his jeans before every handshake. Antiperspirants didn't work, injections were expensive and had to be repeated, and surgery was too big a risk.
We kept asking why there wasn't something he could just wear. So we started building it. Varuna began as a fix for one friend. Now we're building it for everyone who has ever hesitated before a handshake.
Advisors
Clinicians, researchers, partners: let's talk.
We're looking for clinical collaborators, people living with hyperhidrosis who'd like to follow the project, and partners to help bring Varuna to patients.
