Nafsy is a wearable that helps your body find calm when stress takes over. Designed for real life.
A haptic bracelet for real-time stress relief — through breath, rhythm and touch.
First units in production · Backed by science · Pilot program 2027
Discreet, premium, screen-free. Worn like jewelry.
Sends a gentle haptic rhythm to your wrist to ease stress in the moment.
Slow vibrations guide your breath and help your nervous system settle.
FOR THE MOMENTS YOU CAN'T EXPLAIN
Stress doesn't always come with words. Sometimes it's just a tightness, a racing pulse, a feeling you can't quite name. Nafsy is there for those moments.
Before an exam, when your heart races before you've even started.
In a crowded room, when you need to stay composed.
Late at night, when your mind won't slow down.
In the middle of a day that's moving too fast.
Three steps. No effort required.
When stress rises, press your bracelet.
A slow, breath-paced haptic wave begins — gentle and silent.
Your breath follows the rhythm. Your body returns to calm.
Nafsy's protocol is developed with input from a multidisciplinary scientific committee:
Neuroscience researcher — CNRS / ENS Ulm
Pharmacist — neurochemical regulation
Acupuncture physician — somatic and autonomic regulation
Strategic Advisor — Corporate Partnerships & Workplace Adoption
Technical Advisor — Electronics engineering educator
A randomized, intra-subject study is planned for our 2027 pilot program (12–20 participants, 3 haptic stimulation conditions).
Nafsy is inspired by published research in psychophysiology. It is a wellness wearable, not a medical device.
Signals from the people who need this most.
“In investment banking, stress is somewhat normalized — the solution needs to avoid stigma and stay very discreet.”
“I have an Apple Watch, but I took it off. The 'Breathe' notifications always came at the wrong moment — it annoyed me more than anything.”
“Scientific credibility is essential, especially for health professionals like me.”
“My ideal solution would be a delicate piece of jewelry — an elegant bracelet — that stays completely silent to others.”
“The main barrier would be the price-to-benefit ratio, especially for someone who isn't very stressed.”
Nafsy started from watching the stress on the trading floor during her internship at Société Générale, and asking why no one had built something to help with it in the moment.
