I used the vibration "anchor" to sway my thoughts into gratitude in whatever situation I was in.

A WORD FROM THE FOUNDER
Hannes Jersenius, CEO at Sou
I have been practicing mindfulness for more than seven years. But with all the distractions of modern life, I often feel that I lose presence and get stuck on auto-pilot. When wearing my Sou, the Moments really help me manage stress proactively and connect deeper to my experience, myself and the people around me. I'm excited to share it with you.
Frequently Asked Questions
What is the purpose of Sou?
To bring you back to yourself, a few seconds at a time. Most of the day runs on autopilot, and by the time you notice, the day is already gone. Sou interrupts that — gently, physically, without asking anything of you. It’s not a tracker and it’s not a coach. Just a quiet nudge to return.
What is Sou, exactly?
A piece of jewellery with a quiet pulse inside. Wear it as a bracelet, anklet, or necklace — the straps are exchangeable, so it fits whatever you’re wearing. No app, no screen, no tracking. Just a reminder, built into something you’d wear anyway.
Is Sou a real company?
Yes. Sou is made by EQUANIMITIES, S.L., a company registered in Barcelona, Spain (CIF B75465542), founded by Hannes Jersenius. Sou was funded on Kickstarter in 2026 by 313 backers, and ships from warehouses in the US and Spain. You can see the campaign and reach us at hello@joinsou.com — we answer.
How does Sou know when to remind me?
A small pulse inside the pebble gives you a smooth, brief vibration at 30–60 min intervals (randomised) throughout the day — close enough together to stay with you, spaced out enough that it never feels routine. You don’t set anything. It just happens.
Does Sou need an app or Bluetooth?
No. No app, no pairing, no screen, no account. You put it on and it works. That’s the whole experience.
How is Sou different from a smart ring or a meditation app?
A smart ring asks you to open an app and read data about yourself. A meditation app asks you to set aside time and sit down. Sou asks for neither. There’s no screen, no session, no log to check — just a reminder, built into something you already wear. It’s not a calmer way to track your stress. It’s a way to stop needing to.
