Origin
Jan & Carina · Founders of Vitalkultur
When our son Carlon was born on a January night in 2026, breathwork became more than a technique — it became the way we stayed grounded together.
We couldn't find an app that matched what breathing actually feels like. So we built one during night shifts — testing thousands of haptic patterns to find the perfect rhythm for every breath.
One night, the family was asleep. I put CARLON on the lowest haptic level — barely there, just a whisper on my wrist. Coherence breathing, 5.5 breaths per minute. The vibration was so subtle that I had to listen for it. And that's exactly what pulled me out of my head. No thoughts about code. No plans for tomorrow. Just the faintest pulse, rising for inhale, falling for exhale. I fell asleep mid-session.
That was the moment I knew it works. Not because of the data — but because I stopped thinking and started breathing. Named after our son, because freedom is in every breath.
