The story behind BRAIN

BRAIN was born from our own passion for cold immersion therapy and the frustration we felt with the existing solutions. As regular users of cold plunges, we realized that most setups were either too basic, unsafe, or required complicated installations with lots of cables and external devices. We wanted something smarter, safer, and easier to use.

The idea for BRAIN came to us one winter morning after yet another session where the water wasn’t at the right temperature and the filtration system failed again. We thought: “There has to be a better way.” That’s when we decided to create a device that would bring together all the essential functions—temperature control, filtration, ozone purification, and smart automation—into one compact, user-friendly unit.

The journey wasn’t easy. We spent months prototyping, testing, and refining the design. We faced technical challenges, especially in making everything fit into a minimal size without sacrificing performance. But our commitment to quality and innovation kept us going.

Today, BRAIN is the result of that journey: a device that transforms any cold plunge into a smart, safe, and efficient experience. We’re proud to help people get the most out of their cold immersion practice, whether they’re athletes, wellness enthusiasts, or anyone looking to improve their health.

Our mission is to make cold therapy accessible, enjoyable, and worry-free for everyone. And this is just the beginning.
