Origins

The idea started while diving. I surfaced, sat in a coffee shop, and asked a simple question: fish breathe underwater without tanks - why can’t humans? Diving gear is heavy, complex, and logistically constrained, yet the surrounding water already contains the oxygen we need. I looked into the physics and realized this wasn’t a biology problem, but an energy problem. By applying electricity to water, it’s possible to generate breathable oxygen on demand. That insight led me to start DAIVIN!. With support from my family and people along the journey, I committed full-time to turning that idea into a working system!
