Company Overview

Last Updated:

March 24, 2026

Develops tankless, battery-powered dive gear using electrolysis to extract oxygen from water, enabling breath autonomy across sea, land, and space environments.

Competitive Advantage & Moat

Product Roadmap & Public Announcements

Three-domain positioning: sea (diving), land (firefighting, medical), space (life-support). Modular, battery-powered electrolysis as core platform technology.

Signals & Private Analysis

Prototype testing with military divers and possible astronaut programs. ML likely required for gas mixture optimization and real-time safety monitoring. Very small team, possibly bootstrapping with defense contracts.

Product

Real-time ML-driven optimization of breathable gas mixture output from electrolysis, adjusting oxygen and humidity levels based on diver physiology and environmental conditions.

In Plain English

The device uses AI to constantly tweak the air you breathe underwater so it's always safe, like a smart thermostat for your lungs.

Analogy

It's like having a sommelier for your lungs who instantly knows whether you need a bold red or a light white based on what you're doing, except instead of wine it's oxygen and getting it wrong means you pass out.
