Hydromea is a Swiss deep‑tech spin‑off from EPFL in Lausanne, founded in 2014 to “cut the cord” on underwater asset inspection and monitoring. Its team of engineers and roboticists has created a suite of compact, battery‑powered underwater drones and optical wireless modems that enable real‑time high‑definition video and data transmission beneath the waves.

By combining proprietary LUMA optical communications modems with lightweight hubless thrusters and an untethered ROV platform (ExRay), Hydromea addresses longstanding limitations of subsea operations – such as the risk and expense of tethered inspections – in a novel way.

This analysis answers: How do Hydromea's LUMA optical modems, hubless thrusters and untethered ExRay ROV cut the underwater cord? How mature is the EPFL-derived subsea technology and its defence/dual-use fit? What customers and partners adopt Hydromea's wireless subsea inspection over tethered methods? What capability gaps and dependencies face this 2014 Swiss spin-off?
