Hydromea
EPFL spin-off building compact underwater inspection robots and the wireless subsea technology to free them from tethers: its EXRAY ROV inspects flooded infrastructure and ship/offshore assets, streaming live HD video over Hydromea's proprietary LUMA optical modems for tetherless operation. The company reports more than 50 global customers and signed a strategic distribution agreement with MFE Offshore covering offshore and maritime markets, plus a June 2025 partnership with Blue Logic pairing wireless comms with inductive subsea charging for resident underwater robots.
