Delair Marine

What Delair Marine does

Delair Marine (formerly Notilo Plus), headquartered in Marseille, France, designs and sells the Seasam ecosystem — autonomous underwater drones, a motorized Navigator buoy, mission-control software, and a cloud analytics platform — for industrial underwater inspection and data collection. The core product is a compact 2-in-1 drone that operates as both a wireless autonomous underwater vehicle and a tethered ROV, equipped with seven thrusters, proprietary acoustic communication/positioning, DVL-powered hull servoing, AI-assisted target recognition and tracking, and integrations such as Waterlinked underwater GPS.

The company serves enterprise and government buyers across shipping (CMA CGM, Corsica Linea), offshore energy (via exclusive distributor Cybernetix/Technip Energies), testing/inspection (Bureau Veritas), infrastructure (Vinci Construction, Egis, Enedis), defense (INPP), and scientific research (Ifremer). Revenue is generated through custom-quoted hardware sales, subscriptions to the Delair Cloud platform, and professional services including custom drone development and inspection work, with go-to-market combining direct enterprise sales and a regional distributor network spanning Europe, Japan, and global oil & gas.

Delair Marine is a business unit of DELAIR SAS following DELAIR's December 2022 acquisition of Notilo Plus. Manufacturing is conducted through EFI Automotive Service in Joinville, France, with 80% of procurement value sourced from French suppliers. The company has received institutional backing from Bpifrance (F3A fund), Turenne Capital, Région Sud Investissement, and an EMFF grant for the SEASAM-AI project, and reports a headcount in the 15-25 range.
