Why invest
Fuel cost volatility, EU ETS and CII emissions penalties, and incoming antifouling coating bans are converging to make autonomous hull cleaning an operational necessity.

Hullbot uses autonomous underwater robots to reduce vessel fuel costs through proactive hull cleaning.

  • Hullbot offers ship operators an autonomous hull cleaning service, with customer verified savings of 10-28% on fuel costs. Hullbot designs, manufactures, and deploys a global fleet of underwater robots that are remotely managed, travel with vessels and clean when stationary.

    Delivered as a service with no upfront capex, Hullbot ensures fuel savings exceed the service cost. Frequent, proactive cleaning outperforms antifouling coatings, diver services and drydocking on both cost and performance.

  • Biofouling, marine growth on ship hulls, drives higher fuel and operating cost for fleets. It accounts for 1% of global emissions, is the primary pathway for invasive marine species, and poses an escalating regulatory risk to port access.

  • Commercial operators with high-utilisation fleets - passenger ferries, workboats and cargo ships.

    • AU$16M Series A in 2025 from lead investor Regeneration.VC
    • Operating commercially across EU, LATAM, US, and APAC
    • 1,800+ cleans across 91+ vessels, saving 2m litres of marine diesel and 6m kg CO2e
