Our 2025 round-up of the largest funding rounds in maritime, marine tech, and ocean innovation highlights a banner year, with startups securing over $180 million in combined investment.
From electric drivetrains and zero-emission hydrofoils to AI-powered navigation and digital fleet management, these companies are driving the next generation of sustainable, high-tech ocean solutions.
A clear trend emerges, investors are prioritising clean propulsion, automation, and digitalisation. Larger Series A rounds dominate hardware-heavy, deeptech projects, while smaller seed and pre-seed rounds support software, platform, and fleet management startups.
