Maritime Robotics, member of Ocean Autonomy  Cluster and a leading provider of autonomous maritime systems, today announced a €28 million growth investment led by Mustard Seed + Partners (MS+PARTNERS), alongside existing investors EnvisionTech, Nysnø Climate Investment, and Umoe, as well as founders, employees and early backers.

The ocean covers more than 70% of the planet’s surface and is essential for global security, commerce, energy systems and climate understanding. Yet conventional manned vessels remain constrained by high cost, safety risks, and operational inefficiencies – restricting the ability to explore, monitor, and safeguard the marine environment at scale.

These constraints are driving a structural shift toward unmanned and autonomous maritime systems. Purpose-built sea drones allow for persistent, cost-efficient, and lower-risk operations across a wide range of applications, including offshore energy, hydrography, environmental monitoring, fisheries management, and maritime security & defense.

Maritime Robotics operates at the center of this structural transformation, offering integrated sea drone solutions combining autonomous navigation, vessel design, and modular payload systems for mission-critical operations.

We are now past the experimentation phase. Across both commercial and defense markets, we are seeing structural adoption of autonomous maritime systems, with customers shifting from pilot projects to fleet-level deployment strategies. This fundamentally changes the scale requirements of our business. This investment allows us to scale manufacturing and expand our product portfolio to meet accelerating global demand.

– Vegard Evjen Hovstein, Co-Founder & CEO of Maritime Robotics AS

With a proven track record of successfully delivering hundreds of autonomous systems, Maritime Robotics is a trusted partner to industrial and defense customers worldwide. The company has demonstrated strong commercial momentum, with revenue growing nearly five-fold over the past five years and more than doubling over the last two years, reflecting accelerating structural demand for scalable, cost-efficient, safer, and lower-emission autonomous maritime systems.

Maritime Robotics has established a leading position in maritime autonomy, with proven deployments across demanding dual-use environments. The combination of modular platform architecture, reliable autonomous navigation, and a strong operational track record creates a scalable foundation for international expansion. We are excited to partner with Vegard and the team to support the company’s next phase of growth – building a global leader in maritime autonomy.

– Stanislas de Joussineau, Co-Founder & Managing Partner of MS+PARTNERS

MS+PARTNERS led the investment based on its conviction in Maritime Robotics’ technology leadership, commercial traction, and differentiated position at the intersection of autonomy, AI, and mission-critical maritime operations, with a clear opportunity to build a category leader delivering meaningful gains in productivity, safety, and emissions reduction. The investment also saw continued support from the company’s existing investor base.

This transaction marks an important step in the company’s scaling journey, bringing in MS+PARTNERS as a strong growth partner alongside the existing shareholder base. Their experience in scaling industrial technology businesses internationally will be highly valuable as Maritime Robotics enters its next phase of expansion.
