bound4blue lands US$44M from investors eyeing wind power as scalable maritime solution

bound4blue, a global leader in wind propulsion systems, has closed a US$44 million funding round backed by leading maritime corporates, ship owning families, climate-focused investors and government capital.  

The round was led by OCTAVE Capital, an investment platform affiliated with major shipowner: IMC, and Katapult Ocean. The round brings together new investors including Motion Ventures, Odfjell family office and ReOcean Fund - led by the Prince Albert II of Monaco Foundation and Monaco Asset Management - alongside existing investors Shift4Good, GTT Strategic Ventures, KAI Capital and CDTI (Innvierte SICC), who strengthened their commitment to the company. 

“This round signals a new phase for bound4blue,” said José Miguel Bermúdez (pictured), CEO & Co-Founder of bound4blue. “Earlier stages focused on proving the technology and validating its impact; now this new capital reinforces the long-term backing we already have from investors who understand shipping and share our industrial vision and the role this technology will play across the fleet.

 “This funding enables us to expand capacity, accelerate our growth roadmap and advance new developments that will elevate both the technology and our services to the next level. It confirms that bound4blue is built on solid foundations and positioned for sustained global deployment,” he added. 

The investment underscores a growing industry consensus: suction sails are emerging as a leading pathway for immediate, scalable decarbonisation across the global fleet with commercial gains.  

The new funding will accelerate bound4blue’s shift into full industrialisation of suction sails and support efforts to deepen R&D as the company looks to grow beyond existing commercial offerings. The company is also responding to increased market demand by expanding manufacturing capacity to supply hundreds of suction sails annually.
