Bound4blue, a global leader in wind propulsion systems, has closed a $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.
New investors include Motion Ventures, the Odfjell family office and ReOcean Fund – led by the Prince Albert II of Monaco Foundation and Monaco Asset Management – alongside existing backers Shift4Good, GTT Strategic Ventures, KAI Capital and Spain’s CDTI (Innvierte SICC), which increased their commitments.
“This round signals a new phase for 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,” said José Miguel Bermúdez, CEO and co-founder of bound4blue.
“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 company said the investment reflects growing consensus that suction sails represent a commercially viable and immediately scalable option for reducing fuel consumption and emissions across the existing fleet.
The funding will support bound4blue’s transition to full industrial production, expanded R&D activity and increased manufacturing capacity, as the company prepares to supply hundreds of suction sails per year in response to rising demand.
