“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 & 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 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. 

Operational data continues to confirm the scale of impact bound4blue’s systems have had across several fleets. The company has already installed its technology on seven vessels, with a further twelve ships in the orderbook - representing more than fifty sails in total. These projects span leading owners such as Maersk Tankers, Eastern Pacific Shipping, Odfjell, Klaveness Combination Carriers and BW Epic Kosan, reinforcing bound4blue’s position as a preferred partner for forward-thinking players across the sector.  

By 2027, the company is expected to deliver annual CO2 savings of more than 400,000 tonnes, with over 570,000 tonnes avoided in total between 2024 and 2027 - the equivalent of removing around 87,000 passenger cars from the road each year, planting more than 18 million trees, or avoiding over 250,000 transatlantic flights. This will be done through parallel production lines in Spain and China, enabling higher production throughput, stronger supply-chain resilience and faster delivery schedules.

By generating additional thrust from wind power, bound4blue’s suction sails ‘eSAILs®’ reduce engine loads and fuel consumption, cutting vessel operating costs (with double digit savings) and CO2 emissions.

Independently verified results demonstrate consistent, tangible impact in service. On VILLE DE BORDEAUX, third-party assessments reported daily fuel savings of 1.7 tonnes, with peaks reaching 5.4 tonnes.  Separately, on Odfjell’s BOW OLYMPUS, the system delivered average fuel-saving of 15-20%, with voyage-leg peaks of up to 40% reductions during its first transatlantic voyage. Verified under full operational conditions, bound4blue’s suction sails are delivering real savings today on vessels trading globally.
