Spanish maritime technology developer bound4blue has successfully closed a $44 million funding round backed by a mix of global investors a move that signals growing confidence in scalable wind-assisted propulsion technologies for decarbonising the shipping industry. The round was led by Octave Capital, a Singapore-based investment platform with links to Singapore’s IMC and Norway’s Katapult Ocean, and included a range of strategic new and existing backers. Among the new investors participating were Motion Ventures, the Odfjell family office, and the ReOcean Fund a climate-focused vehicle led by the Prince Albert II of Monaco Foundation and Monaco Asset Management. Existing supporters - including Paris-based Shift4Good, GTT Strategic Ventures, Spanish firms KAI Capital and CDTI (Innvierte SICC) also doubled down on their commitments. Founded in 2014, bound4blue develops automated wind-assisted propulsion systems called eSAIL® suction sails that harness wind energy to cut fuel consumption, emissions, and operating costs for commercial vessels. The technology already installed on multiple ships has demonstrated significant fuel savings and efficiency gains, extending its appeal among shipowners looking for immediate decarbonisation benefits while broader fuel transition solutions evolve. The company has already equipped seven vessels with its suction sails and maintains a healthy order book - including 12 additional installations expected as demand from fleet operators continues to grow. As part of its expansion, bound4blue will use the fresh capital to advance production, scale deployments, and pursue broader commercialisation of its wind propulsion technologies across global shipping markets. Bound4blue’s CEO and co-founder José Miguel Bermúdez, highlighted that this funding round represents a new phase of strategic backing from investors who understand both the maritime sector and the long-term role that wind propulsion can play in reducing emissions across the fleet. #WindPropulsion #Decarbonisation #Shipping #SustainableShipping #bound4blue #MaritimeTech #ESAIL #GreenShipping #FuelEfficiency #ClimateTech #CleanMaritime #EnergyTransition #AlternativePropulsion #MaritimeInnovation #OceanInvesting
