bound4blue raises €5M in financing to lead the implementation of wind-assisted propulsion technology for the maritime transport industry

  • Besides the investment of current shareholders of the company and the support of some public entities, this funding round is supported by some strategic investors such as Aciturri Aeronáutica, CDTI (INNVIERTE), EIT Climate KIC, the Ocean Born Foundation or ARCANO PARTNERS (IMASDE fund), among others.
  • Some weeks ago, bound4blue successfully installed an eSAIL® system on a fishing vessel owned by the Spanish shipowner ORPAGU. The vessel started sailing again after the retrofitting, with the eSAIL® system fully operational.

Santander/Barcelona (Spain), 30 June 2021. bound4blue has successfully raised a funding round of more than €5M, starting a new phase in the development and implementation of its unique wingsail technology (eSAIL®) for the maritime transport industry. As part of the transition towards a more sustainable energy model, while being fully aligned with the objectives of the International Maritime Organization (IMO), the maritime industry is looking for innovative solutions that allow these new sustainability goals to be attained while reducing operational costs. The use of wind power as an auxiliary propulsion method is a natural step in this transition, and that’s why bound4blue is strongly committed to its development and commercialization.

bound4blue embarks on this new phase with the support of companies and strategic investors such as Aciturri AeronáuticaCDTI (INNVIERTE), EIT Climate KIC, the Ocean Born Foundation or ARCANO PARTNERS (IMASDE fund), as well as with the support of public entities such as Government of Cantabria, Sodercan or the European Union. The funds will be used to boost the implementation of the eSAIL® technology, thereby placing bound4blue in a leading position in the €66B wind-assisted propulsion technology market.

José Miguel Bermúdez, CEO, bound4blue: “For bound4blue it’s absolutely key to have onboard the support and experience of our new partners, as well as the renewed support of our previous investors too. This new funding round will allow us to scale up the company and to boost our technology implementation within the industry, thus positioning bound4blue as a market leader to capture the huge turnover that this sector will generate in the upcoming years.”
