About us

We are a European scale up dedicated to developing cutting‑edge, automated wind‑assisted propulsion systems. Our goal is to provide a turnkey solution for shipowners and shipping companies who seek to reduce fuel costs and emissions. Our vision is simple yet ambitious – we aim to power the world with wind.

Imagine a world where the vast oceans are effortlessly traversed using the clean and boundless power of the wind. At bound4blue, we are turning this dream into reality. We're not just creating wind propulsion systems but revolutionizing the maritime industry, one sustainable voyage at a time. While bringing sails back to ships may seem challenging, we are more than prepared for it. We are innovators who understand the perfect harmony between nature and technology.
