The Origin Story

From garage project to global movement

In 2016, I started building electric hydrofoils in my garage and sharing everything on YouTube. No patents, no paywalls — just open designs and honest build logs.

That decision kicked off a worldwide DIY eFoil movement. Builders from 50+ countries started modifying, improving, and sharing their own designs. FOIL.zone became the hub.

The eFoil itself was invented in 2008 by Jakob Kuttenkeuler at KTH Stockholm — the first person to combine a foiling surfboard with electric propulsion. My contribution was making it accessible to everyone.

Today, the mission continues: build tools that help people build things. Open source. Free forever.
