Engineering the Future of Electric Foiling

The team behind the world's most advanced eFoil technology.

Our Mission

We engineer electric foiling experiences that stay with you long after you leave the water.

Our mission is to give people a new way to experience the water. One that opens up a sense of adventure you never want to end.

Our Values

Our values are what we stand for. They are built into every board we build, every ride we enable, and every choice we make.

Simplicity

We believe the best experiences feel effortless. That belief drives every product decision we make - stripping away complexity until what remains is exactly what it needs to be. Nothing more. Because simplicity isn't the absence of effort. It's the result of it.

Adventure

We build for people who want to go further. We think about the places our boards will go and the experiences they will unlock. We make design decisions with the rider in mind, not the spec sheet. We live for the moments that are only possible above the water.

Community

We believe eFoiling is better shared. We listen to our riders, learn from them, and build what they actually need. We create spaces for people to connect, share their experiences, and inspire each other on the water. The people who ride our boards make us better. We take that seriously.

Innovation

We never accept the way things have always been done. We question existing solutions, test new approaches, and treat every product as a work in progress. We built the jet drive when everyone said it couldn't be done. That instinct for doing things differently has never left us. Getting better is not optional. It is the job.

Our values are what we stand for. They are built into every board we build, every ride we enable, and every choice we make.

The Story Behind Aerofoils

Dipl.-Ing. Christian Rößler
Franz Hofmann

"We built the jet drive others said couldn't be built. Not because it was easy - because we believed it was right."

"Aerofoils was born from a passion for water and engineering."

Dipl.-Ing. Christian Rößler

Co-founder of Aerofoils GmbH

“How I became part of Aerofoils? I ask myself the same question! But when Franz, accompanied by my brother Hansi, approached me in 2014 to develop a carbon fin for kitesurfing, I found myself tempted. I had won everything in model flying, from several German champion to world champion and finally world record holder. At the university I normally develop my own, innovative aircraft designs, as well as teaching aircraft design. A hydrofoil is essentially an airplane made for water and thus to electify the whole thing is what made the project very exciting for me.”

Franz Hofmann

Co-founder of Aerofoils GmbH

“Personally, imagining life without water sports would simply not be possible. Windsurfing, kitesurfing, paragliding, speedflying and since 2014 hydrofoiling – that’s how the whole thing started.

Fascinated by the technology as well as the encounter with the elements we eventually started to develop our own carbon fins for kitesurfing, which worked perfectly well. As a developer for electric vehicles at Audi it consequently became a dream of mine to build an Audi for water.”

The Next Chapter

What started in a cellar is now backed by one of the world's leading industrial technology groups. Together with Rosenxt, Aerofoils gains the scale, expertise, and long-term R&D commitment to go further than ever. The next chapter starts now.

Built Without Compromise

Great products don't happen by accident. At Aerofoils, our teams work tirelessly to ensure that each board we build meets the same uncompromising standard - from the engineering lab to the water - so that when you fly, nothing holds you back.

Engineering & Development

How we work together

From the first concept sketch to full system validation, our engineering team develops complete hydrofoil experiences, covering mechanical design, electronics, prototyping, and real-world readiness. Precision and structure are not aspirations here — they are the baseline we hold ourselves to on each project.

Engineering & Development

Design

How we shape the experience

At Aerofoils, design is never purely cosmetic. Form and function are developed in parallel, so that every line, curve, and surface finish on the board reflects a deliberate decision. We believe a board should be as compelling to look at as it is to ride, and that the two are never in conflict.

Manufacturing

How we build each board

From carbon fibre layup to final assembly, each Aerofoils board is built with a level of hands-on precision that mass production simply cannot replicate. Backed by the industrial capabilities of Rosenxt, we combine artisan craftsmanship with scalable production standards — ensuring that quality never becomes a casualty of volume.

Manufacturing

Quality Assurance

How we maintain our standards

Quality at Aerofoils is not a final checkpoint. It is built into the process from the very beginning. From incoming components to in-process assembly checks and final sign-off, each board is held to the same rigorous standard. The board that reaches you has been through the same process as the very first one we ever built.

Born in the Cellar

What started in a cellar became an obsession. Armed with ambition and raw engineering instinct, Franz and Christian built Aerofoils' first prototype by hand - a rough proof of concept that a board could fly above water. The dream was real.

From Protype to Product

The moment the board lifted above the surface for the first time, everything changed. Years of engineering, testing, and iteration had led to this - a fully working Aerofoils eFoil, silently gliding above the water. The prototype had become a product.

Founding the Spin-Off

To bring our vision to life we founded the SpinOff Aerofoils GmbH in 2017 to be even more flexible and agile. To be known to a wider public we present our e-foil together with Audi at several fairs like the keel week followed by CES Las Vegas or the LA Autoshow and many more.
But for the founders it was clear from the beginning that the e-foil wasn’t just built to be presented on shows, to be available for everyone.

A Lineup Built for Every Rider

Adventure, Performance, Competition, Hyperfly, Airfly - a full family of eFoils, each crafted for a different rider and a different kind of water. Aerofoils growns from a single product into a complete and considered lineup.

The Next Chapter

Aerofoils joins the Rosenxt Group. A partnership that brings industrial-scale ambition, global reach, and a shared commitment to engineering excellence. A new chapter, built on everything that came before.
