Paddle in
Get into position on the wave and paddle hard to catch it.
Practise catching a wave and getting to your feet on a surf simulator. More chances to prepare for your next session in the ocean.
In the ocean, you wait for the next wave. On DropIn, you practise the take-off again and again: the seconds that decide the ride.
Your wave. Your time. Your pace.
Make mistakes, repeat an attempt and work at your own pace.
Be among the first to rideDeveloped through five years of research at USC, the working prototype brings a real board and a responsive motion platform together. We’re now preparing for early riding sessions. The film shows the intended DropIn experience, including coaching in development.
“I am now an intermediate surfer and basically learnt surfing on the simulator in a few weeks.”
Get into position on the wave and paddle hard to catch it.
Feel the tail lift as the board starts to move, then pop up to your feet.
Drop down the face and shift your weight to carve along the wall.

DropIn captures each take-off and ride, from your last paddle strokes to your first turn.
In the ocean, you rarely know why a take-off failed. DropIn shows you what to adjust while the last attempt is still fresh.
Track how your take-off improves across sessions, and get your next focus based on how you actually surf.

Between surf trips, there’s a lot of life. We’re building a way to keep surfing part of it.

A surfer who knows how hard it is to progress between trips. Lisa has worked for a decade across strategy consulting and commodity trading in wave-deprived cities like Zurich, London and Hong Kong — and has a PhD as an economist from ETH Zurich. She founded DropIn to turn university-developed surf simulation technology into a training experience that helps more people find their feet on a wave.
