Oshen builds the C-Star: a one-metre robot that sails itself across oceans, holds station for months, and reports back in real time. We design them to be deployed by the thousand. Watching an ocean takes a fleet, not a flagship.

We're the only company that's made an ocean robot that's persistent, navigable, and scalable at once. Large autonomous surface vessels work but cost a million pounds each. Drifting buoys are cheap but go wherever the current takes them. Battery-powered drones can navigate but die in days. C-Stars do all three, at low cost, at scale.

C-Stars have sailed through a Category 5 hurricanes and streamed data the whole way. A swarm can watch a wind farm, a shipping lane, or a chokepoint, turning blank spots on the map into a real-time view of weather, sea state, and what moves beneath the surface.
