Oshen make & deploy constellations of small, autonomous, rugged robots across the world's oceans. THE OCEAN'S NEXT SENSING LAYER Persistent, wide-area ocean intelligence for climate, security, and infrastructure. Talk to us We depend on an ocean we barely observe. The modern world depends on the ocean. Ninety percent of global trade moves by sea. Energy pipelines and data cables run across the seabed. Extreme weather systems form and intensify over open water. Yet most of the ocean remains poorly observed, with blind spots that expose governments and economies to growing risk. We built the arteries of the modern world on the ocean, yet monitor it less than the surface of distant planets. A changing world demands persistent ocean awareness. Today's ocean observing toolkit includes: Crewed patrols & ASVs Deliver high-fidelity observations for specific locations and missions. Drifting sensors Low-cost instruments that enable broad environmental sampling over large areas. Satellites Essential global coverage for some surface conditions and large-scale patterns. Our current ocean observing systems are highly capable, but they were designed for a world where persistence at scale was not feasible. Ocean activity, asymmetric threats, and extreme weather have all increased, while advances in autonomy and sensing have fundamentally changed what is possible. Just as small satellites transformed space and autonomous drones transformed the air, the ocean is ready for its next sensing layer. Oshen provides the ocean's next sensing layer. We do this by deploying constellations of autonomous, long-endurance micro ocean platforms known as C-Stars. Each C-Star is navigable, persistent, and designed to operate as part of a distributed network. Oshen C-Stars have logged sea miles to circumnavigate the globe multiple times, are already trusted by government agencies operating in high-risk environments, and are the world's only surface robots to enter and survive a category 5 hurricane. Trusted by governments and institutions operating in high-risk ocean environments

JOIN OSHEN We're building the ocean's next sensing layer. If that's the problem you want to work on, we'd like to meet you. View Open Roles WHY OSHEN When we build something, we deploy it. That proximity - between code, hardware, and the real world - is what makes Oshen different. You can find yourself optimising component designs in the workshop one moment, and out on a boat deploying our C-Stars the very next. All in a single morning. We work fast because we have to - the ocean doesn't wait and neither do we. When something breaks at sea, it gets figured out that week. That pace shapes who thrives here: people who want to own problems, not hand them off - and see their work on the water. OPPORTUNITIES AT OSHEN GENERAL ENGINEER A versatile engineer with a strong electrical bias, working across hardware, integration, and field deployments — from wingsails and sensors to navigation and sea trials.

UNLOCKING OCEAN INTELLIGENCE Persistent, wide-area ocean intelligence for climate, security, and infrastructure. Contact the Team THE OCEAN DATA GAP The data needed to forecast hurricanes, protect critical infrastructure, and detect undersea threats arrives sparse, late, or not at all. Oshen closes the gap with swarms of one-metre robots that sail themselves across oceans, hold station for months, and stream weather and acoustic intelligence in real time — built to deploy by the thousand. Limited Coverage Most ocean monitoring relies on costly, static buoys and crewed vessels, leaving massive gaps in ocean data. Delayed Data Critical environmental insights often arrive too late for fast decisions, creating an intelligence lag that costs millions in avoidable downtime. Growing Demand As offshore projects scale to ambitious levels, the current data supply chain has become a bottleneck for reliable environmental intelligence. CONSTELLATIONS:
 STRENGTH IN SCALE A single sensing platform provides valuable data. 
A constellation of platforms unlocks a completely new level of ocean intelligence. Start With One Platform Each C-Star platform operates as an autonomous sensing node, collecting high-quality metocean data directly from the ocean environment.

OUR MISSION We’ve built the modern world using the oceans as our arteries. Almost none of them are watched. A single undetected failure can leave the global economy defenseless. Oshen exists to close that intelligence gap: a wide-area, persistent monitoring network that is the eyes and ears across the seas, built to predict and catch what's failing before it becomes a crisis. Oshen's C-Stars have sailed through a Category 5 hurricane and streamed data the whole way. At one-metre-long, each robot sails itself across oceans, holds station for months, and reports back in real time. We design them to be deployed by the thousand. 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 what the ocean is doing. We're the only company that's made an ocean robot that's persistent, navigable, and scalable at once. Others go offline in days, go wherever the current takes them, or cost a million pounds each. For the people who operate at sea, a gap in your data isn't an inconvenience. We exist to close it. In just 2 years and £220k, we’ve built a technically dominant ocean sensing platform and signed major government bodies. This is what we’ve executed on a shoestring. Imagine our next step.
