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

OUR MISSION Powered by the sun and driven by the wind. Our C-Stars are mass-deployable, navigable ocean sensors essential to understanding climate dynamics, protecting critical infrastructure, and operating safely at sea. 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.

Meet the team and learn about how the idea and vision for Oshen began Our Mission Our mission is to build a persistent sensing layer for the world’s oceans. Oshen develops autonomous systems that can be deployed at scale to continuously monitor the ocean surface and near-surface environment. We believe that mass-deployed, navigable ocean sensors are essential to understanding climate dynamics, protecting critical infrastructure, and operating safely at sea. Founders Anahita Laverack CEO Background: Holding a degree in Aeronautical Engineering from Imperial College London, Anahita completed her Master's in the design and navigation of transatlantic autonomous micro-vessels. Prior to co-founding Oshen, she worked as a robotics engineer at start-up KinKeepers. Present day: Anahita currently oversees Oshen's strategic development and hardware design, applying her specialised knowledge to advance autonomous marine sensing technologies. Fun fact: A keen sailor, Anahita maintains that an underlying motivation for providing ocean data for better forecasts was born in 2020, after having to double-handed sail continuously for 3 days to try outrun a poorly forecast storm. Ciaran Dowds CTO Background: Ciaran holds an MEng (Hons) in Electrical and Electronics Engineering from Imperial College London, where he earned a place on the Dean's List for his academic achievements. Before Oshen, Ciaran developed an app used by NHS speech therapists for children, and workedat DSTL. Present day: As CTO and co-founder, Ciaran leads on further improvements across all areas of Oshen's R&D, as well as developing the main autonomous control system for the platforms. Fun fact: After recovering an Oshen platform from the Irish Sea, despite being a recent convert to sailing, Ciaran solo sailed the 25ft sailboat through a force 5 back to their home port. Advisors Brett Phaneuf Brett is the founder and chief executive of Submergence Group (USA) / MSubs (UK), specialising in robust, manned and unmanned ocean-going systems. A serial entrepreneur, Brett recently lead the development of the Mayflower Autonomous Ship - a 50ft AI powered vessel that crossed the Atlantic in June 2022. Wayne Pavalko Founder WRG, Inventor of the MakerBuoy. Driven by a fascination with the Internet of Things applied to the ocean, Wayne pioneered the MakerBuoy - an open source, low cost drifter. From Atlantic crossings to tracking ocean plastic, Wayne’s creations have survived the harshest of ocean environments, often for 600+ days. Dr Peter Smout An Associate Fellow at Rolls Royce, Peter has over 30 years experience in technical engineering challenges, and has contributed to several patents ranging from composite fan blades to a novel method of operating a heat exchanger assembly for a gas turbine engine. Arthur Richier Head of Partnerships, strategy and sustainability at Vortexa, a leading energy and shipping AI analytics scale-up, and has featured in Bloomberg, Al Jazeera, The Moscow Times and The Houston Chronicle. His specialist interest in machine learning extends to start-up funding across logistics and insurance. Timeline We’re a company with an ambitious mission to deploy a large-scale constellation of robots across our oceans. However, we don't want to over-hype our capabilities, or overstate where we're at. The ocean's next sensing layer requires 1000+ C-Stars to make the biggest impact possible. Individual C-Stars have completed 4+ month msisions, collected data in hurricanes, but constellations are in the 10s, not hundreds. Below, we’ve shared a little about our journey so far, and what you can expect from us in the future. Founders begin work designing small wind-powered ocean robots, inspired by the Microtransat challenge. 2021 2022 First C-Star built and tested in conditions up to Beaufort force six. Oshen awarded funding from the European Space Agency. Begin DEFRA funded project assessing using C-Stars for biodiversity monitoring. 2023 C-Stars are reliably completing 24hr fully autonomous unsupervised missions at sea, fitted with Met-Ocean and Passive Acoustic Monitoring sensors. The Guardian, BBC news and The Times feature exclusive features on Oshen. C-Stars are used for a successful passive acoustic data collection exercise in Cardigan Bay. 2024 C-Star leased under the Synchro program by MBARI, deployed on four missions in Monterey Bay (USA). Batch manufacture run expands the fleet to nine C-Stars A C-Star operates in a winter storm with 9m high waves, reliably transmitting weather data throughout. Oshen provides the storm data to The Met Office for research & development. 2025 Oshen are awarded a £2m project funded by the Advanced Research + Inventions Agency (ARIA) to design & deploy a 50-strong C-Star constellation in the North Atlantic to predict climate tipping points. Oshen C-Stars become the world's first surface robots to collect data in a category 5 hurricane while completing a project with 8 C-Stars for NOAA.
