Oshen Raises $5M to Scale Hurricane-Tested Ocean Robots

Oshen is a UK startup using C-Star robots to collect ocean data in harsh conditions. Its $5 million funding round supports manufacturing for systems supplying climate, maritime, and defense information.

Revolutionizing Ocean Data Collection

Founded in April 2022 by Imperial College London graduates Anahita Laverack and Ciaran Dowds, Oshen builds ocean-sensing technology. The company's C-Star robots are 1.2-metre autonomous surface vehicles powered by wind and solar energy. These robots are light enough for a single person to deploy from a boat and can operate autonomously for months, transmitting data via satellite. This capability allows them to cover vast oceanic distances, either spreading out or clustering as needed, making them valuable for persistent distributed ocean sensing.

Funding and Expansion

Oshen's recent $5 million funding round, led by Lunar Ventures with participation from AlbionVC, Twin Track, Concept Ventures, and angel investors, marks a significant milestone for the company. According to Tech Funding News, this investment will enable Oshen to scale its manufacturing operations in Plymouth, where the company has grown from seven employees in September 2025 to nearly 30. The company is now producing 15 C-Star robots every six weeks, a significant increase from its initial production rate.

Impact on Climate and Maritime Operations

Oshen's C-Star robots have already demonstrated their value in extreme conditions, becoming the first uncrewed vehicles to transmit real data from inside a Category 5 hurricane, as reported by NOAA. This capability is crucial for improving climate models and understanding the dynamics of severe weather events. The data collected by these robots can also enhance maritime operations, providing real-time insights into ocean conditions that are vital for navigation and safety.

Strategic Importance for Defense and Energy

The unmanned surface vehicle market is projected to grow significantly, with defense spending expected to be a major driver, according to a MarketsandMarkets estimate. Oshen's technology is well-positioned to capitalize on this trend, offering strategic advantages for defense operations through enhanced surveillance and data collection capabilities. Additionally, the energy sector can benefit from the detailed environmental data provided by these robots, aiding in the exploration and monitoring of offshore resources.
