Anahita Laverack and Ciaran Dowds founded Oshen in April 2022 after meeting at Imperial College London. Their engineering and sailing experience shaped its focus on observing waters that are difficult or costly to monitor with crewed vessels. Plymouth provides access to on-water testing, Marine suppliers and engineering talent. Applications include offshore operations, environmental monitoring and infrastructure security, where repeated observations can support planning and help operators understand changing conditions.
