Syrenna has developed the WaterDrone, a sealed robotic platform that controls its depth with a swim-bladder and maintains geographic position via a proprietary tether to provide persistent, near–real-time subsea sensing. The device carries sensors for temperature, salinity, microplastics and other marine metrics, runs on a battery rated for a full year of operation, and is being developed to recharge at the surface and transmit data via Iridium satellites. Syrenna completed a next-generation hardware version and has run pilots in Oslofjord and offshore tests to 180 meters, with longer-term trials underway. The company plans to sell robots directly to customers and to release some collected data publicly through partners such as Hub Ocean. Operating since 2022 out of Oslo, Syrenna has been engineering‑centric in hiring and is now expanding toward productization and full‑stack developer hiring to improve visualizations and BI integration.
