PierSight reports that it has raised additional capital in a new funding round to bring total capital raised to $8 million as it works toward launching a commercial constellation of Synthetic Aperture Radar (SAR) and AIS (VDES-enabled) satellites for maritime surveillance.
The investment round includes backing from Sustainable Ocean Alliance (SOA) and its venture arm, Seabird Ventures, as well as CE-Ventures, the corporate venture capital platform of Crescent Enterprises. A number of individual investors also took part.
PierSight aims to deliver continuous, all-weather maritime monitoring with a 30-minute revisit rate across the world’s oceans. The company launched its technology demonstration satellite, Varuna, in December 2024 and its first commercial SAR and AIS satellite is under development for a mid-2026 launch.
A maritime analytics platform, MATSYA, and a drone-based SAR system are both expected by the end of 2025, the company says.
PierSight is currently working with coast guards, insurers, port operators, shipping lines, and conservation groups to develop applications including EEZ monitoring, IUU fishing detection, oil spill tracking, dark vessel identification, and maritime insurance fraud.
“We have the necessary resources in place to reach our upcoming targets,” said Gaurav Seth, Co‑founder and CEO of PierSight.
“This round was about welcoming partners who bring frontline experience in ocean sustainability and port operations, and can help us build a world‑class team.”
