The details

  • PierSight Space is an Ahmedabad-based startup building compact radar satellites to monitor the world's oceans, even through clouds, darkness, and adverse weather.
  • The company raised one of the largest seed rounds in India's space-tech sector, though the exact amount remains undisclosed.
  • Founded by Gaurav Seth, a former ISRO scientist, the startup aims to address the blind spots in maritime trade and security.
  • PierSight's satellites use synthetic aperture radar (SAR) technology, which allows them to image the oceans regardless of weather or time of day.
  • The technology is designed to solve commercial and strategic problems on Earth, not just explore distant planets.
  • The company has already attracted attention from investors and defence organisations, including joint challenges backed by India and the United States.

The bigger picture

  • The ocean is the largest blind spot on Earth, with many ships disappearing from view once they leave the coastline.
  • Traditional satellites rely on sunlight, which limits their visibility in cloudy, stormy, or dark conditions.
  • Radar satellites like those built by PierSight can create their own light, making them more reliable for continuous monitoring.
  • The shift from scientific exploration to commercial and strategic applications has made PierSight's technology highly relevant.
  • India is emerging as a key player in deep-tech innovation, and PierSight is part of this growing ecosystem.

About the business

  • PierSight Space builds compact radar satellites that can monitor the world's oceans continuously, regardless of weather or time of day.
  • The company's synthetic aperture radar (SAR) technology allows it to see through clouds, darkness, and adverse weather.
  • Its satellites are designed to solve commercial and strategic problems on Earth, such as maritime surveillance and security.
  • The startup has already won joint defence challenges backed by both India and the United States.
  • PierSight's technology could be used to track illegal fishing, smuggling, and other maritime activities that are currently difficult to monitor.
