Maker of Underwater Robots Snags $52 Million for Global Push

Neptune Robotics, which makes robots that clean the underside of giant ships, raised $52 million to accelerate its artificial intelligence-fueled global expansion.

The funding round is a step toward a planned initial public offering in the US as soon as 2027, Chief Executive Officer Elizabeth Chan said in an interview. It will help the Singapore-based company expand its reach to as many as 30 countries as it targets the world’s biggest container-ship fleets.
