Neptune Robotics

The company's core offering is a fleet of semi-autonomous, remote-operated underwater robots designed to clean biofouling—such as slime, algae, and barnacles—from ship hulls. This accumulation increases drag, which can raise fuel consumption by an average of 15-18%. Neptune's technology utilizes a proprietary cavitational waterjet system that removes this organic matter without damaging the vessel's anti-fouling paint. A key operational advantage is the robots' ability to function both above and below the waterline and in strong currents of up to four knots, enabling 24-hour service at ports and anchorages. The system is also equipped to operate in murky waters where visibility is zero by using an AI-backed operating system and pre-loaded hull form data to advise the remote operator.

Financially, Neptune Robotics has secured significant investor support, raising a total of $17.4 million over three funding rounds. A pivotal Series A round in April 2022 brought in $17.2 million, led by investors including Sequoia China, HSG, Matrix Partners China, and SOSV. This capital is being used to expand its service network, invest in product development, and hire additional engineering talent and marine biologists. Since beginning commercial operations in 2020, the company has expanded its presence to over 60 ports, primarily along China's coastline and recently in Singapore, serving major clients like Cargill. The collected biofouling is taken ashore for proper disposal, aligning with environmental regulations.
