Spear AI, a startup founded by two U.S. Navy veterans, has secured $2.3 million in seed funding and a $6 million contract from the U.S. Navy. The company aims to revolutionize underwater surveillance using artificial intelligence. Michael Hunter, a former Navy SEAL analyst, and John McGunnigle, a retired nuclear submarine commander, launched Spear AI in 2021.
The Washington-based company specializes in interpreting passive acoustic data, which is underwater sound collected by hydrophones and other listening devices. Underwater acoustic data is mostly unstructured and unlabeled, making it challenging for traditional AI systems to analyze. Spear AI’s solution includes deployable sensors that can be attached to buoys or vessels, along with AI-driven software that labels and organizes the data.
This enables advanced machine learning models to extract actionable intelligence from the ocean of noise. The $6 million Navy contract focuses on deploying Spear AI’s data-labeling tool, designed to support more accurate threat classification and improve response times to evolving underwater risks. This capability is critical as rival powers increase submarine deployments, and information asymmetry under the sea remains a major vulnerability for naval forces.
Securing underwater intelligence with AI
The $2.3 million seed funding round was backed by venture capital firms focused on artificial intelligence and national defense technologies. The capital will fuel the company’s growth, including a planned expansion of its 40-person workforce, which the founders say will double in the coming months.
Beyond military use, Spear AI is exploring commercial applications, such as monitoring undersea infrastructure like oil pipelines and subsea internet cables. The startup also plans to offer consulting services, helping clients embed AI capabilities into their operations, particularly in complex, high-risk environments where accuracy and reliability are critical. However, the growing use of AI in warfare capabilities has raised concerns about an AI arms race.
The U.S. has expressed concerns about China’s potential in developing super military technologies powered by AI, prompting restrictions on some chip exports to China. Chinese Premier Li Qiang warned that artificial intelligence development must be weighed against security risks, emphasizing the need for global consensus. As global tensions rise and the Pentagon pushes to modernize its forces, startups like Spear AI are expected to play a growing role in reshaping 21st-century defense strategies.
The company’s AI-first approach could redefine how threats are detected and neutralized in domains like undersea warfare, where surveillance has historically lagged due to technical limitations. With the support of their recent funding and the Navy contract, Spear AI is poised to make significant strides in enhancing underwater surveillance, presenting new possibilities for both military and civilian applications.
