Spear AI
Spear AI is a Washington, D.C. defense-technology company founded by U.S. Navy veterans that turns raw underwater acoustic data into decision advantage for maritime and undersea operations. It pairs affordable, deployable maritime sensors with AI/ML software - anchored by its Horizon platform for managing and labeling acoustic data - so naval leaders can tell a benign whale from a silent-running submarine faster and with more confidence. The company also provides engineering and technical services to the U.S. Department of Defense and Navy.
