Andrenam develops PEARL, a network of passive acoustic buoys, and OBSIDIAN, an AI-native software platform that converts underwater sound into real-time maritime awareness. The company positions its technology to provide persistent awareness of undersea activity as the domain becomes more contested and autonomous. Andrenam argues legacy systems are expensive, slow to field, and depend on a small pool of specialists, and aims to offer a more scalable solution. The recent Series A financing is intended to expand deployments and grow the team to meet rising demand. The announcement did not disclose revenue, users, or prior funding details.
