Triton Depth builds acoustic intelligence for the seabed. The ocean is the last unmonitored domain. Ninety percent of global trade moves across it, and the cables, pipelines, and wind farms that Europe runs on sit in water nobody is listening to. The threats are no longer hypothetical. Nord Stream, the Baltic cable cuts, repeated incursions around critical infrastructure. The gap between what operators can see above water and what is actually happening below it has become impossible to ignore. We are closing that gap. Our sensors sit on the seabed, listen continuously, and classify what moves through the water on-device. Divers, autonomous underwater vehicles, vessels behaving in ways they should not. Nodes form a wireless acoustic mesh and relay alerts to a surface gateway in real time, with a detection radius of roughly 8 km per node. The result is persistent underwater awareness at a fraction of the cost of legacy sonar systems, deployable in days rather than years. We serve port operators protecting critical infrastructure, defence integrators building the next generation of maritime surveillance, and allied operations where seabed awareness is now a frontline concern. Early customers include a major Scandinavian port, a Tier-1 Danish defence integrator, and an EU sensor fusion project supporting Ukraine. Triton Depth was founded in 2025 at DTU by three engineers with backgrounds in AI, signal processing, and offshore operations. We are backed by the Danish Maritime Fund and Innofounder, and are members of MADE, Defence Tech Denmark, and CenSec. The seabed is the next domain. We intend to own the listening layer.
