Danish Startup Triton Depth Secures €1 Million to Bolster Underwater Security

Strengthening Europe’s Subsea Defense

Copenhagen-based startup Triton Depth, established in 2025 by a trio of engineering students from DTU, has successfully closed a €1 million pre-seed funding round. The company is entering the specialized field of underwater defense, a sector gaining critical importance as the European Union faces mounting security challenges at sea.

The funding, supported by investors including The Creator Fund and the Danish state-owned Export and Investment Fund (EIFO), will be used to develop a scalable network of passive acoustic sensors designed to mitigate threats such as sabotage, the activity of shadow fleets, and the emergence of underwater drone warfare.

The 'Triton Nodes' Technology

The core of the company’s strategy involves the deployment of 'Triton Nodes'. These are low-maintenance acoustic sensors that monitor underwater soundscapes. The gathered data is then processed by an artificial intelligence model capable of identifying and classifying maritime objects and vessels in real time.

Carl Borg, CEO and Co-Founder of Triton Depth, describes the project as an effort to create “the intelligence layer for the ocean,” which the company intends to market as a dual-use technology suitable for both civilian and defense applications.

Addressing Regional Vulnerabilities

The focus on defensive applications is largely driven by Denmark's specific vulnerabilities within the Baltic Sea. The region has previously experienced major economic repercussions from acts of sabotage, most notably the destruction of the Nord Stream pipelines. With critical infrastructure—including data cables, power grids, and offshore wind farms—increasingly located on the seabed, the need for robust monitoring has become a national priority.

As European nations seek cost-effective and scalable methods to protect their maritime assets, Triton Depth is positioning itself as a vital player in the defense infrastructure market. By providing an intelligent monitoring system, the startup aims to help Denmark and the broader EU safeguard their interests against evolving subsea threats.
