- Copenhagen-based Triton Depth, founded in 2025 by three DTU engineering students, has raised €1 million in pre-seed funding
- It aims to address one of the EU’s most underserved security concerns: the seabed, as Baltic cable sabotage, shadow-fleet activity, and underwater drone warfare are increasingly growing concerns
- Triton Depth intends to build a scalable network of passive acoustic sensors it calls ‘Triton Nodes’ to address the issue, leveraging AI to identify vessels and objects in real time
A three-man Danish company founded by students is venturing into a somewhat interesting industry for an EU-based startup: underwater defense.
Triton Depth has received €1 million in pre-seed funding from investors including London-based The Creator Fund and Denmark’s state-owned Export and Investment Fund (EIFO), with aims to focus on acoustics to answer what is arguably Europe’s biggest security threat in the days to come: drone-based naval warfare and sabotage.
With growing concerns about the vulnerability of the European Union, and by extension, Denmark, to a variety of sea-borne threats, EIFO’s investment in Triton Depth might be more than just a value play, but a hallmark of a realization that it needs to tend to its own defense needs even as NATO continues to meander, with the US proving to be a volatile partner of late, to say the least.
Using affordable dual-use acoustic technology as the first line of defense
Triton Depth’s approach is appealing for a domestic defense industry that does not share the budgets that larger naval players such as the US, Russia, or China possess: it is simple, yet elegant in its premise, and even partial wins when it comes to its claims would go a long way to safeguard Denmark and the EU’s regional interests.
Triton Depth’s approach centers around the use and deployment of its ‘Triton Nodes’, a scalable cluster of low-maintenance passive acoustic sensors that measure sound underwater before feeding information back to an AI model that assesses and classifies signatures it detects in real time.
The company intends to market its product line as a dual-use technology play, with CEO and Co-Founder Carl Borg stating that they aim to build “the intelligence layer for the ocean” for both civilian and defense use cases.
The focus on defense stems from Denmark’s own vulnerabilities in the Baltic Sea, which has previously suffered significant economic damage from sabotage, including the destruction of Nord Stream 1 and 2.
With an increasing share of its critical infrastructure, including power interconnectors, data cables, and offshore wind, lying underwater, it could be argued that EIFO’s investment is the Danish state safeguarding its own maritime security and intelligence interests by investing in an intelligent tripwire for the future.
Other European governments are also actively seeking scalable, affordable ways to monitor coastal and subsea infrastructure, even as Nordic defense budgets continue to rise, with Triton Depth among many defense infrastructure companies poised to benefit from a renewed focus on maritime security in the region, even as acoustics are seen as a reliable metric to monitor for a variety of infrastructure plays.
