The ocean is a chaotic system, and the captain's bridge is a place of constant, high-stakes judgment. For a vessel operator, the difference between a profitable quarter and a loss-making one can be a few percentage points of fuel saved, or the avoidance of a single hull-damaging wave. Hefring Marine, a six-year-old company out of Reykjavik, is betting that the right real-time data can turn that judgment from an art into a repeatable, optimizable science.
Its wedge is a piece of onboard hardware and software called the Intelligent Marine Assistance System (IMAS). It ingests sensor data on vessel motion, navigation, and operational conditions, then provides crews with continuous guidance on throttle and heading. The promise is straightforward: sail more efficiently, avoid damaging impacts, and bring down the cost of insurance. The company claims its system is already tracking over 1,000 vessel trips per month across a database of professional operators [Hefring Marine, May 2024].
The onboard wedge into defense and commercial fleets
Hefring's approach is pragmatic. It is not selling fully autonomous vessels, a capital-intensive and regulatory-heavy proposition. Instead, IMAS is a layer of decision support that sits on top of existing vessel infrastructure. The system processes real-time data to suggest micro-adjustments, aiming to keep a ship on the most efficient and safest path given sea conditions [SeaBot Maritime and Hefring Marine, retrieved 2026].
The company's newer product, ODIN (Observation and Domain Awareness Network), extends this logic into networked intelligence, connecting navigation and object-detection data across multiple vessels. This is the product that caught the attention of NATO's Defense Innovation Accelerator for the North Atlantic (DIANA). In 2026, Hefring was selected for the DIANA cohort from over 3,600 applicants and later advanced to the more selective Mission Track [Ocean News, Sep 2026]. That move signals a strategic push into the defense and security sector, where domain awareness is a critical capability.
The traction and the claimed economics
For a seed-stage company, Hefring articulates a clear value proposition tied to hard operational costs. Its publicly stated metrics, while self-reported, are the kind that resonate with a fleet manager's spreadsheet. The company says IMAS can help customers achieve reductions in three key areas:
- Fuel and emissions. Up to a 20% cut in fuel consumption and corresponding CO2 output [Hefring Marine, retrieved 2026].
- Vessel wear. Up to an 87% reduction in harmful wave slamming impacts [Hefring Marine, retrieved 2026].
- Insurance costs. As much as a 20% savings on premiums by demonstrating safer operations [Hefring Marine, retrieved 2026].
These claims form the core of the sales pitch. A 20% fuel saving directly improves margins, while the reduction in hull slamming extends asset life and lowers maintenance. The insurance angle is particularly clever, as it turns a safety product into a financial instrument, potentially shortening the procurement cycle by aligning with the risk manager's budget.
The team and the €2.2 million seed round
The founding team brings a blend of technical and operational maritime experience from Iceland's seafaring culture. CEO Karl Birgir Björnsson oversees strategy and IMAS development, while co-founder Björn Jónsson serves as Chairman and COO [Perplexity Sonar Pro Brief, retrieved 2026]. A third co-founder, Magnús Þór Jónsson, is listed as CSO. Notably, Björn Jónsson has a separate public profile as an astronomical artist whose work has been featured by NASA, a background that hints at a strong aptitude for data visualization [Forbes, 2019].
In May 2024, the company closed a €2.2 million (approximately $2.39 million) seed round led by Faber Ventures. The syndicate included a mix of European maritime and deep-tech focused funds like Innoport VC, Two Ravens, and Riverstone Ventures [Perplexity Sonar Pro Brief, May 2024].

Where the pitch meets procurement reality
The risks here are classic for a hardware-enabled SaaS play selling into traditional industries. First, the sales cycle for onboard systems in defense, search and rescue, and commercial fleets is long and relationship-driven. Hefring has named customers like the Norwegian Sea Rescue Society and VIKING Norsafe, but the path to scaling deployments across entire fleets is unproven. Second, while the performance metrics are compelling, they require third-party validation to become a standard part of the procurement checklist. A fleet operator will want to see those fuel savings verified on their own vessels over multiple quarters before committing to a fleet-wide rollout.
The company's answer appears to be a dual-track approach. The NATO DIANA Mission Track provides not just validation but also up to €300,000 in non-dilutive funding and access to test centers, which can de-risk the product for other government buyers [Ocean News, Sep 2026]. On the commercial side, the insurance premium reduction is a powerful lever to pull, potentially aligning the product with a different and more financially-minded buyer inside a shipping company.
The next twelve months
The immediate focus will be on converting the DIANA advancement into tangible pilot programs and, ultimately, paid contracts within the defense ecosystem. Success there would provide a powerful reference case for commercial fleets that prioritize security and resilience. Concurrently, the company needs to expand its footprint within its existing commercial segments,search and rescue, fisheries, pilotage,and start reporting contract sizes and renewal rates. The head of sales role, filled by Michael Given, will be critical in this phase [Hefring Marine, retrieved 2026].
Hefring's ideal customer profile is not the owner of a single yacht, but the technical operations manager for a fleet of 20 to 200 professional vessels, where small efficiency gains compound across the asset base. The realistic competitive set includes companies like Maritime Robotics and Sea Machines Robotics, which focus more on vessel autonomy, and software-centric players like ZeroNorth, which optimize voyage planning from shore. Hefring's distinction is its insistence on being onboard, providing real-time guidance at the point of decision, rather than offering a pre-voyage plan that becomes obsolete in changing seas.
