Top Maritime, Ocean And Aquaculture Tech Startups In Norway To Watch In 2027

Norway has a long coastline, a lot of salmon and a habit of turning both into technology. Add decades of shipping and offshore experience, and you get one of the most interesting ocean tech scenes in the world.

Working farms, busy shipping lanes and offshore sites are all within reach of the coast, so teams can test their ideas in real conditions instead of a lab. It also means the people building these products have often grown up around the industries they’re trying to improve. The result is a crop of startups tackling practical marine challenges head-on, including self-driving ferries, kelp farms, net-cleaning robots and sea freight marketplaces.

What Makes Norway’s Coast Such Good Ground For Startups?

Data from the Norwegian Seafood Council shows the country shipped 1.4 million tonnes of salmon in 2025, valued at NOK 124.7 billion (roughly £9.1 billion). Operating at that large scale means fish farmers are locked in a daily battle with sea lice, stock welfare and the gruelling costs of operating in freezing, remote fjords.

This all creates demand for tools that save time, money and manual labour, which is why so many of these startups sell to working farms and ships rather than consumers. Plenty focus on automation, data and cleaner operations, and a number are backed by industry investors such as Grieg Kapital and Hatch Blue.

The Top Maritime, Ocean And Aquaculture Tech Startups In Norway

With the sector growing, more startups are setting up along the Norwegian coast. Here’s a list of the ones to watch in 2027:

Remora Robotics

Stavanger-based Remora Robotics builds clever underwater robots that clean fish farm nets while keeping tabs on fish health simultaneously. Cutting down on manual scrub-downs means less reliance on divers and support boats, a huge win for farmers eager to trim operating costs.

Investors took notice in July 2025, when Remora bagged NOK 164 million (about €15 million) in funding from Singularity, Grieg Kapital and new backer Hatch Blue. The company says the money will help it meet increased demand from major aquaculture producers.

Biosort

Biosort, from Oslo, uses machine vision and AI to identify individual fish and spot sea lice, lesions and disease early, so treatment can be targeted inside the sea cage. Sea lice are one of salmon farming’s costliest problems, so the appeal is obvious.

The company raised more than NOK 100 million in February 2026 from investors including Grieg Kapital and Hatch Blue. The funding is meant to finish development and bring its next-generation lice-control system to market. The aim is to remove lice continuously in the pen and cut reliance on wellboat treatments.

Aquabyte

Aquabyte helps salmon farmers make smarter decisions by combining high-res subsea cameras with intelligent software that tracks sea lice counts, fish growth and general stock health.

Running operations from both Bergen and San Francisco, the startup charges for its platform through a subscription fee. With total investment clearing $46 million, it’s among the most well-capitalised names in marine tech. Selling decision-support software instead of hardware alone gives it an edge over many other robotics companies. Farmers get continuous insight into fish and environmental conditions.

EasyX

EasyX, based in Bergen, builds wall-climbing robots that clean aquaculture tanks, gripping slick surfaces with vacuum technology and high-friction belts.

The idea began in 2020, when two neighbours got frustrated with house painting during lockdown, before the team switched its focus to fish farming. The first units were delivered to Mowi, one of the world’s biggest salmon producers, in April 2025. Before the full prototype was even finished, the team used animation to show the concept to industry leaders, which helped win early interest. It was targeting 50 contracts for the year.

Water AS

Water AS is tackling environmental impact across the salmon supply chain, providing water treatment systems for wellboat delousing and slaughterhouse wastewater management.

Launched in Stavanger in 2023, the startup has already executed over 100 commercial operations and secured NOK 15 million in September 2026 seed funding to drive its next phase of growth. Its wastewater work is designed to meet new best-available-technology discharge requirements. It may be less eye-catching than the AI camera companies, but it deals with a practical problem: what happens to the water after lice treatment and processing.

Zeabuz

Trondheim startup Zeabuz creates intelligent control software that handles a ferry’s acceleration, steering and terminal docking without human intervention.

Announced in October 2025, the team is supplying key self-navigating systems to convert Swedish road ferry Neptunus into a battery-hybrid vessel, forming part of a SEK 97 million upgrade project. Its system also helps optimise battery use. The ferry will run on the Gullmarsleden route in Bohuslän.

Keelspot

Keelspot, founded in 2022 by Svein Arild Vatsø, runs an online freight marketplace that aims to fill empty space on coastal ships and make shipping goods by sea simpler.

It had pilot customers in Norway, Finland, Turkey and the Netherlands, and was reported in 2024 to be seeking NOK 25 million for expansion. It received NOK 4.7 million from Innovation Norway and NOK 6 million in initial investment. The idea is simple: make better use of ships that would otherwise sail partly empty.

Kelpinor

Kelpinor’s first major production site is at Vedkjæran in Gildeskål, where its kelp rig covers 50,000 square metres.

The northern Norwegian team is aiming high, targeting 10 million tonnes of seaweed output within a decade to cement its spot in the sustainable ocean economy. Kelpinor describes itself as a growing sustainable aquaculture startup. It says it wants to scale output in Norway and globally.

Havguard

Havguard, founded in 2023 and based in Leknes, develops distributed intelligence systems for detecting maritime threats in real time.

Company listings describe it as a defence technology company, which fits a world where autonomous vessels and offshore infrastructure are becoming more common. Its stated mission is to create clarity in challenging maritime environments. It’s led by CEO and co-founder Emilie Åsberg alongside co-founder and CFO Håvard Lillebo.
