Maritime Tech: Why the Industry That Moves 90% of World Trade Is Only Now Getting Its Software Moment
In our supply chain series (part I on technology as an enabler & part II on AI), we looked at how data, generative AI and cloud infrastructure are converging to reshape the software that moves goods around the world. Most of that conversation happens on land: warehouses, trucks, procurement teams, planning systems. But the vast majority of physical trade, around 90% by volume, spends most of its journey on a ship. And shipping is, by some distance, the least digitised part of the chain. It is also one of the more significant contributors to global emissions: international shipping accounts for roughly 3% of global CO₂, a share the sector has committed to cut to net zero by 2050.
That is not for lack of trying. Maritime software has existed for decades. What has changed is that the reasons it never scaled are falling away at the same time, and an industry that has run on email, PDFs and voice calls is finally getting the tools other sectors take for granted. This post is about why now, what is being built, and what it means for the way global trade operates.
Why shipping resisted software for so long
It helps to start with the structure of the industry, because the structure explains everything that follows.
Shipping is fragmented. There are more than 90,000 commercial vessels in the world, owned and operated by thousands of companies, most of them small. A ship is also a genuinely hostile environment for software: it spends weeks at sea with patchy, expensive connectivity, so data collected on board tends to stay on board. Every vessel is different in type, age and equipment, which makes standardisation hard. And the whole system sits under a safety regime in which class societies and flag states must sign off on anything that touches operations, so change is slow by design.
On top of that, the incentives are split. The owner of a ship, the charterer who hires it and the technical manager who runs it are often three different companies. Nobody fully owns the fuel bill, and fuel is more than half the cost of a voyage. Software that promised efficiency gains struggled to find a buyer who both paid for it and benefited from it. Add the fact that emissions at sea were, until recently, entirely unpriced, and you have an industry where the return on digital tools was structurally weak.
None of this was a technology problem. It was a plumbing, incentive and economics problem. And all three are now shifting.
Three forces opening the window
At Blume, we see three forces converging to change the picture:
Connectivity. Low-earth-orbit broadband, and Starlink Maritime in particular, has made always-on ship-to-shore data the norm rather than the exception. This sounds mundane but it is the single biggest unlock. Fleet-wide, real-time software was simply not possible when the ship went dark for days at a time. Now the on-board silo is dissolving and the vessel becomes a node on the network like any other asset.
Regulation. The EU Emissions Trading System now covers shipping in full, FuelEU Maritime has been live since 2025, and the IMO’s global net-zero framework brings measures from 2028. For the first time, carbon at sea has a hard price. That does two things. It creates budget where there was none, because compliance is mandatory. And it forces owners, charterers and managers to share an emissions P&L, which finally aligns the incentives that kept efficiency software on the shelf. The rules are still volatile, but the direction is not.
AI. The day-to-day work of shipping is remarkably text-heavy. Fixtures are negotiated over email. Port agents raise invoices as PDFs. Charter parties, bills of lading, inspection reports and crew documents are unstructured and multi-party. This is exactly the kind of work that language models are good at, and it is why maritime is turning out to be one of the more natural homes for agentic software.
Together, these give the industry the connection, the reason and the tools at the same time. The plumbing is finally in place.
A smaller market, but under-penetrated and accelerating
Maritime software is roughly a US$8 billion market today, growing at 10 to 14% a year(1). That is small next to industrial or supply chain software, and it is fragmented: no vendor owns the ship, and the top ten players hold well under half the market. But growth is uneven in an interesting way. The largest, most mature segments (ship management, ports and terminals, chartering) are growing high single digits to low teens. The newest ones, emissions and compliance, vessel data and autonomy, are growing 15 to 30% from a small base. The money is following the new catalysts, not the legacy ones.
The market is also consolidating fast. Data players are rolling up vessel-tracking and trade intelligence assets into platforms. The dominant chartering and voyage management vendor has become a serial acquirer. Class societies and marine OEMs, once purely certification bodies and equipment makers, are now among the most active buyers of software. Private equity has noticed too, with a string of platform deals across the last five years. For a sector that was largely ignored by institutional capital until recently, that is a meaningful shift.
Breaking down what is being built
We think about maritime software in two loosely connected halves. The first is the technical life of the vessel: design it, build it, keep it running, keep it compliant. The second is the commercial life of the cargo: fix it, move it, call at port, get paid. Each has its own buyers, maturity and dynamics.
The technical side: from on-prem systems to the connected vessel
Ship management software, planned maintenance, crewing and technical operations are the largest and oldest part of the market. These are long-lived, on-premise systems sold to owners and managers, deeply embedded and very sticky. The first wave here was digitising paper: maintenance schedules, crew records, procurement. The second wave moved those systems to the cloud, slowly, and largely under the control of incumbents.
What is new is the data now flowing off the ship. Connectivity means performance monitoring can happen continuously rather than from a noon report. Hull condition, engine health and fuel consumption can be observed in near real time and compared across a fleet. Inspection, once a clipboard exercise, is becoming a data product. Predictive maintenance, digital twins and hardware-free performance monitoring are moving from pilot to production. And compliance, which barely existed as a software category three years ago, is now a genuine product line: measuring, reporting and optimising emissions across EU ETS, FuelEU and IMO requirements.
The commercial side: from email to agents
Chartering, freight trading, voyage optimisation and port operations are more cloud- and data-native, more greenfield, and the earliest adopters of AI. The buyers here are charterers, operators, brokers and traders, whose economics depend on the speed and quality of decisions.
The evolution mirrors what we saw in supply chain. The first wave was information: vessel tracking, freight benchmarks, trade flows. The second was workflow: chartering systems, voyage P&L, weather routing that told you what to do. Now we are entering a third wave where the system does it. Agents that read the inbound cargo enquiry, match it against positions and draft the fixture. Agents that validate every line of a port call invoice against tariffs and history. Routing that reoptimises continuously against weather, fuel price and the carbon cost of the voyage. The shift is from “here is a recommendation” to “I have already handled it.”
Voyage and fuel efficiency deserves a specific mention. Because fuel is the majority of voyage cost, weather routing, trim and speed optimisation and bunker management deliver hard, measurable ROI regardless of regulation. Carbon pricing just makes the case stronger. This is the rare corner of maritime software where the return was always there; what was missing was the data to prove it and a buyer with aligned incentives.
The layer underneath: data becomes the moat
Binding both halves is the data and connectivity layer. As connectivity commoditises, the question becomes who owns the operational data that flows across it. Vessel positions, fuel curves, port cost histories, inspection findings and chartering outcomes are the raw material for every agent and model that follows. The companies assembling proprietary operational data, earning the trust of class societies and integrating deeply into existing systems are building defensibility that a nicer user interface never could.
What we are watching
Several open questions will shape how this plays out:
Who pays, and who benefits. The owner-charterer-manager split has not gone away. The most successful products serve a buyer whose incentives align with the value created. Regulation is forcing a shared emissions P&L, but commercial arrangements lag rules, and we are watching how quickly the contracts catch up with the software.
Greenfield versus displacement. The incumbents in ship management and chartering are deeply embedded and hard to remove. The interesting companies are not trying. They are finding workflows that were never digitised, or entering through a narrow wedge and expanding across the fleet as modules and vessels are added.
Software versus services versus hardware. A lot of “maritime tech” is really services or sensors with a software layer on top. Margins and scalability differ enormously, and the market is starting to price that difference clearly.
Cyclicality. Shipping is a cyclical industry, and software demand tethered to fleet growth or the newbuild orderbook will move with it. Efficiency- and compliance-driven demand is more resilient, because it is valuable in a downturn as well as a boom.
Autonomy. Uncrewed vessels and autonomous systems are attracting attention and capital. The near-term value lies in software that makes crewed shipping smarter.
Takeaways
Maritime is where supply chain software was a decade ago: a large, fragmented, under-served industry that has just acquired the connectivity, the regulatory pressure and the AI tooling it was missing. The market is small relative to the trade it carries, but it is growing in the low teens, consolidating quickly and, for the first time, attracting serious capital.
The winners will not be the companies that put a modern interface on old workflows. They will be the ones that own operational data, serve the buyer whose incentives match the value, and use agents to do the work rather than describe it. At Blume, we are actively looking for the next generation of maritime technology leaders building at this intersection, particularly those building in emissions compliance, voyage intelligence, and commercial-side workflow automation with durable data advantages. If you are one of them, we would like to hear from you.
