Singapore’s maritime industry may not get the same attention as fintech or AI, but it remains one of the foundations of the country’s economy. Around that critical infrastructure, a quieter maritime tech startup ecosystem is emerging. The 10th edition of the PIER71 Smart Port Challenge has brought fresh attention to this space, with PIER71 having supported some 170 start-ups since 2018, collectively raising over S$150 million in funding. The five startups below show how Singapore-linked maritime tech companies are solving practical, high-value problems across shipping, ports and vessel operations.
Here is why Southeast Asia’s next B2B startup opportunity may be hiding on the factory floor
Portcast: Predicting disruption before it hits the bottom line
Global trade routes are not predictable in the way shipping schedules suggest they should be. Weather, port congestion, labour disputes and geopolitical disruptions all introduce delays that ripple through a supply chain long before anyone downstream notices. Portcast was built to surface those risks early enough that logistics teams can actually act on them rather than simply react after the fact.
The Singapore-based company connects shipment data to orders, contracts and invoices, with AI surfacing risks before they escalate and recommending the right actions to protect service levels and margins. In November 2024, Portcast raised USD 6.5 million in a Series A round led by Susquehanna Asia VC, with the funding directed towards generative AI applications for risk management, transport planning and invoice auditing, alongside deeper expansion across Asia Pacific and Europe. The company’s traction speaks to a real operational pain point. Customers using Portcast’s predictive visibility have reported reductions in overall port fees by 20% and manual work by 80%, figures that explain why freight forwarders and manufacturers keep adopting the platform even as the broader logistics tech space has consolidated.
BeeX: Sending robots where divers used to go
Inspecting the underside of a ship hull, a port structure or offshore infrastructure has traditionally meant sending a diver into often dangerous conditions or deploying a remotely operated vehicle that still requires a large support vessel and a specialised crew. BeeX set out to remove both of those constraints.
BeeX is a Singapore-based subsea robotics company pioneering autonomous Hovering Autonomous Underwater Vehicles for commercial and defence applications, addressing the high operational costs that conventional subsea inspections incur through professional divers and remotely operated vehicles. Customers have reported up to 95% less CO2 emissions, 50% lower risk to life and tenfold better efficiency compared to conventional inspection methods. The company launched a SGD 10 million Series A round in September 2025 to support global scaling, with more than half the round soft-committed before the raise even formally opened, reflecting the level of demand it was seeing for its vehicles.
BeeX has also moved beyond its commercial roots into research infrastructure. It recently partnered with the Singapore Institute of Technology to launch the Autonomous Marine Foundry, a joint lab and demonstration facility at SIT’s Punggol campus that allows researchers and enterprises to test and develop maritime robotics applications.
Tagvance: Keeping track of people and assets where visibility is hardest
Ports, shipyards and industrial terminals are large, often chaotic environments where knowing exactly where personnel and equipment are located at any given moment is harder than it sounds. Confined spaces, large outdoor areas and constantly moving assets make this a genuinely difficult tracking problem and one with real safety implications when something goes wrong.
Tagvance provides high-accuracy tracking and monitoring solutions that allow businesses to determine, in real time and with high precision, the location of people and assets in industrial spaces, helping maritime operators improve operational efficiency, capacity utilisation and work safety while reducing costs.
The system layers positioning data with environmental sensor information so operators understand not just where something is but what conditions exist at that location, with IoT nodes placed around the tracking area and tags that can last several years on Bluetooth and LoRa radio frequencies suited to both outdoor and confined-space tracking. It is a less visible category of maritime tech than autonomous robots or predictive software, but the operational safety case is straightforward and the demand from port operators is consistent.
Greywing: Turning scattered maritime data into decisions
Vessel operators have historically pieced together critical operational decisions from a patchwork of emails, spreadsheets, vessel tracking systems and phone calls. Greywing was built on the premise that this fragmentation was costing the industry time, money and, in some cases, safety margin.
Greywing serves ship operators through several connected products: Flotilla monitors vessels to identify fleet-level patterns and risk vectors in advance, CRY4 gives crew managers and masters intelligence about a vessel’s current or proposed route to support decisions on the safest and most cost-effective ports of call and Semaphore simplifies communication with the large numbers of port agents involved in planning a port call.
The company raised USD 2.5 million in seed funding from investors including Flexport, Y Combinator and Motion Ventures, with the round supporting development of intelligent vessel management systems designed to become more autonomous as the platform’s data and algorithms mature. Greywing’s founders have been candid about the scale of the problem they are solving. As one of the founders put it, decision makers were historically fed critical details from separate channels and forced to manage them across different platforms, making it genuinely difficult to turn scattered data points into actionable intelligence.
MagicPort: Making the port call itself less painful
A port call sounds like a simple event: a vessel arrives, conducts its business and departs. In practice, it involves coordinating agents, suppliers, service providers, invoices and communications across multiple parties who are rarely working from the same system. MagicPort set out to collapse that fragmented process into a single operational platform.
MagicPort connects charterers, ship owners and managers with a trusted network of agents, suppliers and service providers worldwide to enable smart and efficient port call operations, with the platform helping operators manage port calls, track vessels and gain visibility into operations while reducing complexity, manual work and mistakes.
More than 300 shipping companies around the world now run their port calls on the platform, a scale that suggests the company has solved a genuinely shared pain point rather than a niche one. The product spans port call management, AI-powered automation for tasks like document handling and invoicing and a maritime intelligence layer that turns operational data into insight for shipping teams managing dozens of port calls simultaneously.
Why capital alone does not solve maritime problems
What distinguishes maritime tech from many other startup categories is how little capital alone accomplishes without the right operational relationships. A fintech startup can often validate a product with a relatively small group of early customers and digital distribution. A maritime startup typically needs access to vessels, ports, terminals and the corporations that operate them, none of which can be acquired purely through advertising spend or a slick onboarding flow.
This is precisely the gap that programmes like PIER71 exist to close. The Smart Port Challenge brings maritime corporations into the process directly, with each company contributing specific challenge statements that reflect real operational problems they are willing to pay to solve. The 2026 edition is structured around 20 innovation opportunities across four areas, supported by 19 innovation partners, including ABB, ABS, CMB.TECH, PSA Ventures, Wilhelmsen Ships Service and Mitsui O.S.K. Lines.
For an early-stage startup, that kind of testbedding access and domain expertise is often more valuable than the funding itself, because maritime corporates are notoriously slow to adopt technology from vendors who have not proven themselves in a live operational setting first.
The companies that matter may be the ones you do not notice
None of the five companies above are household name, and that is rather the point. Maritime technology succeeds when it disappears into the background of daily operations: a vessel that avoids an unnecessary delay, an inspection that no longer requires a diver, a port call that closes out without a missed invoice.
Trends clearly indicate that Southeast Asia’s most valuable maritime tech startups will not be the ones generating headlines but the ones quietly improving the operational decisions that keep one of the region’s most important industries moving. The same instinct for unglamorous but structurally important problems runs through other corners of Singapore’s deep tech startup ecosystem, where the companies attracting serious institutional backing tend to be solving problems that never trend on social media but matter enormously to the people running the underlying systems.
