Digitalizing a $15–32 billion industry that still runs on fax
PortSupply360 is building the modern marketplace for maritime supply — connecting shipping companies with suppliers, replacing paper with cryptographic proof, and capturing a market with almost zero digital penetration.

Why now?
A massive market still on paper
Ship chandling generates $15–32 billion annually across 1,500+ ports in 126+ countries. Yet the vast majority of transactions still happen over email, fax, and phone — with paper-based proof of delivery.
Digitalization is accelerating
The maritime digitalization market is projected to grow from $175B to $395B by 2033. Ship owners and operators are actively seeking digital procurement solutions — but the options are either enterprise-heavy or outdated.
No dominant marketplace exists
Unlike most B2B industries, maritime supply lacks a modern, accessible marketplace. Existing solutions are either expensive ERPs (Supply Logic, SERTICA) or legacy platforms (ShipServ). There is a clear gap for a modern, marketplace-first platform.
The opportunity
Maritime procurement is one of the last major B2B verticals without a dominant digital marketplace. Competitors are either legacy enterprise systems with six-figure implementations (SERTICA, Supply Logic, ShipCentric) or platforms that haven't innovated in a decade (ShipServ). The mid-market — small to mid-size ship chandlers and fleet operators — is massively underserved. That's our entry point.
Competitive landscape
| Platform | Type | Target | Our edge |
|---|---|---|---|
| ShipServ | Legacy marketplace | Enterprise | Modern UX, lower barrier |
| SERTICA | Fleet ERP | Large fleets | Marketplace-first, serves both sides |
| Supply Logic | Chandler ERP | Suppliers only | Two-sided, no ERP overhead |
| SeaProc | eProcurement | Buyers | Digital signing, full lifecycle |
| PortSupply360 | Modern marketplace | Both sides, SME+ | — |
What makes us different
Cryptographic delivery proof
Every delivery is signed digitally via a secure link. No paper, no app download, no account needed. The signed PDF receipt uses HMAC-SHA256 — tamper-proof and legally defensible.
Two-sided marketplace
We connect shipping companies (buyers) with suppliers (sellers) through a connection-first model. Customer-specific pricing, multi-port warehousing, and fleet management are built in.
Low barrier, high retention
Free to start, instant value. Once a supplier has their catalog and warehouse fees configured, switching costs are high. The network effect grows with every connection.
Built for both sides
Unlike ERP solutions that serve one side, PortSupply360 serves both buyers and sellers — creating a flywheel where each new user adds value for the other side.
Where we are today
We're in early development with a fully operational platform. The core product is built and we're actively onboarding early access users.
The bigger vision
Maritime supply is our entry point — but not our ceiling. The maritime industry is a $15 trillion global ecosystem with deep inefficiencies across logistics, compliance, crewing, and operations. PortSupply360 is the first module in a larger platform vision. As we build the supplier–buyer network, we create the foundation for adjacent products across the maritime value chain.
Based in Sweden — a nation with deep maritime heritage, strong tech infrastructure, and a culture of building reliable, well-designed tools.
