What SEA-NET does

SEA-NET GmbH is a Rostock-based (with a second office in Stralsund) IT service provider founded in 2009 that plans, implements, and supports IT infrastructures specifically for ships operating on European inland waterways. The company targets river cruise operators, passenger ships, inland waterway vessels, and shipyards undertaking new builds or conversions, and states it manages more than 90 river cruise vessels across Europe. Its portfolio is organized into eight service lines: Network Services (LAN/WAN and ship-to-shore links), Internet Solutions (hybrid 5G/LTE and Starlink satellite connectivity with bandwidth management, channel bonding, and automatic failover), IT Consulting, Project Management, Cyber Security, Entertainment Systems (IPTV, video-on-demand, digital signage), Server & Client Management (Windows Active Directory, Linux, virtualization), and Technical Support.

Underlying the service offering is a hybrid connectivity stack built around a Multi-WAN router with channel bonding (delivered via partnership with Peplink), integration of Starlink as an authorized installation partner, bandwidth control and prioritization (QoS), and an in-house branded SIM/eSIM product (SEA-DATA) providing Europe-wide data. Enterprise networking and security components are sourced from HPE and Cisco. SEA-NET does not develop custom software or APIs; its stated model is integration of proven third-party systems, including intelligent interfaces where appropriate.

Commercially, SEA-NET monetizes through a mix of project-based professional services (IT consulting, new-build and conversion implementation, hardware sales) and recurring managed services delivered under Service Level Agreements with monthly billing. Pricing is quote-based and not publicly disclosed, with smaller project solutions starting in the four-digit (EUR) range. Go-to-market is direct enterprise field sales, consultative in style, with a strategic-IT-partner positioning aimed at long-term fleet-level relationships rather than transactional sales. The company is privately held by founder/CEO Matthias Damm with no external institutional investment disclosed.

The company delivers end-to-end IT services from project planning through implementation to ongoing support for ship operators, shipyards, and passenger ships.

Product overview

SEA-NET is a maritime IT service provider offering a portfolio of professional services for river cruise ships and maritime vessels rather than a single software product.

These services are delivered as professional/managed services rather than packaged software products, with solutions tailored for ship environments including vibrations, fluctuating power, and limited bandwidth conditions.

Comparable to SEA-NET in delivering hybrid connectivity hardware and airtime to maritime operators, with a strong overlap in vessel internet/network infrastructure.

Comparable to SEA-NET's passenger vessel focus, multi-WAN connectivity, and onboard IT support for cruise and ferry operators.
• IEC Telecom: Satellite communications provider delivering VSAT, Starlink integration, and managed network services to maritime, land, and government customers. Comparable to SEA-NET in hybrid LEO/MEO/GSM connectivity solutions and system integration, though IEC operates across broader maritime and government verticals.

Broad incumbents

• Speedcast: Large global provider of satellite communications and managed network services across maritime, energy, and enterprise segments. Comparable to SEA-NET in managed maritime connectivity and IT services, but with a much larger global footprint across commercial shipping, offshore, and cruise.
• Radio Holland: Global marine electronics specialist providing navigation, communication, and IT service solutions to shipyards and shipowners. Comparable to SEA-NET in maritime IT installation and commissioning work but broader in scope, also covering navigation electronics and traditional radio/communication equipment.
• Viasat (Maritime): Major satellite operator (post-merger with Inmarsat) delivering global maritime connectivity including VSAT and LEO services. Comparable to SEA-NET as an underlying connectivity provider whose services SEA-NET integrates and manages; competes indirectly at the connectivity layer via partner and direct relationships.
