Introduction
At the start of 2026, Navarino Group announced a partnership with ICG, which saw the global asset manager acquire a stake in Navarino, leading to an agreement between the group’s founders, Dimitris and Panos Tsikopoulos, to buy out Viasat’s minority 49 per cent stake in the entity.
This move won’t surprise many industry folk, particularly given the timing. The group kicked off 2025 with a bang, as Navarino announced the 100% ownership purchase of Castor Marine BV; the Dutch maritime service provider of satellite connectivity and IT services.
Maritime Connectivity Stalwart
Navarino is a global maritime technology service provider and a major connectivity, IT, OT and hardware solution provider in the shipping market.
In 2024, Valour Consultancy’s flagship report on The Future of Maritime Connectivity ranked Navarino as the fourth largest maritime service provider based on satellite connectivity revenues. Honing in solely on the merchant vessel market, Navarino’s connectivity and smart box, Infinity, is on nearly half of all merchant vessels using GEO VSAT services. The firm held a double-digit market share in maritime connectivity and smart box digitalisation services in 2024, Valour Consultancy estimates.*
Further to establish the company’s strength and reputation, some of its merchant customers have been with the company for nearly 30 years, which shows how well respected the service provider is.
*Excludes GMDSS L-band – Low-speed & No Voice satellite services
Background Legacy
Dimitris Tsikopoulos, and brother, Panos Tsikopoulos founded Navarino back in 1996, driving remarkable growth and focusing on the latest satellite connectivity services.
Initially, this was Inmarsat-A, -B and -C, followed by Mini-M, Fleet-77, and Fleetbroadband, then GEO VSAT services. To provide some context, Fleet-77’s maximum download speed was 64kbps. The arrival of Fleetbroadband in 2006, pushed downlink to 432kbps.
Navarino’s management team has balanced market growth with commerciality and profitability astutely. The firm is renowned for its digital value-added services, particularly its smart box product series, Infinity, as its connectivity services today. In fact, the company’s best-selling product.
Connecting the Dots
Many people will wonder how an American satellite operator ended up with 49 per cent of a Greek-headquartered connectivity and technology service provider.
For those maritime anoraks, Stratos Global (a satellite communications company) acquired the 49 per cent minority stake in Navarino Telecom S.A. back in 2005. At the time, Navarino was Stratos’ biggest distributor, and Stratos likely wanted exclusivity of Navarino’s channel to market. As such, part of that 2005 deal meant Navarino also ensured exclusive distribution agreements to source certain satellite communications services through Stratos.
Several years later, Stratos was acquired by Inmarsat (2009), and more than a decade later, Inmarsat was acquired by Viasat, thereby holding a stake in Navarino through those changing ownerships.
However, Navarino has always been run independently of Inmarsat/Viasat. The only governance was that two members of Inmarsat’s senior management team were on the board of Navarino.
Why Now and Why ICG?
The relationship between Navarino and Inmarsat has always been independent. In some respects, Inmarsat was a strong but largely passive partner. Speaking to Navarino, it is clear ICG will help Navarino to grow its business further, thanks to its financial expertise. Looking at Inmarsat/Viasat, the relationship will l continue as business as usual, as it had before ICG.
In a sector as relationship-driven as maritime connectivity, personal ties often underpin commercial alignment. When Inmarsat first launched FX, Navarino was the first reseller to commit to, and attain, 1,200 vessels to the service in 2016
One of the most fascinating elements of this news is why now and why ICG Assets?
At first glance, the partnership between Navarino and ICG may seem like a straightforward financial transaction. In reality, it signals a strategic recalibration at a pivotal moment in the maritime technology market.
ICG is not a satellite operator, nor a direct competitor to Navarino’s vendor ecosystem. That neutrality is crucial.
For nearly two decades, Navarino’s minority shareholder was ultimately tied to Inmarsat: first through Stratos Global, then through Inmarsat, and most recently through Viasat. The only complication was that mergers were difficult while Inmarsat held 49%
The rise of LEO providers such as Starlink and the integration of OneWeb capacity into multi-orbit portfolios have fundamentally altered competitive dynamics. A service provider partially owned by a GEO-centric operator may find itself navigating questions about perceived alignment in a multi-vendor world. But most importantly, ICG will enable Navarino to further grow its maritime business.
ICG provides something different:
- Capital Without Commercial Conflict
As a global asset manager with deep experience in scaling mid-market technology businesses, ICG brings growth capital without product bias. Navarino is now structurally vendor-agnostic in both perception and governance.
- Acceleration in a Consolidating Market
Maritime connectivity is entering a new consolidation phase. Service providers require scale to negotiate capacity, invest in digital platforms, and maintain margin as bandwidth commoditises. ICG’s backing gives Navarino acquisition firepower. Castor Marine may soon not be the latest transaction of Navarino.
- Digital Expansion Beyond Connectivity
Connectivity margins are tightening. Value is shifting toward cybersecurity, IT-as-a-service, IoT, and optimisation platforms. Navarino’s Infinity ecosystem and broader digital portfolio represent higher-margin, recurring revenue streams. ICG’s technology investment track record suggests alignment with this shift.
- Optionality for the Future
Private capital typically operates on defined investment horizons. While no exit strategy has been stated, partnerships of this nature often position companies for eventual strategic sale or IPO.
ICG’s involvement could therefore represent both growth capital and preparation for the next structural step in Navarino’s evolution. Expect more strategic acquisitions in the future by Navarino, being the pursuer.
In summary, ICG brings capital, neutrality, and scale at a moment when maritime service providers must choose between consolidation, specialisation, or decline. From conversations inside Navarino, ICG has an enormous amount of trust in Navarino’s leadership team, which isn’t surprising as the company has been generating healthy profits and commercial growth for many years.
Navarino’s Business
Navarino is a leading global provider of maritime IT, connectivity, and value-added digital services for the commercial shipping and offshore sectors.
Navarino operates from 12 offices across Europe, Asia, the Middle East, and North America. Navarino ranks among the top maritime service providers globally, with a significant share of worldwide retail revenues across the L-band, LEO, and VSAT segments.
Its strong customer base: particularly in Greece, Europe as a whole and Asia, has expanded steadily over the past decade, underpinned by increasing global demand for hybrid and high-bandwidth connectivity.
Its flagship digital product is the Infinity platform, and it has become the most widely deployed smart-box system in the maritime market. The smart box is deployed on more than 12,000 vessels globally. To complement the platform, a growing range of digital services, including networking, IT management, IoT, cybersecurity, and other IT-as-a-service offerings. Navarino’s diversified portfolio positions it at the intersection of connectivity, digitalisation, and maritime technology.
To augment its merchant shipping business further, the addition of Castor Marine add leading offshore energy customers and also superyachts to the group’s portfolio. Castor has retained its independent brand outside of the Navarino Group, but the majority of internal system integration has been implemented.
Connectivity
People wonder how Navarino’s relationship with Inmarsat go in the future. In some regards, nothing will change. It’s business as usual, insiders say. Navarino remains a Tier 1 reseller of Inmarsat and with its large holding of FX, GX and growing NX vessels, will always be able to speak to the top personnel at Inmarsat.
Recap Navarino’s Connectivity Business
In early 2023, Navarino became an authorised maritime reseller of Starlink, marking a strategic expansion into LEO satellite services. By the end of 2024, the company had 4,100 active Starlink terminals, reaching 5,100 by September 2025. Group installations exceeded 6,000 by year-end 2025, making Navarino one of the world’s largest maritime LEO resellers.
This rapid adoption reflects the company’s early move toward hybrid connectivity, combining GEO, LEO, MSS, and 5G near-shore communications to deliver optimised performance, redundancy, and cost efficiency.
Navarino is the world’s largest value-added reseller (VAR) of Inmarsat FX, with over 2,300 vessels equipped by year-end 2025. The company also supports Inmarsat GX and NX services, the latter integrating OneWeb’s LEO offering.
In the GEO VSAT segment, Navarino provides Ku-band services – IntelsatOne Flex and SES Networks, to roughly 1,350 vessels. Additionally, it has several hundred vessels on its own proprietary GEO Ku-band VSAT network (courtesy of Castor Marine).
The company’s L-band portfolio (Iridium Certus, Iridium OpenPort, and Inmarsat FleetBroadband) remains a stable contributor to revenues, particularly for safety and redundancy applications. Navarino is also among the few providers offering Inmarsat-C GMDSS services.
Digitalisation
Beyond connectivity, Navarino has developed a comprehensive ecosystem of digital tools and services, accounting for 30 per cent of the company’s total revenues (Valour Consultancy, 2025).
These include:
- Infinity: industry’s leading smart-box platform for bandwidth management, virtualised applications, and hybrid network optimisation.
- Quazar: complete IT-as-a-Service offering providing proactive IT management and maintenance.
- Angel: certified cybersecurity platform offering endpoint protection and SOC services.
- IoT and Fleet Tools: custom applications for remote monitoring and network control.
In November 2024, Navarino launched Navarino Elements, a specialised division focused on bridge and navigation technologies, which achieved greater than $3 million in its first year. Navarino is also the majority shareholder of Forecode, which develops proprietary HSQE software for ship operators.
The Future
The Navarino and ICG partnership arrives at a moment of structural change in maritime communications.
Three major opportunity vectors emerge:
Multi-Orbit Optimisation
The hybrid era is here. The battle of networks, or network of networks. Each to their own terms.
In short, vessel owners now expect seamless integration of GEO, LEO, MSS, and 5G. Navarino’s Infinity platform places it in a strong position to act as an orchestrator rather than a reseller.
Consolidation
With smaller regional service providers struggling to compete on price and platform capability, acquisition-led growth remains likely. ICG’s backing may enable Navarino to pursue additional bolt-on acquisitions similar to Castor Marine early last year. The next question is, who is next?
Digital Service Monetisation
Connectivity revenues face margin compression. Digital services such as cybersecurity, IT-as-a-service, IoT, HSQE software, provide recurring, higher-margin revenue streams less exposed to bandwidth commoditisation.
If executed effectively, Valour Consultancy believes Navarino’s future may resemble a maritime technology integrator rather than a traditional satellite service provider. Navarino would argue that it is already a leading technology developer, owning proprietary tech, as well as being a major integrator
Obstacles
However, the path forward is not without complexity…
Margin Pressure
LEO bandwidth pricing has disrupted traditional VSAT economics. Service providers must justify value beyond Mbps.
Vendor Relationships
While independence removes perceived conflicts, Navarino must carefully balance relationships with legacy partners such as Inmarsat while expanding further into LEO ecosystems.
NexusWave has achieved moderated success. But will its evolution and development impede Navarino’s other connectivity service?
Talent & Scale
Rapid growth, particularly through M&A, places pressure on integration, internal systems, and management bandwidth. Just ask the folks at SES and Intelsat about its internal systems, picking the best one moving forward. Navarino will likely be aware of this when comparing the Flex service with its proprietary GEO VSAT business. Great commercial offer versus agility and flexibility.
Customer Expectations
Shipowners increasingly expect terrestrial-like performance at sea. Meeting these expectations profitably will define the next phase of competition.
Conclusion
Navarino’s partnership with ICG marks more than a change in shareholding; it represents a strategic reset.
Freed from operator-linked minority ownership and backed by institutional capital, the company enters 2026 with greater structural independence and financial flexibility. The move reflects wider shifts within maritime connectivity: vendor neutrality, multi-orbit optimisation, digital monetisation, and consolidation.
Whether this new chapter leads to sustained organic growth, further acquisitions, or an eventual liquidity event remains to be seen. What is clear is that Navarino has positioned itself not merely as a connectivity provider but as a broader maritime technology developer, at a time when the industry is being redefined. Expect more digital service launches from Navarino at Posidonia 2026 this summer.
