EXA Infrastructure: High-Capacity Digital Infrastructure & Fiber
EXA Infrastructure provides high-capacity fiber connectivity and subsea cable solutions across Europe and North America for hyperscalers, carriers, and enterprises.
Overview
EXA Infrastructure is a leading global digital infrastructure provider, headquartered in London, that specializes in high-capacity terrestrial and subsea fiber-optic connectivity. Formed in late 2021 following the acquisition of GTT Communications' infrastructure assets by I Squared Capital, the company has quickly established itself as the largest dedicated infrastructure platform connecting Europe and North America.
The company’s core business revolves around providing the "backbone" of the internet. Their extensive network includes over 151,000 kilometers of fiber, 500+ Points of Presence (PoPs), and 13 Tier 3 data centers. EXA serves a sophisticated client base consisting of hyperscalers (such as AWS, Google, and Microsoft), global carriers, government agencies, and large enterprises in data-intensive sectors like finance, media, and research.
Historically, the assets within EXA’s portfolio represent decades of strategic investment, including the integration of legacy networks from Interoute, Hibernia Networks, and KPN International. Today, EXA focuses on three primary pillars:

Operating in a market driven by the exponential growth of data consumption, EXA’s strategy is centered on continuous network expansion and the deployment of next-generation optical technology to support the evolving needs of the global digital economy.
Positioning
EXA Infrastructure positions itself as the "backbone of the digital economy," emphasizing its role as the essential, invisible layer that enables global digital transformation. Their market positioning is centered on three key pillars: Scale, Speed, and Specialization.
In a competitive landscape dominated by traditional Tier 1 carriers (such as Lumen, Orange, or Deutsche Telekom), EXA differentiates its brand by highlighting its lack of "legacy baggage." While traditional telcos are often encumbered by aging retail operations and complex consumer services, EXA positions itself as a streamlined, infrastructure-focused alternative. Their messaging targets the "builders of the internet"—the architects and engineers at hyperscalers and wholesale carriers—who value technical specifications, route diversity, and low latency over broad service bundles.
Key elements of their positioning strategy include:
- The Transatlantic Leader: Leveraging the lowest-latency subsea routes to claim dominance in the North America-to-Europe corridor.
- The AI-Ready Network: Positioning their high-bandwidth 400G/800G capabilities as the necessary infrastructure for the AI revolution.
- Regional Depth, Global Reach: Emphasizing deep terrestrial penetration within Europe combined with critical intercontinental gateways.
By focusing on being a "specialist provider," EXA successfully distances itself from the "commodity" perception of telecommunications, instead framing its assets as high-value, strategic investments for its customers' long-term growth.
Differentiation
The EXA Infrastructure product suite is defined by its massive scale and strategic geographic footprint, encompassing over 151,000 kilometers of fiber across 34 countries. A primary differentiator is their ownership of critical subsea assets, including the GTT Express (formerly Hibernia Express), which provides the lowest-latency route between New York and London. This technical advantage is a cornerstone for financial services and high-frequency trading firms.
Key product innovations and advantages include:
- Diverse Routing: EXA offers unique, high-diversity routes that bypass traditional congested hubs, providing greater resilience for mission-critical traffic.
- Ultra-High Capacity: Their network is engineered to support 400G and 800G wavelengths, catering specifically to the data-heavy requirements of AI model training and hyperscale cloud synchronization.
- Subsea Leadership: With ownership of multiple transatlantic and Mediterranean cables, EXA provides seamless end-to-end connectivity between North America, Europe, and increasingly into the Middle East via their "Trans-Adriatic Pipeline" routes.
- Dark Fiber Availability: Unlike many incumbents who prefer selling managed services, EXA remains a major provider of dark fiber, allowing customers to deploy their own equipment and control their own optical layers.
Their focus on "Infrastructure-as-a-Service" at the physical layer ensures that their products are optimized for performance, scalability, and security, rather than being bundled with unnecessary software-layer add-ons.
