What Quadrivium Digital does

Quadrivium Digital is a UK-headquartered (London) data centre operator founded in 2022 that designs, builds and operates carrier-neutral interconnection facilities co-located with subsea cable landings across EMEA. Its core technology centres on a 'CLS-within-a-DC' architecture integrating Cable Landing Station infrastructure inside Tier III+ data centres, supported by buried marine borepipe with multiple Beach Manholes for direct submarine cable landing, SLTE-to-SLTE optical cross-connect capability across fibre pairs, spectrum and bandwidth, N+1 distributed redundant power with Tier IV resilience available for PFE hosting, and a Smart DCIM system targeting PUE below 1.25. The company has announced two campuses to date: a 20MW Chania, Crete interconnection and hyperscale hub developed in partnership with IPTO/Grid Telecom, and the 12MW QGEN01 facility in Genoa (9,000m2 building area, capacity for up to eight new submarine cable systems, dedicated borepipe and 1.2km fronthaul) expected to go live in Q3 2026, with management stating a broader plan for six European sites in total.

Revenue is generated through four product lines — Cable Landing Station Colocation, Carrier-Neutral Interconnection, Data Centre Colocation and a Landing-as-a-Service managed offering — under subscription and recurring-fee contracts with long-term commitments, per-port cross-connect charges, and one-time installation revenue tied to fibre pair, spectrum, kW and cabinet pricing. Pricing is quote-based and not publicly disclosed. Quadrivium serves four primary enterprise segments — subsea cable consortiums, telecom carriers, content providers and digital platforms, and hyperscale cloud providers — via direct enterprise field sales and a partnership channel, with named infrastructure and connectivity relationships including Arelion, Zayo Europe, Retelit and IPTO/Grid Telecom. Distribution is project-based and geographically focused on Mediterranean gateway locations serving European, Middle Eastern, Asian and African markets, with sales cycles characterised by long-term contracts and direct negotiation with major carriers and platform operators.
