What LEUK Teleport & Data Centre does

LEUK Teleport & Data Centre (legally Signalhorn AG) operates a 50-year-old satellite teleport and data centre facility in Leuk-Stadt, Switzerland, serving government, enterprise, maritime, NGO, and broadcasting customers globally. The facility combines a 4MW data centre (expandable to 20MW) with 5,000m² of data storage and over 90 antennas providing satellite visibility from 70E to 55W across C-Band, Ku, and Ka frequencies. It is marketed as Europe's only 100% green teleport and data centre, powered by onsite solar (including a world-first installation on legacy 32m C-band antennas in partnership with CKW AG) and local hydroelectric power. Data centre services span a Colocation Zone (up to 10KW per rack) and a Dedicated Zone (up to 45KW per rack) for high-performance computing, while satellite services offer multi-orbit (LEO, MEO, GEO) connectivity through partnerships with SES, Intelsat, Eutelsat, and OneWeb.

The company generates revenue primarily through recurring subscription and managed-services contracts. Colocation fees are based on space, power density, and connectivity, with bespoke multi-year contracts for the Dedicated Zone; satellite services are tiered on committed/peak bandwidth and orbit. Distribution is largely direct enterprise sales, supplemented by the Sat@Sea channel partnership (which serves 80+ superyachts from Dubai and Viareggio) and the 2023 ConnectiviTree Global Alliance for fibre distribution. All customers are supported by a 24/7 multilingual Network Operations Centre with team members averaging 25+ years of platform experience. The customer base spans European governments, financial and broadcast enterprises, humanitarian NGOs (40+ sites across multiple continents), and maritime/superyacht operators.

Strategic positioning in 2022-2023 has been defined by a rebrand from Signalhorn to LEUK Teleport & Data Centre, a multi-phase solar transformation, and an expansion of multi-orbit service offerings. The company is privately held with no disclosed institutional investors beyond a 2014 Metric Capital Partners event, is led by CEO John Harris alongside COO Andrew Lucas and CTO Matthias Riede, and has no disclosed revenue or headcount growth data.

Broad incumbents

• Equinix: Global colocation and interconnection leader with extensive European footprint including Zurich and Geneva. Comparable to LEUK's data centre business for enterprise and carrier customers, but operates at vastly greater scale and ecosystem density.
• Intelsat: Global satellite operator and LEUK partner providing C-/Ku-/Ka-band capacity worldwide. Overlaps with LEUK at the managed-connectivity and teleport infrastructure layer, but operates as a broad incumbent across multiple orbits and geographies.
• ViaSat: Major satellite operator and managed-connectivity provider serving government, maritime and enterprise. Comparable as a multi-orbit managed services incumbent, though primarily U.S.-anchored and vertically integrated into terminal manufacturing.
• SES: World's leading satellite operator and long-standing LEUK partner. Operates GEO and mPOWER MEO constellations; owns teleports of its own. A broader incumbent with overlapping teleport and managed-connectivity capabilities.

Direct peers
