Opennet Gmbh

What Opennet Gmbh does

OpenNet GmbH is a Germany-based Open Access IT platform company established in 2024 in Neumünster as the German subsidiary of OpenNet Holding, which is 100% owned by Denmark's Norlys Group. In June 2025, the German entity was converted into a 50/50 joint venture with three German municipal network operators (SWN Stadtwerke Neumünster, Stadtwerke Geesthacht, and Breitbandnetz Gesellschaft), giving OpenNet a locally embedded ownership structure while preserving Norlys control of OpenNet Denmark. The company operates a many-to-many platform that connects fiber network operators (Glasfasernetzbetreiber) with internet service providers (Diensteanbieter) through standardized APIs, contracts, and processes, eliminating the need for bilateral integrations between each operator and ISP pair. Core products include the OpenNet Platform itself, the Fiber BSA (Bitstream Access) product delivering L2 connectivity to a Point of Interconnect, a standardized Service Catalog, and a structured Project Model for partner onboarding.

The company monetizes the platform primarily by charging network operators on a subscription basis with a pay-as-you-grow model following go-live, while onboarding ISPs free of charge to maximize the platform's addressable reach. As of early 2026, the broader platform covers 1.6+ million marketable FTTH addresses across Denmark and Germany, with 25 partners and approximately 100 active cooperations; the German footprint stands at roughly 450,000 FTTH addresses addressable via OpenNet and nine active partner operators/ISPs. Anchor customers include SWN/GIGA5 (with approximately 100,000 customers migrated onto a unified portal), Stadtwerke Flensburg, Breitbandnetz Gesellschaft, Stadtwerke Geesthacht, and the international ISP Bahnhof, alongside Danish references such as GlobalConnect, Telenor Denmark, and Norlys Fibernet. The German entity currently employs approximately six staff and is led by Managing Directors Kristian Olaf Plet Freiesleben and Lars Wiechmann, while the wider OpenNet group spans Germany and Denmark under unified OpenNet Holding ownership.
