What 1&1 Versatel does

1&1 Versatel GmbH is a German B2B telecommunications carrier headquartered in Düsseldorf and a wholly-owned subsidiary of 1&1 AG within the United Internet Group. The company was founded in 1999 and operates one of Germany's largest fiber optic networks, comprising over 68,500 km of optical fiber across more than 350 cities, 30 fully redundant Points of Presence, and a nationwide MPLS backbone with up to 100 GBit/s transmission capacity. The company delivers a 99.99% network availability guarantee through a 24/7 Network Management Center in Essen and processes approximately 2 billion voice minutes per month across its interconnection infrastructure.

The product portfolio spans fiber internet (Office Fast & Secure, Glasfaser Connect/Premium, Glasfaser Business Direkt up to 10 GBit/s), business DSL, IP telephony (Voice SIP, Business Phone), unified communications integrations with Microsoft Teams, RingCentral, and NFON Cloudya, SD-WAN and VPN networking solutions, managed firewall and DDoS protection, and carrier/wholesale services including transport networks, voice interconnection, IP transit, Layer 2 Bitstream Access (L2BSA), and white-label platforms for municipal utilities. The company targets German business customers across SMB, mid-market, enterprise, and public sector segments, with dedicated vertical solutions for hospitality, automobile dealerships, media/broadcasting, and public administration/healthcare.

Revenue is generated primarily through recurring subscription fees for connectivity and telephony, with project-based revenue from professional services (in-building fiber cabling, network integration) and wholesale carrier contracts. Pricing ranges from publicly listed entry-level fiber tariffs at €39.90/month to custom-quoted enterprise and wholesale contracts. Distribution is multi-channel: direct enterprise field sales, inside sales, the Vertriebspartner reseller program, and a dedicated wholesale carrier team. In November 2025, United Internet AG completed the sale of its Versatel unit to 1&1 AG, consolidating the B2B fiber carrier within the 1&1 group structure as part of a broader segment reporting reorganization effective January 2026.

Direct peers

• Plusnet (German B2B): German B2B telecommunications provider (part of Deutsche Telekom group) offering fiber, DSL, voice, and managed services to business customers. Comparable target market and product portfolio, with overlap in serving mid-market German enterprise connectivity customers.
• euNetworks: European fiber infrastructure operator providing dedicated fiber, data center connectivity, and wavelength services to wholesale and enterprise customers. Comparable as a fiber-ownership-driven carrier serving carriers and B2B customers with similar transport and wholesale products.
• Colt Technology Services: European-focused B2B fiber and data center services carrier serving enterprise customers across multiple countries. Highly comparable business model — dedicated fiber, Ethernet, SD-WAN, voice, and managed services for mid-market and enterprise — though with broader European rather than German-only geographic focus.
• Deutsche Glasfaser: German fiber-to-the-home and business operator focused on underserved regions. Comparable as a Germany-only fiber carrier with overlapping FTTH/B infrastructure investment and similar B2B fiber ambitions in regional and underserved markets.
• Lumen Technologies: Global enterprise networking and carrier services company offering fiber, wavelength, Ethernet, voice, and managed SD-WAN. Comparable in carrier-services business model and product portfolio, though with a global footprint versus 1&1 Versatel's German-only focus.

Broad incumbents

• Telefónica Germany (O2): Major German mobile and fixed-line operator (O2 brand) increasingly focused on B2B fiber and SD-WAN. Comparable as a broad incumbent expanding into enterprise connectivity and competing for the same German mid-market and enterprise customers.
• Vodafone Germany: Major German fixed and mobile telecom operator serving consumer and business customers. Comparable as a B2B connectivity competitor with bundled offerings, larger scale, and growing enterprise fiber presence — competing for the same German business customer base.
• Deutsche Telekom: Germany's dominant telecommunications incumbent operating fixed, mobile, and wholesale services nationwide. Comparable as a major B2B connectivity provider, though Deutsche Telekom is a much larger incumbent with bundled offerings and is also 1&1 Versatel's largest wholesale access partner via L2BSA.

Regional players

• NetCologne: Regional telecommunications provider serving the Cologne/Bonn region with fiber, DSL, and business services. Comparable in fiber-based B2B product portfolio but geographically restricted to western German regional markets versus 1&1 Versatel's nationwide presence.
