What purtel does
purtel.com GmbH is a German wholesale white-label IP service provider founded in 2004 and headquartered in Langenzenn, Bavaria. The company enables more than 100 regional and municipal network operators (Netzbetreiber), fiber operators, and telecommunications resellers across Germany to deliver internet, telephony, IPTV, and hosted PBX services to residential and business end customers without owning and operating a full IP service stack. purtel's B2B channel partners resell its services under their own brands to end customers; the company does not sell directly to consumers.
The platform operates as a 3play/4play IP-dienstleister across eight nationwide Points of Presence with 400G peering at DE-CIX Frankfurt. The modular product portfolio is built around purISP (Layer-3 ISP-as-a-service with redundant BRAS, IPv4/IPv6 dual-stack, CGN, and bandwidth management), purTEL (VoIP telephony with fraud protection, SIP trunks, and Microsoft Teams Operator Connect integration via hosted AudioCodes SBCs), purPBX (hosted cloud PBX with IVR, conferencing, and mobile integration), purIPTK (SIP trunk connectivity with certified profiles for Auerswald, innovaphone, UNIFY, AGFEO, Bintec, and others), purTV (IPTV with DVB-C and thematic channels), purWiFi (TR-369/USP-based managed WiFi partnered with Axiros), purACS (zero-touch CPE provisioning for AVM Fritzboxes), a 4Play mobile offering via newsim, and the strategic Open Access Transaktionsplattform — a wholesale L2BSA marketplace connecting network operators with service providers, launched in March 2025 and reaching "Ready for Service" status in October 2025.
Revenue is generated entirely through B2B wholesale contracts: subscription and per-channel/per-seat recurring fees for ISP and telephony, transaction and platform fees for Open Access, managed services fees for CPE provisioning, and individually negotiated quote-based pricing. Go-to-market relies on direct enterprise sales to German network operators and a strong industry event presence (Fiberdays, ANGA COM, FRK-Kongress, BREKO Jahrestagung, Buglas). On November 5, 2024, the company transitioned to new owner-management under Achim Hager, Christian Kuhlmann, and Dr. Markus von Voss as both shareholders and Managing Directors, and since then has accelerated product launches (Open Access platform, 400G DE-CIX, Managed WiFi, newsim mobile), sales hires (Norbert Peters, Jochen Wilms), and ecosystem partnerships (OpenXS, vitroconnect, Axiros, WEMAConnect, BITConEx).
