TMTkom

What TMTkom does

TMTkom GmbH is a German full-service network construction provider (Komplettdienstleister) founded in 2000 in Mülheim an der Ruhr by Thomas Marasopoulos. The company delivers infrastructure services across three pillars: Glasfaser (fiber optic), Kupfer (copper networks), and Energie (energy). The fiber offering spans turnkey network-level 2–5 project execution, FTTx densification, FTTH subscriber connections (NE 4–5), system technology at PoP/NVt/HVt sites, and field service for activation and fault clearance. The copper pillar covers maintenance, repair, subscriber provisioning, and in-premise technical services. The energy pillar, added in 2021, delivers low and medium voltage construction, house connections, EV charging (Wallbox) installation up to 22 kW, and smart meter (iMSys, mME) deployment with LoRaWAN or cellular connectivity. Technology centers on trenchless civil works (Erdrakete, horizontal directional drilling, plowing), OTDR-based quality assurance, and a fleet of 120+ service vehicles.

The business model is project-based professional services sold directly to enterprise B2B clients: telecommunications network operators and carriers, municipal utilities (Stadtwerke) and energy suppliers (Versorger), municipalities (Kommunen), and real estate companies. Pricing is quote-driven per project scope, with no publicly disclosed rates; the company is currently positioned as a general contractor (since 2022) capable of taking end-to-end scope from planning through commissioning. GTM is direct enterprise field sales with a core geographic base in NRW and deployment reach into Bavaria and nationwide Germany. The company converts project work into recurring framework relationships, supported by a customer portal for inquiries and appointment management, and uses its website and job portal as primary demand and recruiting channels.

As of 2024, TMTkom employed 160+ qualified technical and commercial staff and reported annual capacity of 100+ km of civil trench, 10,000+ house connections, and 17,000+ residential units served. The firm converted to GmbH form in 2010 and added Dipl.-Ing. Florian Donath, MBA as a second managing director in 2026 to lead its next development phase. Ownership remains private and founder-led, with no disclosed external investors, subsidiaries, M&A activity, or public market presence.
