What schleyer systemtechnik does

Schleyer Systemtechnik is a German regional IT and telecommunications (IT/TK) systems house serving small and medium enterprises (KMU) across Germany. Founded in 2011 in Althütte by Lukas Schleyer as a sole proprietorship, the company relocated to Rudersberg in 2014 and to its current headquarters at Gmünder Straße 65, Schorndorf, in 2020. The company positions itself as an independent single point of contact ("zentraler Ansprechpartner") for all IT and telecommunications matters of SME clients, with stated focus areas in ALL-IP transitions, IT infrastructure, and independent brokerage of communications and data solutions.

The product portfolio spans a modular SST Managed Services suite (SST Managed Monitoring, Managed Antivirus using the IKARUS T3.scan engine, Managed Smart Updates for Windows and 40+ applications, Managed Firewall/UTM, Managed Backup to German data centers with disaster-recovery virtualization, and Managed Mobile-Device for iOS and Android), IP telephony delivered through a flagship partnership with STARFACE GmbH (hybrid systems scaling from 1 to 3,000 users with Unified Communication & Collaboration features), and the venabo.ZEIT web-based time-recording software with integrations to DATEV, SAP, Navision, Lexware, Addison, BPS, Selectline, and microtech. Hardware provisioning covers TERRA workstations via WORTMANN AG, Kyocera/Epson peripherals via Bürotechnik Schwaben, and TK hardware from Snom, Yealink, Gigaset Pro, and EPOS/Sennheiser. Independent telecommunications provider brokerage is delivered through Epsilon (an HFO Group subsidiary). The underlying technology model is systems integration and service packaging of third-party platforms — primarily Securepoint, STARFACE, WORTMANN/TERRA, and venabo — rather than proprietary platform development.

Revenue mechanics combine recurring managed services subscriptions, project-based IT/TK deployments, one-time hardware sales, and commissions or fees from telecom provider brokerage. Pricing is quote-based and tailored per customer, with no publicly disclosed tiers; venabo.ZEIT uses a modular pay-per-feature subscription. Go-to-market is direct and consultative via phone, email, callback forms, and on-site engagement, augmented by referrals through the IT-Systemhausverbund network of more than 300 IT system houses across Germany. No external funding, subsidiaries, or M&A activity is disclosed; the business operates as a founder-owned sole proprietorship with no reported changes in ownership structure.
