Stamm

What Stamm does

STAMM GmbH, founded in 1991 and headquartered in Riesa, Saxony, is a private German limited-liability (GmbH) engineering services company specializing in the planning, installation, and maintenance of electrical, data, communication, and security technology systems. The firm operates across five integrated service lines — Elektrotechnik (electrical installations, lighting, photovoltaic, EV charging infrastructure), Datennetze (structured copper and fiber-optic cabling, server rooms, WLAN/VPN), Sicherheitstechnik (fire alarm systems, intrusion detection, video surveillance, digital access control), Kommunikationstechnik (telephone/VoIP, nurse call, door intercoms, electroacoustic and time systems), and Fernwartung (remote diagnostics and monitoring) — for industry, commerce, hospitals, and public institutions. Under Managing Director Dr.-Ing. Maik Stamm and Prokurist Stefan Hübler, the firm holds DIN 14675 certification for fire alarm work alongside a broad portfolio of DIN/DIN VDE/DGUV compliance credentials that are mandatory in regulated German B2B building-services procurement.

The company's technology stack is integration rather than proprietary: it deploys and configures third-party platforms from partners including SimonsVoss (digital locking), Axis Communications (video), Honeywell (fire/intrusion), Alcatel-Lucent/ALE (telephony), SMA and Fronius (PV inverters), Ackermann (nurse call), and NFON/Rainbow/3CX (cloud telephony and UC). Underlying technical depth is concentrated in certified field execution — AuS-qualified (under-voltage) workers, DGUV V3 testing, fiber fusion splicing and OTDR measurement, KNX building-automation integration, and DIN-compliant safety lighting planning — rather than in software IP.

Commercially, STAMM operates a regional B2B sales-led model with no e-commerce or self-serve digital channel; revenue is generated via custom project quotes for one-time installations (new build, modernization, renovation) plus recurring maintenance and inspection contracts (DGUV V3 testing, BMA/EMA servicing, remote monitoring). Customer acquisition runs through website contact forms, referrals, and direct field sales via offices in Riesa (HQ), Dresden, and Leipzig, with a reported 90% repeat-customer rate (STAMMKUNDEN) indicating strong project-driven stickiness. Reference clients include Rathaus Riesa, REWE Nossen, 16. Grundschule Dresden, ESF Elbe-Stahlwerke Feralpi, Elblandklinikum Riesa, Collm Klinik Oschatz, Einkaufszentrum RiesaPark, and Schmiedewerke Gröditz — concentrated in Saxony and spanning public, retail, healthcare, industrial, and education verticals. The firm employs 48 full-time staff plus 6 apprentices (12.5% of headcount in training).

Core offering

STAMM GmbH plans, installs, and maintains electrical, data, security, and communication infrastructure for commercial, industrial, healthcare, and public-sector clients across Saxony. Core service lines are Elektrotechnik (electrical installations, lighting, PV, EV charging), Datennetze (structured copper and fiber optic networks), Sicherheitstechnik (fire, intrusion, video, access control), Kommunikationstechnik (telephony, nurse call, intercom, ELA), and Fernwartung (remote monitoring and maintenance).

Product overview

STAMM GmbH is an electrical, data, and security engineering company offering five integrated core service areas: Elektrotechnik (electrical installation), Datennetze (data networks), Sicherheitstechnik (security technology), Kommunikationstechnik (communication systems), and Fernwartung (remote maintenance). The company operates as a unified service portfolio rather than a software product platform, providing complete installation, maintenance, and testing services. The electrical division includes lighting technology, safety lighting, EV charging infrastructure, and photovoltaic systems. Data networks encompass structured cabling (copper/fiber), server room infrastructure, and WLAN/VPN solutions. Security offerings cover fire alarm systems, intrusion detection, video surveillance, and digital access control. Communication services include telephone systems, nurse call systems, door intercoms, electroacoustic systems, and time synchronization. Remote maintenance enables continuous system monitoring and diagnostics.
