EHM

What EHM does

EHM (e h m gmbh) is a privately held, family-owned electrical engineering services company headquartered in Witten, Germany, operating since 1976 and approaching its third generation of family ownership. The company employs more than 65 staff, including 8+ apprentices, and is supervised by the Handwerkskammer Dortmund under the legal form of a GmbH registered at AG Bochum (HRB 8788). EHM delivers full-service electrotechnical solutions — planning, assembly, maintenance, customer service, and IT services — across the technical fields of energy distribution, KNX bus technology, network technology, lighting technology, and security technology for commercial, industrial, institutional (healthcare, education), and private customers.

The company's service delivery is anchored by CENDAS, a proprietary cloud-based construction site management and project controlling platform (Centrales Datenarchivierungssystem) that the company markets as enabling up to 20% efficiency improvement in construction site coordination. CENDAS is now positioned as an independent software platform with its own web presence. A second product line, bioLogic Akademie, is an online professional education offering distributed via elopage.com. EHM also relies on DDS-CAD for electrical system planning documentation.

EHM's business model is project-based professional services revenue, with quote-based pricing for installation, maintenance, and IT contracts. Go-to-market is direct enterprise field sales combined with referral-based acquisition, primarily across North Rhine-Westphalia but with active project delivery across more than a dozen German cities. Notable customers include DSV, Amazon, Dachser, Ardex, Marien Hospital Witten, Mr. Wash, IntercityHotel, Swiss Life Asset Managers, and various schools. The company is ISO 9001:2015 certified (since 2018), recognized as a TOP 100 Innovator in 2020, holds the HWK Training Seal, and has earned six consecutive years of Creditreform creditworthiness certification placing it in the top 2% of German firms.
