What Dierck Group does

Dierck Group GmbH is a family-owned German IT system house founded in 1973 and headquartered in Schwentinental near Kiel. The company delivers a comprehensive portfolio of managed IT services spanning 12 core categories — IT services and support, IT infrastructure, telecommunications, cloud services, data centers, IT security, hardware procurement, software applications, energy systems, print and office solutions, refrigeration and air conditioning, and consulting. Services are delivered through 10+ wholly-owned specialized subsidiaries including BMAnetworks, DIERCK Consulting (formerly hm-consult IT-Management GmbH), DIERCK Dynamic Voice, DIERCK Energiesysteme, DIERCK IT Systems, DIERCK Managed Print Services, Giller Kähler E-Technik, GORDION, and the recently acquired tanum consult GmbH, supported by the DIERCK Academy training division.

The group employs 260+ people across four regional offices in Kiel, Hamburg, Berlin, and Cologne (with a fifth Munich foothold via tanum consult). Its customer base spans SMBs, large enterprises, the German public sector, education, and justice/legal verticals. Revenue mechanics are diversified across subscription/managed services (IT support, cloud, security, data centers), hardware resale (infrastructure, telecommunications, energy systems, print), one-time software licensing, and professional services (consulting, training at EUR 185–1,975 per course). Go-to-market is direct, consultative, and field-led through regional offices, with marketing supported by the annual INNO IT trade fair, the InsightD TechTalk series, social media presence, and case-study content.

Ownership and leadership are entirely family-controlled: the managing directors are Wolfgang Ehrk, Fabian Ehrk, and Alisa Ehrk, with no external investors or public listing. The group's stated strategic posture emphasizes personal customer relationships, short decision paths, and one-stop-shop integration of IT services — positioning it as a regional system house with nationwide execution rather than a national platform vendor.
