DDIM

What DDIM does

DDIM – Dachgesellschaft Deutsches Interim Management e.V. is Germany's leading professional association for interim management, founded in conjunction with the launch of its annual congress in 2003 and headquartered at Lindenstr. 14, Cologne. The organization is a registered association (e.V.) under German law, owned and governed by its members, with a 5-person board chaired by Dr. Marei Strack and an employee base of 501-1,000. It serves four constituencies: individual interim managers seeking visibility and project flow, enterprises seeking temporary executive leadership, interim management provider firms, and law firms specializing in restructuring and turnaround matters.

The association's core products are structured around six program lines. (1) The DDIM.kongress, held annually in Düsseldorf since 2003, draws 400+ participants and 30+ exhibitors and is the flagship member-acquisition and revenue event. (2) Eighteen DDIM.fachgruppen organize knowledge exchange across Automotive, Defence & Aerospace, Digitale Transformation & KI, Energy, Finance, Food, HR, International, Communication, Life Sciences & Healthcare, Sustainability, Operations, Procurement, Project & Program Management, Process Management, Restructuring & Transformation, Startup & Scale-up, and Sales/Marketing/Service. (3) The managerportal.ddim.de member portal provides a public-facing directory, member login, profile management, and project inquiry routing. (4) DDIM.regional, DDIM.lokal, and DDIM.virtuell events run year-round across 10+ German cities plus virtual sessions. (5) DDIM.wissen delivers certificate programs in partnership with RWTH Aachen (FIR), SRH Heidelberg (IfUS), and EBS Executive School, covering topics from Digital Product Management to Transformation/Turnaround Management and ESG Implementation. (6) The Interim Management Excellence Award, the quarterly DDIM.reporter newsletter, and the INIMA international network round out the offering. Underlying technology is conventional: a custom web portal, Zoom for virtual events, email/newsletter distribution, and standard social media channels (LinkedIn, XING, X, YouTube).

DDIM's revenue model is membership-fee driven, supplemented by congress sponsorships, exhibitor fees, and associated-company contributions. The organization is a non-profit and does not publicly disclose financial metrics. Geographic reach is primarily Germany with growing European extension through INIMA, including hosting the 2025 IIMC in Cologne with 11 country delegations. Public affairs activity, particularly around StaRUG-related frameworks presented by associated law firms, represents the association's regulatory positioning strategy.
