Based in Koenigswinter, Germany, IMS Interim Management Solutions was founded in 1996 by Dr. Harald Wachenfeld.


Since its foundation, IMS Interim Management Solutions has established scores of national and international alliances and partnerships. The company has also set up an Interim Management Network, which it continuously updates.

IXPA – International Executive Provider AllianceIMS is founder and Partner Germany of IXPA International Executive Provider Alliance. Visit for details.

If we do not find the right interim manager for you from our own pool, we can tap the network’s pool. As a result, we have always been able to identify and recommend at least one qualified candidate for every assignment inquiry we have received to date – and this has been the case even in light of the broad range of requested soft skills and highly specialized product, market and technical expertise.

We also have alliances with other companies in Germany and abroad. These companies are active in the areas of management consulting, M&As, venture capital, private equity, corporate investment management, outplacement, bankruptcy administration and business development.

They make referrals to IMS when they hear that qualified interim managers are needed. This is because our exclusive focus on interim management does not threaten their business, but rather complements it. Conversely, we are also happy to place you in direct contact with our partner companies and their specific range of services.
