undconsorten evolved from the collaboration of experienced business consultants who have amassed more than forty years’ experience in strategic business consulting.

Since founding undconsorten in 2006, Dr. Jens Müller-Oerlinghausen, Dr. Axel Sauder and Dr. Axel Hüttmann have gathered a wealth of expertise in strategy development and implementation, HR topics as well as large reorganization and transformation processes. They also brought to the table their previous years of experience in consulting work for firms such as McKinsey & Company, among others.

Their shared enthusiasm for combining strategy and personnel topics led them to mutually create undconsorten. Today, they aspire to drive great consulting work while staying true to undconsorten’s unique consulting approach.



undconsorten thrives like the consulting carried out by our people. Our consultants have outstanding analytical abilities and are distinguished by their professionalism and strive towards excellence.

Some of our consultants come to us from renowned consulting firms as well as established companies and institutions. Others have started directly after university, with the right mix of qualifications, such as excellent degrees, internships and extracurricular activities.Most of our consultants have been with us for many years.

Our consultants are empathic and experienced individuals. They can understand, win over and develop a client’s employees, using more than mere logic to do so.

Finally, our consultants are people who have an eye for practical needs and requirements. They know the only good concept is one which has been put into effect, and they pitch in to make sure this gets done.


To ensure our exacting standards of quality are met, we maintain a highly qualified back office made up of a network of researchers, graphic artists, multimedia experts, copywriters and translators.

This office team allows our consultants to fully concentrate on the tasks and interests of their clients, therefore allowing them to be particularly productive.

If necessary, we bring in specialized reinforcements to ensure the interests of our clients are being met with the best possible performance. For this, we use our network and purposefully strengthen our knowledge of functional topics or consult with industry experts.

In this way, we always work together with specialized cooperation partners whenever this makes sense for the particular requirements of a client’s project.

From these beginnings, Jens built up the German and to some extent the European HR Practice at McKinsey & Company, which he led until 2005.
