The Clintworld Team


Wolfgang Klotzki

Wolfgang Klotzki is a co-founder of Clintworld. His focus is on managing a sustainable company growth whilst maintaining first class quality.

After obtaining a maths and economics degree from University of Hamburg, Wolfgang joined Talkline GmbH and became head of pricing and business intelligence. In 1997 he co-founded solution42 that was acquired by Portal Software in 2000.

Wolfgang appreciates Clintworld’s international activities and considers every travel as an opportunity to appreciate at least a small insight into other countries’ cultural and geographical wealths.

He also reflects the value of long-term relationships by maintaining affection to Hamburg’s continuously unsuccessful football club HSV.

A lot of things in Clintworld revolve around our software “Clintview”. The heart of the company is and will remain its employees. In order to maintain and maintain long-term business relationships based on trusting cooperation, employees are needed who are able to live and transport exactly this philosophy. Therefore, we are proud of the fact that the average length of service is > 10 years.

A large number of the employees have already worked together at Solution42, the predecessor company of Clintworld, and thus each have more than 20 years of experience in the billing and pricing environment. Over the years, this core of employees has been selectively and specifically expanded to include colleagues with extensive experience in the telco industry and new qualifications, complete skills in the areas of advanced analytics and development.

We are convinced that “Strong delegation of responsibilities in a very flat organisational structure lead autonomous thinking and acting- while keeping a strong team-spirit” is the best way to ensure that the team members complement and enrich each other.

Looking to the future, Cintworld also attaches great importance to the recruitment and internal development of perspectives, which enrich the company with new impulses, approaches and perspectives. Therefore, we maintain a long-term cooperation with FH Wedel, whose students are offered practical training at Clintworld”.

Lars Bitterling
Senior Consultant

With new ideas coming in continuously from the customer Lars isn’t bored having a focus on this important customer for a long time. He is one of the few colleagues coming to the office by bike, some quality time he devotes neither to his family nor to Clintworld.

Dirk Schmidt
Senior Consultant

With his background of elementary Particle physics Dirk is used to take a look at details while continuing to see the big picture.
Therefore for Clintworld is often sent to projects in the early stages when it is all about time to market and pragmatic solutions while not neglecting quality and precision. Due to his passion for good (and bad) films Dirk can be challenged to quote some really strange scenes and dialogues.
