Founded in Hamburg upon nordic values...

...and developed into an iternational research and consultancy company.


The company was founded by Hartmut Keller. His approach: HKM opens doors. Through fieldwork for American and British market research institutes HKM provides valuable information on the German market in order to support international companies effectively in their marketing activities.


Saw the business takeover by Thomas Braun. HKM becomes an international market research and consulting company. The fulfilled claim: A project only went well if it has given our clients an effective stimulus for improvement measures.
