Johanssen + Kretschmer (JK) was established in 2001. To this day, the consultancy for strategic communication and stakeholder management is owner-operated and independent.

From the start, JK has focused its consultancy on integrating various stakeholders’ perspectives. With a 40+ staff in Berlin, Frankfurt and Hamburg, we advise clients in the public sector and companies operating in changing regulatory environments such as energy, mobility, digital, health / pharma and media. Our unique stakeholder-centred approach aims to grow an organisation’s relations capital, and preserve and expand its respective strategic options. In almost 20 years of successful consultancy, we have accumulated a wealth of experience advising firms of all sizes.

Knowhow. Impact. Results.


We subscribe to a Code of Business applying equally to our staff and business partners. We firmly believe in the value of compliant, transparent consulting. JK is an original member of the German Association of Political Consultants (de’ge’pol), which advocates transparency in political consulting and a mandatory registry for political advisors.
