About Wirkung+


About us - The "+" in Wirkung

Successul, happy sales peopleSales is a demanding, multi-layered, holistic composition - not just (as some critics think) "loud or quiet" or "you're either born with it, or not". If you have the right settings, you can noticeably improve your (sales) instruments and the resultant sound (i.e. outcome). This is exactly how we can make your business even more successful:

  • Wirkung Plus specialises in sales-centric business management and is clearly results-oriented
  • We work with our clients to identify the most effective growth levers in sales and implement them at all levels on the basis of resilient concepts
  • Our partners are small and medium-sized enterprises and corporations from more than 20 different industries - with one thing in common: they all want to clearly expand their market position
  • Our aim is to anchor sales as the decisive turnover and value driver in a company and help shape a profitable future

Our experience shows that you definitely can learn and improve sales. To a significant extent it is simply a question of the right inner attitude. Our competence team will help you carry out this demanding change process.

For more than ten years we have been one of the best addresses in this field. A mere coincidence? Find out for yourself! We look forward to hearing from you. Just call +49 40 235 13 08-0 or email s.hase(at)
