Stefan Grewe
Sales Director Telecommunications Germany & Switzerland, Sennheiser Vertrieb und Service GmbH & Co. KG

At Sennheiser, we had already some experience with training institutes and sales specialists… With our competent “companions” at Wirkung Plus we have now, however, reached a new level: Demanding. Inspiring. Effective. With the right touch of humor. It suits perfectly!

Leif-Erik Lindner
Business Director Consumer Electronics AV, Samsung Electronics GmbH

Very pragmatic and close to our daily business. Everybody could take away important aspects for his day-to-day business. Really good work. Keep it up…

Florian Lamisch
Head of Technical Solution Design & Coordination, T-Systems International GmbH

Global IT investments are quickly extending into high 7-figure sums. A high workload and the highest demands on our team require precise and optimally efficient training courses which can be realised pragmatically. Michael Blohm has more than satisfied these requirements. Following 4 intensive sequences, I can personally recommend the work of Wirkung Plus at any…

Wolfgang F. Kochan

Just like many other suppliers of up-market capital goods, we need to have a “foot in the door” and a secure base when closing a deal. We rely on the expertise of Wirkung Plus, especially when it comes to these difficult issues. I am especially impressed by the rare mix of a clear structure and…

Lothar Stanka
Head of Sales Business Clients, Süwag Energie AG

The liberalisation of the energy market has had significant consequences in the area of sales. Apart from the required structural adaptation of internal processes, the primary objective here is the systematic training, support and sales management of our approximately 40 energy managers. In this, we have relied on the know-how of the entire Wirkung-Plus team…

Thomas Braune
Sales Director, Fronius Deutschland GmbH

You have put our individual requirements into really professional activities. No matter whether the topic was market orientation, conduct of negotiation, or the positioning of our technical sales force. This is how change works!

Alfred Schillert
Managing Director, PROvendis GmbH

Our demanding negotiating situations with inventors, universities and companies require individual behavioral strategies. With Stefan Hase and Michael Blohm, we were able to translate our concrete requirements into practical solutions. This has been an important milestone for our committee of experts. And all of that was constructive, pragmatic, and target-oriented!

Peter van Teeseling

With his ideas about upcoming trends, the “future of sales” and the required toolsets, he hit exactly the nerve of our…

Prof. Dr. Roland Hüttl

I make it short: professional support – individual approach – effective results. Or a little longer: we are working always happily together with the team around Stefan Hase and Michael Blohm!

For the work done in connection with the restructuring and development of our sales department, I’d like to say a big thank you.

Also for us, as one of the world’s largest copper producers, the market changes significantly. Within the last 2 years, we have cooperated with Wirkung Plus.

Channel Manager – Professional Print, Canon Deutschland GmbH

In the graphics art unit, we had one of the most successful years. We accomplished this remarkable performance to a high degree through a top trade fair performance of the entire team.

Ulrich Kothe
Sales Manager, Albany Door Systems GmbH

Really good sales coaches who know what they’re talking about, can put across their topics in an enthralling way, and practice what they preach are rare indeed. And that’s why I’m so glad to have discovered Wirkung Plus. The events we organised with you met all our requirements. I cannot express my ap-preciation too highly.…

We systematically trained our Americas sales team with respect to new demands of the market. Both in workshops (here in Houston, USA) and in the field: New York, Brazil and Peru.

Jörg Bilz
Head of Sales, Programm + Datenservice GmbH

Having our staff professionally trained with a practical focus gives us, as producers of high-quality software, a major competitive advantage. The fact that we have set up our own PDS Academy reflects that just as much as the care we take in selecting our strategic training partners. We have been working very constructively with Wirkung…
