Business development and a new strategy

“In Petra we found a consistent and target-oriented person who helped us to narrow down our services. She was critical in the growth of our digital and social media presence. Her unique experience and expertise with such media was a critical factor for our customer growth.

Without a doubt, I can recommend Petra. She applied the growth which she has driven in the startup scene to our business with great success. We have Petra to thank for the positive growth which our company has seen in the past five years.”
