Ralf Renner

Ralf Renner

Managing Director

Ralf is extremely structured. His days and weeks take their course only according to a system. His dog Frieda can tell you a thing or two about it, because she usually experiences this very closely in the office. For example when Ralf drinks coffee by the gallon while being engrossed in writing newsletters and blogs. Or when he reliably sorts the meat out that Frieda loves so much. And when he always keeps track of everything and shows off his knowledge that it beggars all descriptions.

He is the master of words and the leader of our content team. As the expert for advertisement, communication and marketing, he takes the responsibility for all contents, the keyword research, A+ detail pages and your brand store.

Get in touch with Ralf if you want to:

  • optimise your product representation on Amazon,
  • push forward new products fast to page 1 and optimise the ranking,
  • implement a review and customer request management with fast reactions.
Stephan Stoppok

Stephan Stoppok

Managing Director

Caution, ideas are coming! If one strikes, then there is no holding back. For Stephan enforces strategically what comes to his mind. Even though he is on fire for his business, he never leaves scorched earth behind. He is far too social and charming. However, sitting is not his favourite activity, as he completes meetings like endurance runs. Stephan has unbelievably much power. That is to say he consumes canned energy. Plenty of it!

For almost 20 years Stephan sells his products on Amazon. As marketing expert he knows the stationary trade as well as the Amazon universe in every sense.

Get in touch with Stephan if you:

  • need a sparring partner for strategies and ideas for your Amazon-business,
  • like ideas that are thought outside the box and that fire your online business,
  • would like to have your Amazon analysed in order to identify potentials.
Nanette Böhme

Nanette Böhme

Operational Management

She has got the travel bug and loves to espy new beautiful destinations. However, in our firm she is usually busy searching. In fact searching for solutions of all tasks and challenges that arise in working life. And she is finding them and working consequently in our projects on brilliant solutions. Always! For our customers and our team … from the beginning on. She will find the golden thread for the boss if he has lost it once again. Actually, she is our fairy godmother who is never aloof.

Her welcome page is “Dispute Management” on Vendor . She knows listing sheets from column A to XX by heart and almost all members of Amazon Support by name.

Get in touch with Nanette if you:

  • despair once again of Amazon-Support,
  • have the feeling that the compensation payments to Amazon almost exceed your turnover,
  • your products on the Amazon website do not look the way you wish.
Kathleen Wagner

Kathleen Wagner


She knows the score and what to do about it. With a charming smile, eloquence and candour, she hits the nail on the head. This fascinates especially men immensely. And it produces a positive atmosphere which is important to her. For all the stress. For anything else, there is alternative medicine. Kathleen is our heart and soul with the extraordinary talent of juggling numbers.

Kathleen maybe understands Amazons accounting better than Amazon itself. She is master of hundreds of thousands posting records, knows every outstanding bill and painstakingly enforces every cent from Amazon.

Get in touch with Kathleen if :

  • VRET, SCR, DA, VIR, LWA or APP is just scrambled text for you,
  • invoice cuttings by Amazon are on the daily agenda of your accounting,
  • you are looking for automation solutions for your Amazon accounting.
Matthias Walther

Matthias Walther

Project Management

From the very beginning, Matthias has been our perfectionist for every occasion: he is funny, pursues a straight line and reaches the goal easily. That’s where he wants to go, because he is already at Z when A is not even announced. Using all numbers and excel tricks of this world, together with peace of mind. That’s where he regains his strength. We love all of this.

With strong analytical skills, Matthias manages our projects. His field is, for instance, planning lightning deals, special deals as well as coupons and competition analysis. He is our expert for direct fulfilment (drop shipping) and direct import (FOB).

Get in touch with Matthias if you:

  • require a competition analysis of your competitors on Amazon,
  • are not sure which sales campaign is the right one for you at the moment,
  • would like to know to what extent drop shipping or direct import can be profitable for you.
Daniela Hartmann

Daniela Hartmann

Amazon Order-Management

Cool outfits, eloquent and congenial – Voilá, Daniela! She is always well received. Because she tackles issues strong-willed and heartily. And she knows that she gets on best with remaining calm. Sometimes even in her cabriolet. Steadily smiling, she precisely manoeuvres through the traffic. Always stays on her lane. Even if she imagines to cruise towards the sun and the sea. Yes, this is Daniela. In real life and in our company. Honestly!

Daniela is expert for operative tasks and knows the Amazon supply chain off pat. Even at 3 o’clock in the night, she is able to recite ASIN, PO, ARN and ASN. Above all she manages the whole delivery process of our customers: from single packets to pallets up to whole containers.

Get in touch with Daniela if you:

  • want to optimize your supply chain to Amazon warehouses,
  • have questions on the right labelling of products,
  • need support for Amazon Order-Management.
Gunnar Gläser

Gunnar Gläser

Data Engineer

What he does, makes sense. Having an eye for details, he is looking critically for solutions. His motto: 0 and 1 are important, but there is more to it. For Gunnar is not only IT expert, but also very creative and communicative. Being well organised, he uses this talent in a manifold manner. A role that isn’t everybody’s job. He, however, masters his role perfectly. In our company — a sight to behold.

He brings out every byte from ARA Basic or ARA Premium and even knows the last lost item. Furthermore, Gunnar is fit in cracking the Amazon algorithm.

Get in touch with Gunnar if:

  • the Amazon reporting tools ARA Basic or ARA Premium are too confusing for you,
  • you want to know how to collect and aggregate Amazon data effectivly,
  • you need support in the automation of your order management via EDI.
Felix Jähn

Felix Jähn


Is this already art or do you still doodle a little bit? Felix has got talent and yet quietly and unnoticed comes around the corner presenting smashers. Always polite and with music on his ears which he needs for his concentration. But caution, please don’t take him for someone else – he is not the DJ and music producer. That is not what he wants to be. He is sure of that. And we like that because here is where the action is.

Later, he may tell his grandchildren that he was one of the first e-commerce traders ever to be seen.

Get in touch with Felix if:

  • you want to know why it is great to train in our company,
  • you want to know what an e-commerce trader learns in his apprenticeship,
  • you are interested in an apprenticeship at our company.

We are looking for you!
