Brand Growth Inspiration

Hi, my name is Valerie Dichtl.

I am the founder and owner of the Marketplace Uni.


The idea to found the Marketplace Uni arose during my time as a marketplace consultant. As a consultant, I got to know many brands from the industry that I advised on strategic and operational topics in the marketplace business and set up a concept for them. However, every time when I finished a consulting project, I took my knowledge back with me. My clients by then knew their strategy, but usually didn't have the staff and know-how to easily implement the strategy themselves. This was when I asked myself how I could help brands build their strategies and knowledge of online marketplaces themselves indepently of external consultants.


Up until then, I had worked for brands like Bogner and Skiny in online sales, and for the marketplace giant Amazon in fashion procurement. At Amazon I learned from scratch what it means to work for one of the biggest online stores in the world and got important insights into many different brands. 

With Skiny and with many other brands after that, I was co-responsible for building their marketplace business on Amazon, Zalando, About you and Co. I have worked on both sides of the marketplace business - the brand side and the marketplace side, giving me a 360° view on the topic and the ability to understand the challenges and potentials of all parties involved.


In addition, I found out through many conversations that many brands that want to sell their products via marketplaces lack the necessary knowledge, resources and capacities to get started. This was the crucial impulse for me to found the Marketplace Uni.


There is simply much more knowledge to be shared about marketplaces to allow brands to generate additional sales even more easily, and to leverage the potential to be available wherever your customers want to buy your products.

I participated in the program to deepen my knowledge because I would like to specialize in this direction. I particularly liked the extensive topic blocks. We learned a bit of everything. I also liked the fact that we were always given the recordings and minutes so that we could refer to them if necessary. I would recommend the program to those who want to expand their knowledge in a "short" time and become more confident in dealing with marketplaces.

I took part in the program because I had a lack of knowledge about the marketplace business. I liked the exchange with other participants from other companies. The program gives a good overview for beginners / newcomers to the topic and is certainly a good basis for taking the first steps and planning the right set-up for the respective company.

So far, I have been able to gain some experience with the Amazon.de marketplace. For me, it was therefore super exciting to gain knowledge about other marketplaces and to be able to make informed decisions about whether selling on other marketplaces will be profitable. What I liked about the program was that all appointments were live and that one had the possibility to ask questions directly or to dive deeper into certain topics. I also found it great that there were always assignments and you were thus "forced" to actively participate and could exchange ideas with the other participants. The course really does provide all the important content you need to get started in the marketplace business and avoid the classic stumbling blocks in advance. The content is presented in a great way and can be accessed afterwards. Together with the expert panels, the Marketplace Uni covers all content in remarkable depth.

Hi, my name is Jan Ollig. I am a trainer at Marketplace Uni.

I originally come from a multi-channel retail background, which is one of the reasons why I am quite familiar with the challenges of brick-and-mortar businesses in e-commerce. Over the years, I specialized in pricing and later worked as a consultant to help retail companies set their prices in an automated and algorithm-driven way.

Being experimental by nature, I discovered the marketplace business for myself a good five years ago. It all started as an Amazon Seller for black men's socks, which quickly became a top seller. After a few years, I started selling books on Amazon, which I wrote as a co-author during a trip around the world. The latter, by the way, was the inspiration for founding my current Amazon Marketing Agency. Nowadays my daily job is to help brands advertise their products (PPC Ads) on Amazon, thus harnessing the power of the marketplace for themselves and increasing their online sales. As a trainer for Marketplace Uni, I would like to pass on the knowledge that I have gained over the years about the marketplace business and look forward to welcoming you to one of our courses in the near future.
