The collaboration began in November 2019 for the support of the Amazon marketplace, an online multi-channel strategy was developed relatively quickly, and today IN & Out House GmbH sells on over 20 online marketplaces in Europe.

I am delighted to be working with Tobias Dziuba.
He is absolutely competent and his know-how has allowed our turnover to grow strongly. His advertising campaigns are not only very well created, but also controlled. This means that the advertising budget is always checked for efficiency.
He is always available and always ready to help. That's how service should be.

Takeover of all eCommerce activities of RICHEN in Germany and internationalization of the brand

IN & OUT HOUSE GmbH primarily manufactures furnishings such as electric fireplaces and shower cubicles under the brand names RICHEN, Kingstar, Wellbad and CrownFlame. The RICHEN electric fireplaces are particularly successful and are category leaders in several marketplaces such as Amazon.de, Amazon.it and Otto.de. Our cooperation consists of many different aspects, such as the creation of our own online store Elektrokaminshop.comThe management of seller accounts on various marketplaces, or the creation and management of Google Shopping campaigns.

Period of cooperation: Q4 2019 - ongoing

Takeover of e-commerce activities

Today, IN & OUT HOUSE GmbH operates successfully on several marketplaces. Since we took over the e-commerce activities for brands such as RICHEN, new markets have been opened up, marketplaces conquered and category leaders formed on highly competitive platforms such as Amazon.de, Amazon.it and Otto.de. Richen is also present on other marketplaces such as Real.de, eBay.de, Mediamarkt.de and Metro.de. Together with the holistic sales concept, which relies on targeted PPC ads on several entities, the chosen path has proven to be a complete success.

Optimization and development of products

By successfully managing Amazon Ads, Richen reaches a wide range of customers. Thanks to optimized advertising campaigns, Richen achieves high performance at all times and establishes new products. As a result, products such as the Richen electric fireplaces have long been among the top sellers in their category. 


There is no reason why universally used products such as electric fireplaces cannot also be sold in other countries outside Germany. It was therefore obvious to push ahead with the internationalization of the product range. One example of this is the successful development of the Italian market with the help of Amazon.it.

Advertising campaigns on Google Shopping and Otto.de

Suitable advertising measures can be used to reach new customer groups and undecided customers. We therefore take on advertising campaigns on Google Shopping and Otto.de in order to increase both reach and sales

Management of the Amazon.de Seller Account

"Amazon offers companies the opportunity to participate in e-commerce even without a separate online store. A simple product listing is no longer enough to be successful on Amazon. The competition on Amazon is fierce. With my core expertiseThe optimization of seller accounts including the revision of listings with A+ content, brand registration, optimization of titles etc. as well as continuous market observation have made RICHEN's products market leaders in their segment. The brand store we created also contributed to this.

Amazon trademark application

Registering a trademark on Amazon has several advantages. Firstly, it clearly defines the owner of a brand, and secondly, it opens up a range of options for researching imitators and subsequently removing affected listings. It also makes it possible to create a brand store. This is why trademark registration on Amazon is a must for us.

Creation of an online store

In addition to selling on Amazon, we have decided to launch our own online store. With Elektrokaminshop.com, we have developed a niche store for RICHEN, other reliable, and independent marketplace. The store is search engine optimized and user-friendly.
