With passion and expertise we support our customers in their individual requirements. Our team of 15 specialists ranges from Amazon SEO and SEA experts to native speakers for every EU marketplace and photographers for optimal product photos. We use this bundled know-how to achieve our customers’ goals with high efficiency and in line with their needs.

We have been a member of the Thuringian nutrition network since December 2019.
We are pleased to actively support the food industry with our expertise in e-commerce, product development and special sales on Amazon.


As a member of the Success Factor Family network, we are also setting a visible sign that we are addressing the issue of compatibility between work and family. MadeByBrain has committed itself to a family-conscious working policy and is committed to ensure that team members can work independently of time and place.




The iPad cushion padRelax is the Maserati among the tablet holders. The high-quality, german- made cushion guarantees maximum comfort with secure support. The limitless choice of fabrics and colours allows each customer to create an individual design. Because we are convinced of our quality standards, we offer every buyer a lifetime guarantee.



sitzZ is your loyal companion at all sporty, dashing events. During a short break, lawn racers, park bench seaters, uphill climbers and football criers warm their butts on the warm sitzZ® – even on cold days. Neither wind nor wetness defies the robust cushion. Thanks to its foldable format and particularly light weight, it is always ready and waiting to be used.





Mastering the situation and seizing opportunities

Almost all retailers and manufacturers face major challenges in the pandemic year 2020.
As a newly baked partner agency in the Amazon Service Provider Network (SPN), we now have even more opportunities to accompany our customers in their personal success story as a vendor on Amazon and to actively support them in this difficult time.


Rising demand – rising supply

Whether a small food start-up or an internationally operating pharmaceutical group: our tailor-made solutions for manufacturers and retailers are in increasing demand. This is why we have strengthened our team and can now offer even more service and support. Innovative tools increase our productivity. We rely, among others, on Helium10, BidX, Sellics and Sellerboard.


Amazon workshops for manufacturers and retailers

Whether FBA, FBM, SPA or HSA: the world of Amazon seems complicated. We make it understandable. In our individual designed workshops, our customers have been developing their own recipe for success since 2017. From creating a sales account to optimised logistics processes to the ideal product description and profitable advertising on Amazon.


Our e-commerce and Amazon know-how as an agency service

One year after the change of name, a new chapter in the company’s history began: We are passing on our e-commerce know-how as an agency service. We have deliberately focused on Amazon, because this platform offers ideal terms and conditions to companies of all sizes to sell their own products successfully and profitably.


All under one roof

The agency “Das weiße Fenster” and padRelax UG (limited liability) have merged. Since January 2015, the agency and production have been operating under a new label: MadeByBrain. Nothing changes for our clients, but internally the course is set to prepare the company for an exciting future.


Own beginnings on Amazon

Only a short time after the foundation of padRelax UG (limited liability) it became clear: Our own online shop for the innovative tablet holder is only one of several distribution channels our customers use. So our journey began in early 2012 as a marketplace provider on Amazon. A completely new world from a provider’s perspective: Many great customers – but also numerous competitors.


Foundation of the padRelax UG (limited liability)

Apple has had a new product in its range for a few months now: the so-called iPad. This innovative device consists almost exclusively of a large display and offers the Internet at your fingertips. Anywhere and anytime. But on its own, the iPad quickly becomes uncomfortable. Lying flat on the table, the neck quickly tightens. Holding on tightly restricts your freedom of movement and makes your hands ache. Why has no one solved this problem yet? This is the story of padRelax.


The “white window” gets an adapted frame

After four eventful years, the co-founder is devoting herself to new challenges. But „Das weiße Fenster“ remains open. Only the framework is changing: the growing customer base places more emphasis on in-depth marketing consulting. To meet this need, Steffen Hartmann clearly focuses on consulting.


Founded as a classic advertising agency

In the meantime, our kick-off lies far behind: In 2003, Steffen Hartmann founded the Erfurt advertising agency “Das weiße Fenster” as a GbR together with a graphic designer. The first customers were provided with creative advertising material and contemporary websites. We have helped regional customers to take the step into the internet. We have developed and implemented marketing measures for and with our customers. And we have realized print works. Many print works.
