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.
