We are absolutely thrilled by this fantastic feedback! A huge thank you to Bielefeld Marketing GmbH and Christina Makowski for their trust and great appreciation of our work.  

  The collaboration with the team has been consistently positive: appreciative, solution-oriented, and always swift in development and implementation. Particularly noteworthy are our team's creativity, quick accessibility, and efficient problem-solving.  

The results speak for themselves: The BielefeldJETZT App impresses with intuitive operation, successful design, and top performance. And the integrated tap.rating solution? Extremely well-executed, cleverly differentiated, helpful, and incredibly easy to use! It will elevate the evaluation of future events to a new level. 

This praise truly motivates us! We are incredibly excited about our continued long-term cooperation and upcoming exciting events like the Sparrenburgfest 2025 (July 25-27), where our solutions will once again be put to use.
