The beginning of a success story
In 2013, with nothing but a vision, a couch as an office and a starting capital of just 20 euros for the business registration, the extraordinary journey of nextlevels began. Paul Kalisch and Slawa Ditzel, two ambitious minds with a shared passion for the digital, decided to push the boundaries of what's possible. They wanted to help companies succeed in the digital world. From the very beginning, nextlevels stood out for its strong drive to innovate and its ability to deliver creative and technologically advanced solutions. Founding the company from the couch symbolizes not only humble beginnings but also the founders' unwavering belief in their idea and their ability to achieve maximum results with minimal resources.
