Our history...

Our values and roots..
In 2009, two brothers: Karol and Wojtek, decided to quit their job and start their venture - they founded our agency. From the very beginning, the most important thing for us was to help SMEs by delivering outstanding quality and service at affordable prices. We knew the only way to do it was to have a special connection of great people and the most effective technology. That's why we are a mix of professionals, excellent company culture, and top-notch technology.
