I am Mario Šimunović


My name is Mario Šimunović, an architect of visions, a designer of dreams and a passionate technology and design enthusiast.

It was no coincidence, but a destiny that led me into the world of media design and media informatics. Even at a young age, I knew that my destiny lay in exploring and merging the fascinating worlds of technology and design. I have learned that when these two forces collide, the line between what is real and what is possible becomes blurred.

From that moment on, my journey became a continuous search for perfection and innovation. I have been dedicated to design since the age of 15 and my passion for moving images led me to my own YouTube channel, where I proudly look back on the production of over 160 videos.

My work is based on three pillars - excellence, creativity and authenticity. I strive for excellence in every project I tackle to ensure that every client goes to sleep happy at night. Creativity drives me to look beyond the obvious and find unique solutions. And authenticity is the key to providing each customer with an offer that is as unique as they are.
