“Our Dream is to make teasing a way of living”

We tease our friends at school, we tease the girl or the boy we fall in love with, we tease the professor at the class, we get teased if our team loses, or if we take the wrong guess at a silly game. It’s the way we have fun with our friends, with our bestfriends or even with strangers. Teasing is the recipe that makes our lives joyful and spontaneous! Why? Because teasing is pure Fun.

Have you ever wondered why we are more miserable as we grow old and more happy when we remember our younger ages? Because we stop doing things we did younger and yes teasing is one of them. It’s not just an act, it’s a way of thinking and a way of living. A much more authentic and real one. So go on, start teasing like there’s no tomorrow and have fun, true Fun.

We believe that teasing is something much deeper than a “childish” game.

Designer & Developer

Being raised in a family that art and computers were the center of attention, he had the opportunity to explore both worlds at an early age. He started working as a computer technician and SQL developer while studying for his BSc degree in the American College of Greece. Fortunately, color, sketch, animation and design were inscribed in his DNA. The result, of combining art and programming, was an MA in computer animation and special effects at the University of Bradford. In 2007, he started working as a 3D generalist, graphic designer and flash developer. From 2009 he works as a freelancer. In June 2013 he co-founded tizU with his cousin, Apostolis.

Business & Marketing

It was during his studies at Athens University of Economics and Business that Apostolis was charmed from the world of Marketing. Thus, while still in university he won two student competitions and since 2008 he has been working on Retail, Digital Marketing, Branding and Social Media projects, acquiring valuable experience. In 2013, he decided to “dive” into entrepreneurship's world, as he believes that there is nothing more challenging than building a brand from zero. So, in January 2013, he co-founded Pinobo, his 1st startup which made him learn a lot about startups and in June 2013 he co- founded tizU. Since then he has been working in full dedication to make tizU a great app, alongside with his cousin - and partner- Spiros.
