Luka Stefanović

Web Analytics Specialist

Luka Stefanović

Web Analytics Specialist

Luka is working hard to grab his Bachelor’s Degree in Informatics and fulfill his dreams of becoming a programmer one day. His favorite downtime activity and partner at work is – the computer! Also, let’s not call this a coffee break but a fancy Irish whiskey break because that’s Luka’s favorite beverage. He likes the outdoors (especially when it’s cold) so much that his interest goes outside of this world and into outer space. So, we expect to see Luka doing something related to astronomy quite soon. Meanwhile, he’s slaying his internship at Diligent with the support of his childhood friend and our awesome colleague – Luka Banović!

Aleksandar Šaljić

Web Analytics Specialist

Aleksandar is one of our diligent team of specialists in the Web Analytics department. Before doing WA & Conversion Tracking, he worked in a bar but also owned a bar! He even worked on TV. Hello, multiskills! He exercises every day and eats boiled chicken and rice (even though he dislikes them both). We praise this type of discipline and dedication – it’s genuinely virtuous! He’s the same with his work, crunching up numbers & analytics stats 📊 Aleksandar loves reading and challenging his perspective through reading and watching movies. Such a wholesome dude 🙌

Jovana Božić

Head of CRO

Jovana Božić

Head of CRO

Jovana is the angel child of the office. We barely notice her, because she is so quiet and task focused.

In her free time you can find her watching Marvel movies and drinking dark beer.

There is nothing juicy to write about Jovana. Seriously.

God bless her soul.

Milica Terzić

CRO Content Team Leader

Milica is truly the Mother of Authenticity. She pours her heart and soul into everything she does.

You can see her eyes start to sparkle with joy whenever she gets a task to do research. And then she transforms into a busy bee and nails that research so hard!✨

Milica has seven tattoos. One of the freshest ones is a red dragon on her arm. And oh boy, she gets asked about the tattoo artist, like, a lot. She doesn’t mind. Just vibin’.

She also loves analog photography. Her Instagram profile looks like an exquisite art gallery of beautiful retro motives.

Luka Nikolić

Head of Design

Luka Nikolić

Head of Design

Luka is the Del Boy to Rastko’s Rodney. A hipster version of Del Boy of course. They’ve been best friends for 7 years now. (Not sure which one of them broke a mirror seven years ago).

When they’re not hanging out, they are playing Super Smash Bros. Luka thinks he is the best Little Mac player there is, but Rastko claims he will never beat his Jigglypuff.

He is a very silent soul until somebody sets him off or we’re playing a game where he has to keep quiet.

Known for always giving the best advice, but nobody ever listens to him. When it turns out he was right, you won’t ever hear him say ‘I told you so’.

Ivana Babić

Project Manager & Scrum Master

Ivana is on the finish line of getting a Bachelor’s Degree in Project Management. Besides that, she’s completed several interior design courses, which is why family and friends often turn to her for advice, help, or ideas regarding their home upgrades.

Ivana also enjoys spending time outside, in nature, hiking, or traveling abroad.

When she was a kid, Ivana constantly fell and got injured, leaving her with a couple of scars. But, points out she’s not the only one to blame – her older brother had creative ideas that often led to these mishaps.

Luckily today, they work in perfect synergy. ☯

Miloš Radanović

Chief Financial Officer

Miloš Radanović

Chief Financial Officer

Our sole mission is to keep Miloš happy.

When we played a game called Mafia, nobody dared to kill him. You wouldn’t want to enrage the person who signs your paycheck, right? (But on the other hand, our CEO Igor was killed every time. Definitely something to think about).

Miloš has a brilliant detective mind. During the game, he went all Hercule Poirot on us and figured out who’s Mafia every time.

His archenemies are office printer and paper drill. He is so easily spooked, and that means that working in the same office with him is always super fun. Also, he’s an inexhaustible source of funny Youtube videos.

Igor Babić

Founder and CEO

You might wonder what is a guy in his twenties wearing an oversized shirt doing at the position of CEO right?

We wondered the same thing – but those looks truly deceive.

What you don’t know is that Igor is a huge fan of “House of Cards”, is terrified of horror movies and completely obsessed with Formula 1.

If you ever catch him looking off into the distance, it’s either because he’s hungry or thinking of new PPC tricks.

PPC tricks that help your business grow digitally.
