Nikolina Simić

Web Analytics Specialist

Nikolina Simić

Web Analytics Specialist

Meet Nikolina – our Web Analytics Specialist who also dabbles in PPC like it’s no big deal (but it kind of is). She’s the one you want on your team when you need data to actually make sense. Her reports? Flawless. Her attention to detail? Unmatched. She somehow manages to be incredibly thorough and effortlessly cool at the same time.

Always stylish and always on the go, Nikolina is just as likely to be spotted exploring a new country as she is diving deep into a Google Analytics rabbit hole. And no matter how complex the task, she handles it with the calm of someone who’s got it all under control. Unsurprisingly, she’s on the most wanted list when it comes to our sync meetings.

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 🙌

Luka Stefanović

Head of Web Analytics

Luka Stefanović

Head of Web Analytics

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!

Jovana Božić

Head of CRO

Jovana brings a rare blend of structure and empathy to everything she does. With a Bachelor’s in Psychology and a Master’s in Marketing and PR, she’s both detail-oriented and deeply human-centric—qualities that make her a natural at crafting thoughtful, creative ads that truly resonate.

She’s the one you can count on for well-researched ideas, polished copy, and keeping things organized behind the scenes. And as someone currently studying to become a psychotherapist, her calm presence and people-first mindset shine through in every client call and team meeting.

Milica Terzić

CRO Copywriter

Milica Terzić

CRO Copywriter

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

Web Designer

Luka always knows just the thing—whether it’s an old movie you’ve never heard of but will love, a hidden-gem travel spot, or a surprisingly effective workout routine.

He’s a huge fan of vintage cinema, and when he’s not busy designing or exploring web design and site security, he’s usually being climbed on by his cat Nala, who’s made his chair her personal throne during meetings.

A true morning person, Luka brings a steady, relaxed energy to the team. He’s fun to be around, always ready with a perfectly timed sarcastic comment that makes the whole call a little lighter.

Ivana Babić

Project Manager & Scrum Master

Ivana Babić

Project Manager & Scrum Master

Ivana is on the finish line of getting her Bachelor’s Degree in Project Management—and she’s already putting those skills to work every day. Based in sunny Dubai, she leads projects with impressive precision by day, and transforms into an amazing UGC content creator by night.

Creative, proactive, and full of ideas, Ivana pours passion into everything she does—whether it’s managing timelines or crafting scroll-stopping content. She also loves spending time outdoors, hiking, or exploring new destinations whenever she gets the chance.

As a kid, Ivana was a bit of a magnet for scrapes and bruises—often thanks to her older brother’s “creative” ideas. These days, they work together in perfect synergy. ☯

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

Igor Babić

Founder and CEO

You might wonder what a cheerful guy in an oversized shirt is doing as a CEO.
We wondered the same—until we saw him in action.

Igor is full of energy, always juggling ten things at once, and somehow doing them all well. He’s a passionate PPC strategist whose eyes light up the moment he starts talking about performance and big-picture ideas. Clients love him for his clear, thoughtful explanations and the genuine care he brings to every project.

When he’s not deep in campaign strategy, you’ll find him racing Formula 1 tracks in full VR mode or whipping up something delicious for lunch—with his cat Tokyo nearby, probably trying to steal a bite.
