High Five: What Flies and What Flops When Using AI to Craft and Scale Creatives

Hey, App Growth Community! Welcome back to High Five, our five-part mini-series spotlighting five of the boldest minds making the biggest waves in mobile marketing.

In this final episode, we’re ending on a high note with Michal Bubernik, Head of Marketing at Pixel Federation—the Slovakian studio behind beloved hits like TrainStation 2, Seaport, and Diggy’s Adventure. A creative force and industry veteran, Michal has helped shape Pixel’s reputation for simulation excellence and built a standout strategy that blends data-driven experimentation with human realness.

Joining host Peggy Anne Salz and series regular Peter Jung, Head of Paid UA & Creatives at App Guardians, Michal shares how AI is empowering his team to scale creative production without sacrificing quality—or soul. From the early days of static ad testing to fully automated video workflows and AI-generated voiceovers, Michal takes us behind the scenes on how his team went from brainstorming to blockbuster ads.

Tune in for honest insights and pragmatic tips, including when to let AI take the wheel, how to spot a winning creative early, and why sometimes the best-performing ads…aren’t the prettiest. (Spoiler: scrappy still sells.) Plus, don’t miss Michal’s backstory about how he became the “Tuna of the Gaming Industry.”

It’s the perfect finale to a series about fearless experimentation, fast iteration, and never losing sight of the human touch. Listen in now!
