Who we are

Behind the lab:
our mission & vision

At MGL, we don’t believe in hype or empty promises—just real, measurable growth.
I’m Ivan Maksimović, the founder and Growth Marketer of MGL. What started as a solo journey in freelancing and running successful eCommerce projects in the U.S. has evolved into a global agency driven by one core belief: exceptional service isn’t optional—it’s a responsibility.
Based in Belgrade, Serbia, our team of passionate marketers collaborates with businesses across the U.S., Europe, Australia, and beyond. We don’t just run Meta ads; we build partnerships rooted in trust, strategy, and a relentless pursuit of results.
For us, advertising is more than just numbers—it’s about impact. It’s about helping businesses unlock their full potential through data-driven strategies, creative excellence, and a commitment to authenticity in an industry that often falls short.
At MGL, your success is our success. And that’s what drives everything we do.
