A relentlessly ambitious creative director working at the intersection of innovation, storytelling, and strategy.
Bert Marissen is a Dutch Group Creative Director based in Los Angeles. Currently playing at TBWA\Chiat\Day.
I'm known as a relentlessly ambitious creative director, some might say delusional, with an unapologetically high creative bar and a deep passion for building brands and new business. I thrive at the intersection of innovation, storytelling, and strategy, constantly pushing the boundaries of what's possible.
I've built my career at agencies around the world: TBWA\Chiat\Day in Los Angeles, Crispin Porter + Bogusky in Colorado, Happiness in Brussels, and Dentsu Achtung! in Amsterdam, working across just about every category along the way. Today I lead NEXT, the innovation arm of Chiat\Day, helping brands craft immersive, future-forward experiences that go beyond traditional advertising. Everything I make runs through one question: is technology letting me do something I otherwise couldn't do before?
The work has been recognized at most of the major festivals, including a Red Dot Grand Prix, Eurobest, Epica, ADCN, and Esprix, for campaigns like Adobe "Hovering Art Director" and the "Volkswagen Stroller." But honestly, I'm just as proud when the work breaks into culture. Lately that has meant "Played by Humans" with Jazz Is Dead, a movement and verification tool defending human-made music in the age of AI; the LA Rams "Thursday," our reimagining of the cult film "Friday" for draft night starring the sons of Ice Cube and Chris Tucker; and Instacart's first-ever Super Bowl ad "We're Here," an Avengers-style team-up of America's most iconic grocery mascots. With Jack in the Box I built "DealQuest," an AI-powered game you can actually eat that landed me on AdWeek's AI Power 50 in 2026, brought Mark Hamill back to the drive-thru that once fired him, and made the brand's first horror short, "Feeding Time."
Originally from the Netherlands, ex-competitive gamer, and tall enough to play basketball but, being Dutch, not actually good at it. So probably don't ask me to play basketball.
