Portrait of Carl Jannerfeldt

Creative director and founder of Rocket—Science, an independent creative studio in Stockholm.

Before that I was executive creative director at Prime Weber Shandwick, responsible for the agency’s creative output, its talent and its new business. In two years it went from 30th in the country to Sweden’s most awarded agency, Guldägget 2023.

At R/GA New York I ran cross-disciplinary projects for Verizon, Samsung, LEGO and Uber, and led new-business pitches that covered strategic positioning, branding and campaigns.

As an independent creative director I made work for Samsung, T-Mobile, Verizon, Chobani, Pepsi, The North Face, Dove, Timberland, Disney and General Mills.

I started as a copywriter: Farfar in Stockholm, then BBDO and Wieden+Kennedy in New York, on Nokia, AT&T, Delta, Heineken and Southern Comfort. I’ve worked on almost every kind of product, from self-driving cars to robotic lawnmowers, alcoholic drinks and refugee shelters, and the aim has been the same every time: work people can’t ignore.

Born in Sweden, raised on both sides of the Atlantic, based in Stockholm.
