James Fox, former CEO of Havas London, Imali Hettiarachchi, former strategy lead at The Lego Group; and Augusto Sola, former creative partner at Lucky Generals New York, have launched Juju Studio, an agency billed as a “creative residency for brands” that’s “rooted in Latin American values.”
Juju Studio is backed by Untold, a network of more than 600 people that originated in South America and extended to Miami before this UK launch, its first in Europe. Fox, Hettiarachchi and Sola join the ranks of creative shops that are using the expertise of senior executives as its selling point.
Fox left Havas in January 2025 and was replaced by MD Holly Ripper. Hettiarachchi spent five years at Lego and previously worked at BBH, addam&eveDDB and Pablo. Before joining Lucky Generals, Sola was a founding partner at 101 London and moved on to Mullen Lowe after the acquisition.

Fox said: “The best results I’ve seen have always come from the best relationships: senior, frank and outcome-led. Too often the model gets in the way of that. Juju Studio is built so it doesn’t. Our residents get the three of us, and we’ll be judged on what we achieve together, not on the hours we log.”
Hettiarachchi said: “Being inside one of the world’s most successful brands has changed how I see strategy work. I saw how much a brand’s value is shaped long before anyone writes a comms brief. Some of the strongest strategic thinking happens in that early space, when the business problem leads the way, not deliverables on a brief. That’s the spirit we’ve built Juju Studio around.”
