Day and Seftel joined Wieden & Kennedy this week as creative directors. They report to the executive creative directors, Tony Davidson and Kim Papworth, working on Arla Foods and Three.
The pair began working together at Fallon, creating campaigns for brands including Orange, Sony and Skoda. They moved to WCRS in 2008 and to Mother in 2011. At Mother, they most recently worked on the Moneysupermarket.com account.
Day and Seftel told Campaign that they were keen for a new challenge and more senior roles.
They said: "We look at ads from time to time and, often, the better ones seem to be made by Wieden & Kennedy. We’re very pleased to be here."
