Iris's operating profit grew to £6.2m, and turnover was £90.7m, compared to £93m in 2014.
In early 2015, Iris was appointed as the lead creative agency for Wickes and won accounts with PZ Cussons, Purdey’s, Virgin Active, Maplin and BMW. It expanded existing relationships with Samsung, Britvic, Value Retail and Domino’s.
Iris also opened an office in Seoul, South Korea, and acquired a majority stake in creative agency Founded, which launched in 2012.
Dan Saxby, CEO of Iris UK, told Event: "2015 was Iris’ best year to date. A combination of factors were behind our growth – maturing overseas offices; the international expansion of high margin businesses such as Iris Concise, our CRM, data and consulting business; and the payback from significant investments in content, B2B and sports marketing. 2015 was our first full year of working with Samsung, expanding our relationship with them to new markets and disciplines – including the European PR remit."
