Based in Stockholm and founded in 2000, the 22-strong Farfar will become part of the Aegis digital network Isobar, which launched last year and has bought 10 agencies in the last seven months.
The Cannes Cyber Lion Grand Prix-winning agency winner Farfar, which means "grandfather" in Swedish, includes Red Bull and Milko among its clients. The founders, including CEO Matias Palm Jensen, previously founded Spiff Industries.
Nigel Morris, worldwide president of Isobar, said: "Farfar is an outstanding agency producing some of the most creative work in the digital world. The Isobar vision of digital marketing and the network we are developing has creative at its heart. We are seeking to push the boundaries as we move into a more immersive, interactive and non-linear world."
The acquisition follows that of De-construct, for which Aegis will pay £4.8m over three years, earlier this week.
According to Matias Palm Jensen: "At Farfar, we create advertising for the internet. We have always set out to communicate with the hearts of the audience and create liking, rather than branding. This doesn't mean we don't believe in the mechanics of a strong brand. We just don't like funny things that serve no purpose... at least not when it comes to advertising."
