Dare will work with EE on developing and maintaining its digital properties, including its website and mobile interfaces. It is thought the brief could be extended to include social media.
The appointment follows a formal pitch process that began in January. It does not affect EE’s existing agency relationships with creative agency Saatchi & Saatchi, digital agency Poke or media agency MEC.
It is understood that the win represents a significant amount of business for the agency, which worked with EE rival Vodafone until late last year when Rainey Kelly Campbell Roalfe/Y&R added the digital business to its ad account.
An EE spokesman said: "We can confirm that EE have recently started working with Dare, who have been appointed to deliver a number of significant creative and innovative online programmes for us, to help evolve our digital brand and capabilities."
