As part of the brief, Threepipe will launch a series of integrated campaigns throughout 2017 to help reposition the Harvester brand and set it apart from restaurant brands such as Nando's and TGI Friday's, said the agency's co-founder Jim Hawker.
The brief had previously been held by Brazen.
Threepipe will also work alongside Harvester's existing digital and social agency Connecting Element to "grow awareness and expand consideration amongst new and existing diners as they look for different dining options," Hawker added.
Anneli Fereday, marketing manager at Mitchells & Butlers, which owns and operates the Harvester brand, said: "Threepipe’s creative ideas really showed us how they can combine PR and social to drive key messages and impact."
