The Academy merged with Shine Communications in January, to create the new business led by CEO Mitchell Kaye and creative director Dan Glover, both formerly of The Academy.
Kaye and Glover will lead the Domino's account and report to Nina Arnott, head of comms at Domino's.
Shine @ The Academy will manage day-to-day, proactive and reactive media relations and social media.
Arnott said: "Domino’s is now the UK’s biggest pizza company and PR is seen by our CEO and leadership team as a critical tool for promoting and protecting our brand as our profile grows. We loved the team's passion and energy, and felt their ambition matched ours."
Following a competitive repitch in the Republic of Ireland, Domino’s has reappointed Harris PR for brand and community consumer campaigns.
