Bellass, who spent eight years at Mother and is a former board planning director at TBWA and GGT, has taken a director role at the London agency.
He has a brief to expand Splendid’s offering into a broader range of comms.
He said he had left the advertising world for a PR agency in order to create ‘communications ideas that engage people on a physical level and are able to reach beyond the confines of paid-for media’.
He cited ‘new forms of digital software’ and revamping shops’ layouts – with PR used to ‘amplify’ those ideas – as examples of what he hoped to work on at Splendid.
At Splendid – which was founded in 2003 – he will be running the business alongside MD and founder Alec Samways and PR director Kathryn Pringle.
Samways said the fact Bellass has ‘left a top job with one of the world’s best creative agencies to further his career beyond advertising’ was ‘both a huge compliment to Splendid and a sign of the changing nature of the marketing industry’.
Clients for which Bellass worked at Mother include Coca-Cola, SAB Miller, Orange, Amnesty, Super Noodles and Pot Noodle.
Bellass said: ‘Working for Mother has been an incredible experience. I shall miss it dearly.’
Splendid clients include Marmite, Peperami, the Lawn Tennis Association and Smirnoff.
