The agency has been tasked with placing the brand at the heart of the debate surrounding Generation Rent, which campaigns for affordable private rented homes.
Diffusion will be positioning WeRoom as an alternative for consumers, letting agencies and landlords. It provides people with the ability to find their perfect flatmate, by enabling them to browse through profiles, define personal requirements, compare the best offers and find a room to fit their lifestyle.
Tom Malcolm, director at Diffusion, said: "As more of us rent for longer, the importance of a healthy, happy and affordable flatsharing experience has never been greater. WeRoom has a fantastic mission to help bring like-minded people together in great properties and help consumers to better make the connections that matter."
Thomas Villeneuve, chief executive of WeRoom, said: "WeRoom has a real opportunity to shake up the UK flatsharing industry and Diffusion has developed a creative and integrated campaign to help us to do just that."
