The social media giant has hired Helen Prowse from Diffusion PR, to take on the new role of UK comms manager.
Prowse, who featured in the PRWeek 29 under 29 in 2010, joins Twitter on 23 July. She will report to European comms manager Rachel Bremer, allowing her to widen her focus across Europe.
Prowse told PRWeek: ‘In only six years, Twitter has had a profound effect on the communications landscape.
‘For me, this role is one of the most exciting opportunities the industry has to offer and I’m hugely excited about joining the team.’
She has been brought in to illustrate how Twitter can connect UK consumers with the people and brands they are passionate about. She will also promote the brand's tie-ins with sport and music events.
The appointment comes as Twitter's search for its first UK PR agency draws to a close.
