Casey left Prodigy four months ago in what he described as an ‘amicable parting'.
Casey, who has worked with clients such as AOL, Orange, Nintendo and Sony in a 16-year tech PR career, will report directly to Liberty MD Dee Gibbs.
His challenge is to double business-to-consumer revenue at Liberty in the next 12 months.
‘I started Prodigy from scratch and I have enough contacts under my belt,' he said. ‘I really do know my consumer tech space. ‘Liberty is already respected in B2B media relations for service companies and suppliers. I have known Dee as a friend and colleague for 12 years, and she is very keen to kick-start the business-to-consumer side.'
Casey will also try and squeeze consumer work from Liberty's existing B2B clients.
‘They are planning wider branding campaigns and we are actively talking about business-to-consumer campaigns,' he said.
The company is about to sign two ‘small' business-to-consumer clients. Casey would not reveal their identities, but he added: ‘We are also in talks with a couple of big ones.'
Prodigy replaced Casey with Text 100's New York senior V-P Simon Craddock (PRWeek, 17 March).
