White, who joins from online user experience consultancy Webcredible, takes on the role of senior account manager for the newly established division.
Pete Hendrick, Rocket managing director, commented: 'We've seen a definite shift in business confidence over the past few months, particularly among companies with a digital focus. Jon's recent Webcredible experience is very well aligned to maximising this opportunity. It's great to get him on board.'
