Ballantine left Revolver in November 2005, a year after selling the agency to Leeds-based marcoms agency Propaganda.
For the past 12 months he has been freelancing as an experiential marketing and intellectual property consultant.
He takes a new role at Launch, seeking to grow the agency's experiential offering and build a dedicated team capable of both supporting current clients and winning new experiential-based business.
Ballantine said clients were becoming ‘more savvy about ways to engage with consumers'. He wants to get Launch involved in ‘braver' experiential projects.
‘Launch can now offer the three marketing disciplines best placed to take advantage of the ongoing fragmentation and segmentation of media: PR, digital and experiential,' he said.
The agency's experiential work for clients such as BP and Pernod Ricard was previously handled by client teams.
It is currently recruiting for a new head of its corporate practice, following the exit of Paul Maguire. (PRWeek, 1 Dec).
