Jackaman left WS Square Mile two years ago and last month confirmed that he would be returning to agency life (PRWeek, 26 May).
GJR already has 13 staff, with nine PR consultants and four on a design team.
Nick Glanvill, formerly CEO of creative comms firm Pauffley, is agency MD.
WS Square Mile director Melissa Rowling and account director Ian Pope have also joined, as tipped in PRWeek (26 May).
‘I’m not trying to emulate Weber Shandwick,’ Jackaman said. ‘They have got thousands of staff and I’ve got nine [PR consultants].’
Jackaman is also joined by Deutsche Bank press officer Anna Watson. Deutsche Bank would not confirm if a replacement had been hired.
Jackaman said the agency was independent and would remain UK-focused, at least initially. It will launch its website, to be developed by its own designers, ‘soon’.
He left Weber Shandwick in 2004 after completing an earnout arrangement inherited by WS from its 2001 merger with BSMG Worldwide (PRWeek, 17 April 2004).
Jackaman had continued to work at WS Square Mile as a freelancer, but has spent the past two years studying for an MA in medieval and Tudor history at Kent University.
