Speculation suggests Jackaman will be joined by two former employees – WS Square Mile director Melissa Rowling and account director Ian Pope.
WS Square Mile MD Ian Bailey confirmed Rowling and Pope would leave within the next month, but would not say whether they are joining the new venture.
Jackaman left Weber Shandwick in 2004 after completing his earnout arrangement inherited by WS from its merger with BSMG Worldwide in 2001 (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.
WS Square Mile has not yet directly replaced Rowling and Pope but will be making appointments ‘over the next month’.
WS Square Mile stalwart Kevin Smith left after 14 years for Citigate Dewe Rogerson earlier this year.
Bailey took overall charge of WS Square Mile as managing director last year.
