Holden’s arrival at Karmarama in April coincided with the group stopping the use of the Kaper name to describe its PR services. That was part of a wider strategy of integration across the marcoms group since its acquisition by Accenture in 2016.
Chris McCafferty, managing director at Karmarama - whose PR clients include IKEA and Vauxhall - said: "We can confirm Rosie left the business earlier this month. We wish her well for the future."
He added that Karmarama "remain[s] committed to PR" and is "hiring the right leadership to run that practice".
In August, PRWeek reported that Karmarama chose not to re-pitch for the Virgin Trains Christmas campaign account amid changes in its PR operation, with the impending departure of a number of staff, alongside new arrivals.
Holden spent six years as MD of PR agency John Doe before joining Karmarama, working with clients such as Adidas Originals, Beats by Dre and Pernod-Ricard brands including Absolut and Malibu.
