Hesling, who was part of the team that launched Burda's first UK title, Full House, is believed to have left the company without a job to go to.
Since its launch last March, Full House has failed to make an impact on newsstands. The weekly magazine, which is aimed at a C1C2D audience, has been delisted by certain retailers and is now thought to be selling around 120,000 copies a week. Its rival publications, H Bauer's Take a Break and IPC Media's Chat, sold 1,200,397 and 609,163 copies respectively, according to August's Audit Bureau of Circulations figures.
Before being made Burda's managing director, Hesling acted as a consultant while the publisher established its UK operation. Before that, he was the head of international development at Attic Futura.
News of Hesling's departure comes a week after Burda's UK arm launched its first monthly magazine, Living & Gardens (Campaign, 25 November).
The title, edited by the former Real editor Sian Rees, is aimed at thirtysomething women and costs £3.20.
The publisher is also planning a second monthly title later this year, but details are under wraps.
Hesling could not be contacted and nobody at Burda was available for comment as Campaign went to press.
