IPG Mediabrands has confirmed the departure of Travis Johnson, global CEO of its mobile arm, Ansible.
“We can confirm that he’s no longer actively involved in the leadership of Ansible as we work through a transition period,” the company said.
As well as global president of Ansible, Johnson was head of mobile for IPG Mediabrands, the umbrella group for Interpublic media agencies including UM and Initiative.
His core responsibilities included leveraging IPG Mediabrands’ proprietary technologies and patents, mobile campaign management platforms, content management systems and social integration technologies.
Johnson had previously been chief executive of IPG Mediabrands Australia, following IPG's acquisition of Australian mobile specialist agency Mnet in 2013. Mnet was rebranded to Ansible in 2016.
Johnson was promoted to global head by fellow Australian Henry Tajer, who stepped down as global CEO of IPG Mediabrands in May, a mere two years after moving his family from Australia to New York.
Tajer, meanwhile, was not replaced as chief executive, with IPG Mediabrands chairman Philippe Krakowsky taking over Tajer's direct reports.
