Isobar head Barney Loehnis to depart

Isobar, the digital arm of Carat, has not selected his replacement, Loehnis said.

He adds that he has not decided on his next move but he is exploring his options and will look to remain in Hong Kong.

Loehnis joined the agency in 2006 from Warner Bros' online division, where he was European director.

At Isobar, Loehnis drives business development and client management, working with other network directors in London, Stockholm and San Francisco.

At the time of his hire, Isobar said Loehnis' appointment was part of a strategy to develop a dedicated resource that can reflect its philosophy and effectively service global clients.

“I decided that, after four years, I wanted to find a new challenge,” Loehnis said of his departure, noting that, during his time at Isobar, the agency has doubled in size and had won key client accounts, including Procter & Gamble. “The next phase of Isobar looks like it will last another four years, and I think I want to find a new perspective and this is a job for the next director.”

Loehnis oversees the digital services of clients across Asia-Pacific, covering 14 countries and 500 people.

Isobar’s recent developments under Loehnis include facilitating the launch of CRM platform Astro for wwwins Consulting; establishing a production hub in China; and unveiling its search engine marketing platform iProspect in Singapore, New Zealand and China, the latter through a partnership with Baidu.
