Commenting on the dual appointment, Behnam said the Adz team would benefit from their extensive experiences. "Langton’s leadership experience at various agencies will be invaluable as we continue to bring efficiencies to digital media planning and buying practices across the Asia-Pacific region. Choi’s pedigree and experience across various leadership positions in Korea and Southeast Asia will help us develop deep client relationships in the region," he said.
