Dentsu Aegis-owned agency Vizeum has appointed its first mobile director for Asia Pacific, as it responds to the rapid growth of smartphone ownership in the region.

Wohlstand Cheah joins from Millennial Media, where he was regional mobile advertising sales director for Malaysia and Thailand.

He will be responsible for building Vizeum’s mobile capabilities across the region, working with clients to “develop mobile solutions that drive business value”.

Singapore-based Cheah will report to Vizeum Asia Pacific managing director Duncan Pointer, himself appointed to the role last month.

Pointer said: “[Cheah’s] appointment will accelerate Vizeum’s focus on mobile. Having this specialist skillset fully integrated into our strategic planning teams will help clients leverage the spectrum of opportunities mobile marketing offers.”

Cheah added: “Vizeum’s ambition and its vision for mobile is what sets it apart from its competitors. I’m excited to join the team and to work across the region delivering mobile first solutions for our clients, and for Vizeum.”

Prior to joining Millennial Media, Cheah was Asia Pacific regional sales manager at Nokia.
