Burson has announced two senior appointments to its global Influence and Social leadership team.
Yuliani Setiadi has been named Burson’s APAC Head of Influence and Social, based in Singapore, while Davitha Tiller will join the agency as U.S. Chair, Influence and Social, later this month.
Alongside Olly Gosling, Head of Influence and Social, EMEA, they form the agency’s regional leadership team reporting to Matt Buchanan, Global Chief Influence and Social Officer.
Vikki Chowney continues as Global Head of Influence and Social and the capability’s global strategy lead, working closely with Buchanan to advance the agency’s approach worldwide.
“Reputation is no longer built through a single channel, format or voice, but through ideas that originate in culture and society, travel through communities and stakeholders, and earn attention across every platform,” said Buchanan. “With Yuli and Dav joining Olly and Vikki, we now have the leadership in place across our regions to bring that vision to life for clients at scale.”
Yuliani Setiadi, APAC Head of Influence and Social, brings more than 20 years of experience building and scaling influence, social and digital capabilities across Asia-Pacific.
Most recently, Setiadi was Head of Digital for Southeast Asia at Edelman, having previously led the agency’s digital practice across Hong Kong, Taiwan and Thailand.
In her new role, Setiadi will establish the APAC Influence and Social Centre of Excellence and lead the regional execution of Burson’s global strategy, integrating the agency’s innovation and intelligence tools to build next-generation client solutions. She officially started on November 4.
“Influence and social are fundamental to how reputation is built today,” said HS Chung, CEO, Burson Asia-Pacific. “Brands in this region are navigating digitally native audiences, fast-evolving platforms and diverse cultural and sub-cultural contexts, all at once. Yuli brings deep regional knowledge and decades of experience building influence capabilities and delivering social-first strategies that drive brand love and business impact. Her expertise will build on our existing strengths, offering clients more powerful ways to connect with their audiences.”
Davitha Tiller, U.S. Chair, Influence and Social, will lead Burson’s Influence and Social offering in the U.S., helping clients navigate the expanding ecosystem of voices that shape reputation. She brings more than 15 years of experience building, scaling and transforming social and influencer capabilities.
Tiller will join Burson from Havas on November 30.
She spent the past decade in senior social, influencer and integrated communications leadership roles spanning APAC, the U.S. and global markets.
“Wherever reputations are being shaped, influence is at work,” said Craig Buchholz, U.S. CEO, Burson. “From creators, cultural icons and experts to media, analysts and thought leaders, influence is increasingly at the center of how our clients are engaging with the world. Davitha brings a deep understanding of how influence and reputation intersect, and how to harness that relationship to drive meaningful impact for our clients.”
