Dentsu Thailand is building on a strong business momentum, appointing creative industry veteran, Phannika Vongsayan, as Chief Growth Officer, with effect July 15, 2026, underscoring the network’s confidence in its trajectory to broaden its impact across Thailand.
As Chief Growth Officer, Phannika will be responsible for building new client opportunities, strengthening strategic partnerships and shaping commercial growth initiatives, including a sharpened focus on scaling dentsu Thailand’s creative ambitions to match a market that continues to raise the bar.
The newly created role reflects the network’s continued investment in the expertise and leadership needed to fuel its growth journey, building on the strength of its creative capabilities and years of robust industry standing, with the ambition to grow even further.
Sanjay Bhasin, CEO, dentsu Southeast Asia said, “We have earned our position in Thailand over many years, building through consistency, enforced quietly, over time. Consistency like that has to be protected by continuing to push forward. We are therefore investing in growth because we believe there is more to win. Specifically, the expectations of brand ideas and craft are scaling fast and at a new level of sophistication. We have a team built for exactly that, and what we need now is someone who can make sure that capability reaches every opportunity it deserves to. Phannika joins a business that is already on the front foot. She has built a strong track record of growing businesses in this industry, and brings the rare instinct to grow from a position of strength. I am confident she will bring that same rigour to dentsu Thailand.”
Phannika brings more than two decades of experience building and scaling agency businesses in Thailand. She co-founded Wolf BKK from the ground up, establishing it as one of the country’s most recognized creative agencies, before taking on a leadership mandate to reset and rebuild TBWA\ Group Thailand as Group CEO. Beyond agency leadership, she is an active contributor within the creative industry, having served as a juror for the ONE Asia Creative Awards, the Gerety Awards, and multiple editions of the APAC Effie Awards. Her jury appointments reflect expertise across creativity, strategy, effectiveness, and business growth.
Phannika Vongsayan, Chief Growth Officer, dentsu Thailand, said “Thailand is a market with deep creative talent, entrepreneurial energy and increasingly complex business challenges, making it an exciting place to drive the next chapter of growth. dentsu has built a strong position through the strength of its people, integrated capabilities and long-term client partnerships. As the advertising industry evolves, we have an opportunity to redefine the role of agencies by moving beyond delivering campaigns to becoming more meaningful growth partners for clients. By bringing together the full breadth of capabilities across the dentsu network, we can create greater value and play a more strategic role in our clients’ business growth. I am excited to join the team and help unlock even greater ambition together.”
The appointment marks another step in dentsu Thailand’s continued investment in building a business equipped for its next era of growth. With a strengthened leadership bench and a clear ambition to broaden its impact, the network remains focused on creating long-term value, expanding its market presence and continuing the momentum it has built over many years.
