From chocolates to toothpaste: Wavemaker’s Chintan Thakker switches lanes
MUMBAI: Chintan Thakker has traded sweet treats for dental care. The senior business director at Wavemaker India, who spent the past four years crafting campaigns for Mondelez’s snacking empire, is now leading the agency’s integrated marketing communications for Colgate.
The move caps a 14-year career that began in social media analysis and meandered through entrepreneurship before landing Thakker in his current role. His time with Mondelez proved particularly fruitful: the campaigns he orchestrated earned India its first Cannes Titanium Lion and racked up over 300 national and international awards in just two and a half years.
Thakker joined Wavemaker in May 2021 as director of innovation and integrated marketing communications, building a seven-person team and driving technology and content partnerships for Mondelez India. He was promoted to senior business director this month./
His earlier ventures were less gilded. In 2015, Thakker co-founded twentythree, a boutique digital agency that worked with Discovery Channel, Animal Planet and TLC. He also launched Odd Giraffe Lifestyle, a women’s brand that folded after seven months in 2017—a failure he credits with sharpening his strategic instincts.
Before striking out on his own, Thakker climbed the ranks at digital agencies Gozoop and EveryMedia Tech, managing social media for brands including Hyundai, PepsiCo and Bollywood studios. He started his career in 2011 as a video editor and reporter at Fuzion Productions.
The Colgate account marks fresh territory for Thakker, who has spent recent years immersed in the language of indulgence. Now he must master the vocabulary of oral hygiene.

New structure aims to sharpen execution, accelerate transformation and drive client growth
Tokyo: Dentsu Group has unveiled a sweeping global management shake-up, appointing Takeshi Sano as president & global ceo, effective March 27, 2026. The move is aimed at supercharging execution, driving client growth and accelerating the group’s transformation across 120 countries.
Sano, who currently serves as ceo, dentsu Japan and deputy global coo, has transformed Dentsu Inc. into an integrated growth partner, delivering 11 straight quarters of revenue growth and strong profits for two consecutive years.

Regional CEOs and practice presidents will now report directly to Sano, enabling faster decisions and tighter client alignment. A new global chief transformation officer and global chief corporate affairs officer have been appointed to accelerate enterprise initiatives and reinforce governance.

Shigeki Endo remains global cfo, bringing over 30 years of global finance expertise to the fore. Both, along with Sano, are slated for approval as directors at the March 27 shareholders’ meeting.
Other key appointments include: Beth Ann Kaminkow as ceo, dentsu Americas & chief global client officer; Andre Andrade, ceo, dentsu EMEA; Yuichi Toyoda, ceo, dentsu APAC; Will Swayne, global practice president – media & integrated solution; Pete Stein, global practice president – CXM; Yasuharu Sasaki, global chief creative officer; Miho Tanimoto, global chief HR officer; Noritaka Omi, global chief transformation officer; Jean Lin, global chief brand officer; Yoshiki Ishihara, global new ventures officer; Manus Wheeler, chief of staff; Jeremy Miller, global chief communications officer; Shirli Zelcer, chief data & technology officer.
Additionally, Toby Benjamin has been appointed as chief media officer at dentsu UK.
The shake-up comes as dentsu looks to accelerate its transformation, strengthen governance, and deliver measurable growth for clients worldwide. “By eliminating redundant layers and empowering leaders closest to clients, we can act faster, execute better and generate sustainable value,” Sano added.
Hiroshi Igarashi, Arinobu Soga and Giulio Malegori will step down from the global management team and take on advisory roles, marking a clean slate for the new executive leadership.
With a sharpened management engine, Dentsu is betting on speed, unity and client-centric execution to drive its next chapter of global growth.
