Hearts & Science Lands WW International in Post-Merger Global Push

Hearts & Science has secured a major new client in WW International, Inc., the parent company of Weight Watchers. This win marks the agency's second high-profile global account since Omnicom's acquisition of IPG in late 2025. The partnership will cover media strategy across nine key markets, with the first campaign already running.

The appointment follows Hearts & Science's recent success in landing the TK Maxx European media account. WW International, Inc. has now chosen the agency to handle both brand and performance media in Western Europe, Australia/New Zealand, and Canada. The UK and German offices will lead the work, overseeing teams in Belgium, France, Sweden, Switzerland, the Netherlands, and North America.

The first campaign under Hearts & Science launched during the 2025 festive season. It has since expanded to align with New Year resolutions in early 2026. Charles Quartey, VP of International Marketing at Weight Watchers, highlighted the agency's speed, agility, and expertise in blending brand and performance strategies.

This win is significant for Hearts & Science, as it represents only the second major global brand added to its roster since the Omnicom-IPG merger. Both TK Maxx and WW International, Inc. are now flagships in the agency's international portfolio.

The partnership solidifies Hearts & Science's position in managing large-scale, cross-market media campaigns. With the UK and Germany at the helm, the agency will coordinate efforts across multiple regions. The ongoing campaign reflects the brand's push to engage audiences during key seasonal moments.
