The Challenge
The problem nobody wanted to have
Coca-Cola needed a holiday campaign that could scale to millions of simultaneous users, with strict brand identity, real people's images, and zero margin for error during the year's most critical dates.
1
Unpredictable scale
How many people will message during the holiday season? There's no way to know — and it can't fail.
2
Reputational risk
Real people's images with a global brand. Moderation can't depend on humans.
3
Creativity at scale
Real personalization without losing Coca-Cola's visual language across any asset.
4
Critical window
The campaign runs for 30 days. Every hour of downtime is lost visibility — and it doesn't come back.
The Solution
Generative AI as the campaign's operating system
biia industrialized GenAI in production: a complete conversational flow on WhatsApp, no apps, no friction, across 8 countries at once.
