How Sprite & Gan.AI Created Award-Winning Personalised Digital Ads

Sprite’s existing campaign featuring Vedang Raina (and aligned with brand’s “chill”, “take a break” positioning) resonated with teens and young adults. But the brand wanted to go deeper in digital. They wanted to deliver messaging at the moment of relevance, aligned with what the viewer was doing and when they were doing it.

Key challenges included:

• Translating a TV narrative into a digital format that felt personal, not generic.
• Creating a large-scale personalised ad experience (across many viewer contexts) while maintaining brand consistency.
• Delivering relevance not just by name, but by activity, time of day and viewer mindset.

Working with Gan.AI’s Studio platform, the team developed a dynamic and personalised AI videos with three major pillars:

1. Hyper-realistic digital avatar of Vedang Raina – Sprite recorded footage (~10 mins) that Gan.AI used to create an avatar with voice-clone and lip-sync. Thus, enabling consistent, personalised delivery.
2. Long-form, meaningful personalization – Rather than simply inserting a viewer’s name, the ads used full sentences that referenced the viewer’s activity and the time of day.
   Example: “It’s 10 o’clock, time to start your gaming session. Chill with Sprite.”
3. Activity- and time-based targeting logic – Based on YouTube search behaviour, the ads identified nine viewer activity categories (Gaming, Social, Music, Movie, Food, Travel, Tech, Comedy, TV) and dynamically served the correct variant for the moment.

Together, these pillars transformed a simple campaign into a deeply contextual, highly personalised digital experience. All delivered at scale. By combining creative storytelling with cutting-edge AI, Sprite didn’t just reach its audience. It spoke to them in the exact moment they needed a break.

And that powerful blend of relevance + innovation is what ultimately helped the campaign stand out and earn industry recognition.

Gan.AI’s Campaign Execution

Executing this level of personalisation demanded a precise blend of AI-driven automation and brand-safe creative control. Here’s what we did:

• Over 200 distinct video variants were generated, each tailored to a combination of viewer activity + time of day.
• Served as pre-roll ads on YouTube, enabling high relevance at the moment the viewer was already engaged in content.
• Avatar footage allowed Sprite to maintain brand tone, personality and visual identity while dynamically adapting the message.
• The creative integration ensured that the TV narrative fed into this digital experience. Thus, giving a seamless brand story across channels.

Powered by Gan.AI, Sprite transformed its TV campaign into a scalable, personalised storytelling engine that delivered measurable relevance and industry-level acclaim.

Results & Impact

The results were unmistakable — stronger engagement, a more immersive brand story, and recognition from leading industry awards. Here are the key highlights,

• Hyper-Personalised Engagement: The campaign delivered deeply relevant ad experiences by aligning message to viewer behaviour and time.
• Expanded Brand Narrative: The brand’s TV storyline was extended and enriched via personalised video variations, increasing immersion and brand connection.
• Award Recognition: The campaign’s innovative use of personalised video advertising and AI-driven avatar tech helped the work stand out in industry award forums.
  According to the winners list for the Campaign India Digital Crest Awards 2025 (CIDCA), Sprite’s “End of Day Chill” campaign is recognised under the category Media Impact & Marketing Excellence – Best Conversational Marketing/Media Innovation.

Ultimately, Sprite proved that when human creativity meets AI-driven personalisation, campaigns don’t just perform. They set new standards.

Here’s what this means for brands,

• Scalability meets personalisation: With AI-driven tools like Gan.AI’s avatar and video engine, creating hundreds of unique AI video ad generation becomes feasible, and meaningful.
• Timing + context = relevance: Serving the right message at the right time (and referencing what the viewer is doing right then) dramatically increases viewer resonance.
• Brand consistency maintained: Using a single recorded avatar rather than multiple actors/cuts ensures consistency of look, feel, tone across all personalised variants.
• Award-grade innovation can drive business results: Creative + tech + context = standout campaigns that both deliver and get recognised.

Key Learnings & Best Practices

Sprite’s campaign highlighted a set of clear principles that make personalised video truly resonate. From context-rich messaging to avatar consistency and smart production workflows. These learnings can serve as a blueprint for any brand exploring AI-powered creativity.

Here are the key takeaways.

• While name personalization is common, personalising full sentences to viewer context drives a deeper emotional connection.
• Segmenting by activity + time of day unlocks relevance that generic targeting cannot.
• Use a single avatar asset to maintain brand tone, while dynamically altering message components.
• Prepare for production by capturing high-quality reference footage up front, so the avatar retains natural expression and lip sync.
• Align the personalised experience with your existing brand narrative (TV or other channels) to leverage continuity and reinforce brand story.

Taken together, these learnings show that personalisation works best when it’s purposeful, consistent, and deeply tied to the brand story.

Looking Ahead

Sprite’s success with this campaign paves the way for future innovation: more segments, more viewer contexts, perhaps branching into interactive or full-scene personalization. For brands who want to move beyond one-size-fits-all digital ads, this case exemplifies how creative ambition plus tech capability deliver results, and recognition.
