The challenge
Sunnyside, a mindful drinking app, was struggling with rising paid media costs. While their team had many creative ideas, they lacked a fast, low-risk way to understand which ads would actually drive conversions, especially across their diverse audience segments.
Solution journey
After identifying the need for more predictive creative insights, Sunnyside partnered with Gins AI for its ability to simulate audience responses at the persona level before campaign launch.
Implementation process:
Defined their key customer personas
Upload multiple creative concepts for Instagram
Used Gins AI to simulate responses from 20 people matching Sunnyside's key customer personas
Instantly evaluated everything from emotional resonance to conversion likelihood
Identified winning creative approaches before spending real media dollars

Results & impact
The pre-launch testing revealed clear patterns in what resonated with Sunnyside's target audiences. The most significant finding was that authentic content consistently outperformed more polished, produced content across all audience segments.
Key performance outcomes:
Reduced CAC by cutting low-performing ads before spending real dollars
Identified winning creative approaches across four unique personas
Established Gins AI as their "creative co-pilot" for ongoing campaign development
Key insights & learnings
Through their work with Gins AI, Sunnyside discovered five principles that now guide their creative development:
Real people outperform polished design: Across every audience, ads that showed authentic stories, supportive messaging, and achievable next steps drove the highest conversion intent.
Visual storytelling accelerates understanding: Simple illustrations (like balance/contrast) communicate mindful drinking faster than words alone.
Supportive tone builds trust: Non-judgmental messaging ("We're here for you") resonated strongly with all segments.
Flexibility resonates across audiences: Framing alcohol change as flexible ("soberish", "mindful") resonated most across all audience types.
Clear next steps increase action: Specific timeframes (like "28 days") and clear CTAs reduce friction and increase conversion intent.
Implementation impact
By implementing these insights, Sunnyside transformed their approach to creative development. Rather than launching campaigns based on intuition, they now use data-driven insights to guide creative decisions before allocating media spend.
"Gins AI has become our creative co-pilot, helping us get insights that reduce CAC by cutting low-performing ads before spending real dollars," notes Ian, CGO at Sunnyside.
Additional use cases
Sunnyside continues to use Gins AI as an integral part of their creative development process. The platform allows them to:
Validate messaging and positioning before campaign launch
Create landing page content that's ready to deploy
Social media strategy and organic content development
New product offering concept testing
