Improving Return on Ad Spend (ROAS) is a top priority for every direct-to-consumer (DTC) brand. In this detailed case study, you'll discover exactly how one DTC company leveraged AI-generated ad creatives to achieve a remarkable +42% increase in ROAS—all while significantly streamlining their creative process.
Background: The Challenge
A growing DTC e-commerce brand was facing common issues:
- High ad creative costs: Frequent hiring of freelance designers inflated marketing expenses.
- Slow creative turnaround: Manually producing and testing ads was slow, reducing agility.

They input simple prompts related to their product offerings. Within seconds, Ad-Studio AI delivered multiple high-quality ad visuals optimized for performance.
Step 2: Instant A/B Testing
The marketing team instantly launched A/B tests using multiple AI-generated variants, rapidly identifying which ads drove the highest conversion rates and best cost-per-acquisition (CPA).
Step 3: Continuous Optimization
Each week, the brand iteratively tested and scaled their best-performing ad variants, ensuring continual improvement and optimizing their marketing spend.
