How We Scaled a Conversation Card Business to 2.5x Purchase Growth in 3 Months While Cutting CAC by 20%

Jul 21, 2025

About the Business

This DTC e-commerce brand sells card-based conversation starters designed to spark deeper connections—whether on first dates, at family dinners, or during relationship check-ins. The product bridges entertainment and emotional intimacy, offering a structured way to foster meaningful dialogue in an increasingly digital world.

The Challenge

After achieving strong initial growth through Facebook ads, the brand hit a classic scaling wall:

  • Customer Acquisition Costs (CAC) were rising, squeezing margins

  • Top-of-funnel growth felt unpredictable and expensive

  • Scaling ad spend didn’t reliably lead to proportional growth in purchases

The mission was clear: scale Facebook ads while maintaining—or reducing—CAC.

My Approach

I started by auditing the ad account with a sharp focus on segmentation. This wasn’t just about demographics—it was about buying intent, emotional context, and relationship dynamics. The goal was to identify distinct customer avatars based on:

  • Age, gender, and relationship status

  • Use cases (e.g., dating, family game night, couple therapy support)

  • Behavioral data and messaging resonance

Once the audiences were redefined, I realigned ad messaging and creative around the emotional value of the product—not just the utility.

The Results (Month by Month)

Month 1

Identified and isolated high-intent customer avatars. Adjusted creative and campaign structure to reflect different emotional use cases.

Month 2

Early signs of efficiency: CAC dropped by 5%. Purchases stabilized even as we began scaling budgets modestly.

Month 3

Scaled up purchases by 70%. Introduced new creative variants, layered in UGC, and focused heavily on retargeting warm audiences. CAC dropped by 20%.

Month 4

With systems in place and performance steady, we scaled to achieve a 2.5x increase in total purchases compared to March—while maintaining the reduced CAC baseline.

Conclusion

This project proved something I’ve seen time and again: growth isn’t just about spending more—it’s about knowing who you’re talking to and why they buy.

By digging deep into customer psychology, fine-tuning creative to match emotional drivers, and scaling intentionally, I helped this conversation card brand unlock the next phase of its growth—profitably.

If your e-commerce brand has hit a performance plateau or struggles with rising CAC as you scale, know this: the solution isn’t always a bigger budget. Sometimes, it’s a sharper lens.
