ASL Bloom

Overview:

ASL Bloom is a top-rated language-learning app that helps users master American Sign Language (ASL) through interactive lessons. While the app was gaining traction, rising acquisition costs posed challenges to sustainable growth.
Rocketship HQ partnered with ASL Bloom to optimize acquisition costs and drive scalable revenue growth. Over the course of 12 months, we helped the app reduce cost per paying user by 75% and nearly double its active user base—all while maintaining profitability.

The Challenge:

Despite strong demand, ASL Bloom faced key obstacles in scaling efficiently:

1. 🚨 High Cost per Paying User – Acquisition costs were limiting profitability.
2. 🚨 Scaling Profitably – Growth was constrained by rising costs and inefficient spend allocation.

The goal was to reduce acquisition costs and scale user growth while improving profitability.

Rocketship HQ’s Approach

We deployed a data-driven strategy designed to improve efficiency at every stage of the user acquisition funnel:

• 🎯 Creative Optimization – Testing different ad creatives and messaging to enhance engagement and drive more cost-effective trial sign-ups.
• 🎯 Performance Marketing Scaling – Adjusting bids and budgets to focus on high-intent audiences and maximize efficiency.
• 🎯 Cost Reduction Strategies – Leveraging data-driven insights to optimize channel mix and reduce acquisition costs without sacrificing scale.

By fine-tuning these areas, we were able to drive more high-quality users at significantly lower acquisition costs, improving overall profitability.

Results: Lower Costs & 92% Growth in Active Users

• 🚀 Cost per Paying User decreased by 75% making acquisition far more efficient.
• 🚀 Cost per Trial dropped by 70%, improving conversion efficiency.
• 🚀 Active user base increased by 92% in one year.

With these improvements, ASL Bloom successfully scaled while maintaining strong profitability, proving that strategic acquisition can drive both growth and efficiency.

Conclusion

By leveraging creative testing, funnel optimization, and data-driven scaling, Rocketship HQ helped ASL Bloom reduce costs, boost ROAS, and nearly double its active user base.
