On the podcast: the experiments behind Mojo's 60% lift in ARPU, why a winning paywall in Japan completely failed in the US, and why not relying on day one for most of your revenue is actually a strength.

This conversation is shorter than usual and will be featured in RevenueCat’s State of Subscription Apps report. Each episode in this series will explore one crucial topic and share actionable insights from top subscription app operators.

Top Takeaways:

🌍 A winning paywall in one region can completely fail in another
A long scrolling paywall with detailed comparisons drove a 20% revenue lift in Japan but failed in the US, where cleaner designs with punchy messages performed better. Always retest regional winners before global rollout.

💪 Getting only 50% of revenue on day one is actually a strength, not a weakness
While most apps see 80% of revenue on day one, getting half from existing users signals strong retention, generous free tier value, and healthy long-term monetization beyond onboarding.

⚡ Experiment velocity is a huge unlock for paywall optimization
Using third-party platforms to shorten iteration cycles from days to hours, running parallel test streams across geo segments, and taking more shots overall creates shorter feedback loops and compounds learning over time.
