The compounding effect of minor product optimizations.

When I started implementing paid subscriptions for RocketSim, it took me 13 months to get from $0 to $1000 Monthly Recurring Revenue. 

A few years later, I’ve been able to grow from $4000 to $5000 in just 3 months

There’s no single reason for this growth improvement: it’s many minor improvements combined.

Obviously, RocketSim has become more mature, more developers are using it, and due to low churn, I’m building up a larger subscription base. Yet, I’m certain many of the small improvements in retention, onboarding, and ‘ah-ha’ moment conversion lead to this improved growth.

The key takeaway should be to not only focus on delivering new features but to keep an eye on core metrics and try to improve these regularly. Better retention leads to more customers and more upsell opportunities.

I bet your app uses many third-party libraries, but did you also respect their licenses? Or do you even know how to respect their licenses? While many libraries are free to use, there's a legal requirement to acknowledge usage in your app.
