Cohort math and learning from subscriptions

On the podcast, I talk with Greg about knowing when to pivot, why most consumer apps shouldn't raise VC, and why making free trials optional outperformed making them the default.

Top Takeaways:

📉 Know When to Pivot
 Wrangle struggled because it wasn’t solving a real problem. Burner succeeded because it met a clear need. Don’t be afraid to pivot when the product isn’t working.

💭Most Consumer Apps Don’t Need VC

Venture capital can be a blessing but also a curse. If you attract investment that doesn’t line up with your product vision or culture, the cash injection can turn out to be a costly mistake. Building a business that pays for itself is a better fit for most founders.  

🔑 Focus on Retention
 Success is about keeping users, not just acquiring them. Burner’s ability to retain users, even short-term ones, proved its value. If users keep coming back, you’ve found something meaningful.

🛠 Trials, Errors, Wins
Testing was crucial to Burner’s growth. Every experiment was a learning opportunity. Don’t guess—test continuously, especially pricing, to find what drives retention and revenue.

🎯 Small Changes, Big Results
 Minor tweaks, like switching to a free trial, led to significant growth. Optimize for retention with quick, simple changes. Even minor adjustments can have a substantial impact on results.
