Field notes on monetization.
What we're learning about paywalls, pricing, and experimentation — from our own product and thousands of live tests.
Perspective
Your paywall is the most important screen in your app
And it’s probably the one you’ve spent the least time on. Here’s the case for treating it like a product.
Engineering
Sequential testing: stop waiting for fixed sample sizes
Why we moved to always-valid inference, and how it lets you call winners sooner without inflating false positives.
Playbook
The anatomy of a high-converting session-limit paywall
Five patterns that consistently win when a free user hits their limit — with examples.

Engineering
How the agent predicts lift before you ship
A look under the hood at the cohort-prior model that scores every draft the agent writes.
Playbook

We ran the test across dozens of apps. The answer is less obvious than the pricing blogs suggest.
