Progressive squeeze freemium conversion
Start with subtle upgrade hints and gradually increase conversion prompts as users invest more time and effort into the product.
Why this can grow a startup
Users build investment and switching costs before hitting any hard paywall. By the time they reach limits, they already see clear value in upgrading rather than abandoning the tool. The Good analyzed 15 top AI tools and found this pattern consistently among the highest-converting products. It avoids the common mistake of going straight to hard limits, which loses users who might have converted with a gentler ramp.
Company example
Claude (gentle limit notifications escalating to hard upgrade push), ChatGPT (multiple contextual upgrade CTAs at file upload and advanced features), Perplexity (remaining query count shown per search).

When to use it
Use this when Referrals is relevant to 0-100, 100-1K and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
Founder checklist
- Read thegood.com and identify what is directly supported.
- Choose one channel context: Referrals.
- Define the test around one observable customer behavior.
- Set an owner, evidence window, and stop condition before launch.
