Stop losing customers to silent churn
Your customers aren't leaving because they hate your product. They're leaving because you charged them full price for a month they barely showed up. RetAIn fixes that.
No credit card. No spam. First 50 founders get in free.
How RetAIn works
Three steps. No billing migration. No rebuilding anything.
Set your base fee
Your revenue floor, always guaranteed. It covers what it costs to run their account — servers, support, nothing more.
RetAIn tracks usage
Simple REST API integration. A few lines of code and you're live. Most teams ship it in a weekend.
Bill matches reality
Base fee + actual usage, capped at your full price. Heavy users pay full. Light users pay less. Nobody has a reason to cancel.

- No warning before cancellations
- Lost forever over a fixable billing problem
With RetAIn
