RetAIn

What it does

RetAIn fixes the billing problem behind silent churn. Light months cost less. Heavy months hit full price. Nobody cancels because of a slow month again.

RetAIn eliminates silent churn for SaaS. Customers pay based on actual usage, capped at full price. Light users pay less — nobody has a reason to cancel.

Most teams ship it in a weekend. Base fee + actual usage, capped at your full price. Heavy users pay full. Light users pay less. Nobody has a reason to cancel.
