Usage-based billing that ends silent churn - RetAIn

Hey PH 👋 I built RetAIn because I kept watching SaaS founders lose customers they should have kept. Not because the product was bad. Not because support failed. Because they charged full price for a month the customer barely showed up — and that customer quietly decided renewal wasn't worth it. Silent churn. No complaint. No warning. Just gone. The fix is simpler than most people think. When a slow month produces a smaller bill, there's nothing to resent. No accumulated frustration. No cancellation at renewal. RetAIn sits between you and your billing — tracking actual usage each month and calculating a fair bill automatically. Base fee plus usage, always capped at your full subscription price. Heavy users pay full price. Light users pay less. Nobody has a reason to cancel. Even Stripe's team said it publicly on r/SaaS: "Customers paying for unused capacity churn. Hybrid billing fixes it." That's exactly what RetAIn does. Happy to answer anything — would love to hear if this resonates with what you've experienced in your own SaaS.
