Most SaaS products let subscribers cancel with a single click. No conversation, no offer, no chance to understand why. 20-40% of those customers would have stayed if you just asked. MRRX sits between your cancel button and Stripe. When a subscriber tries to cancel, they hit a hosted retention flow with offers you configure — pause, discount, downgrade, or extend trial. One API call. 5-minute setup. Flat pricing at $79/mo. No percentage of saved revenue. Free 30-day pilot.
