About

Churn Buster is a subscription retention software company that recovers failed payments and prevents cancellations for subscription eCommerce and SaaS businesses. It offers two products that run together or separately. Dunning coordinates retries with branded email and SMS that ask the customer to update their card, and on platforms where Churn Buster runs the retries, it controls their timing. Cancel Flows replaces a one click cancel with a short flow that offers a pause, skip, discount, or plan swap, asks why the customer is leaving, and includes a click-to-cancel option for regulated locations. Churn Buster has handled 50+ million failed payments since 2013, and its retention team has tuned the retry and campaign defaults across 1,000+ accounts. Dunning works with Stripe, Braintree, Recharge, Loop, Skio, Stay AI, Checkout Champ, Seal Subscriptions, Ordergroove, and other subscription platforms. Pricing starts at $269/mo, a flat fee by MRR tier, month to month.

About

Rezup tells SaaS and subscription businesses why customers cancel, in the customers' own words. Connect Stripe with a restricted, read-only key. When someone cancels or downgrades, Rezup sends them one short email from your name, 5 minutes to 24 hours later. The customer opens the link and answers by voice or text, in any of 120+ languages, with no app or account. Every answer is transcribed and translated into your language. AI groups the answers into reasons and ranks them by the MRR behind each, shows which reasons are growing, and suggests a next step. If the customer picked a reason in Stripe's cancel form, Rezup uses it too. You get a weekly summary by email, alerts in Slack or Telegram, and you can reply to unhappy customers from your own email. Not on Stripe? Share the same question as a link, QR code or website widget. Free up to $5k MRR (50 responses a month), with AI analysis on every plan.
