Their Pitch

Boost retention. Slash churn. Accelerate growth

Our Take

It's a pop-up that intercepts customers trying to cancel and throws discount offers at them. Like a digital bouncer for your subscription exit door.

Deep Dive & Reality Check

Used For

  • +**Customers hit cancel and disappear forever** → Pop-up survey captures why they're leaving, offers discount/pause, saves 20-40% who would've churned
  • +**You're flying blind on cancellation reasons** → Real-time dashboard shows sentiment trends and feedback patterns instead of guessing
  • +**Manual retention emails sent too late** → Automated offers trigger at the exact moment of cancellation when you can still save them
  • +Drag-and-drop flow builder - no developers needed to customize surveys and discount offers
  • +A/B tests different retention offers automatically to find what actually keeps people subscribed

Best For

  • >Your Stripe dashboard shows dozens of silent cancellations every week
  • >Customers vanish without telling you why they're leaving
  • >You're bleeding $5K+ monthly recurring revenue to quiet quitters

Not For

  • -Solo developers with under 100 subscribers — the setup cost probably exceeds what you'd save
  • -Companies wanting full churn prediction — this only catches people already hitting the cancel button
  • -Teams that prefer building custom retention flows — you're paying for no-code convenience you won't use

Pairs With

  • *Stripe (where the cancellation webhooks trigger and billing changes actually happen)
  • *HubSpot (for following up with customers who still churned despite the retention offer)
  • *Slack (where your team gets alerts about cancellation reasons and successful saves)
  • *Salesforce (to track which customer segments are most likely to accept retention offers)
  • *Intercom (for proactive outreach to customers showing similar cancellation patterns)

The Catch

  • !No public pricing means you're going in blind on costs until you request a demo
  • !Only works at the point of cancellation — won't help with customers who ghost without trying to cancel
  • !Limited real user feedback available — mostly vendor testimonials and a handful of G2 reviews

Bottom Line

Turns your cancel button into a last-ditch negotiation that actually works.
