Airdun is an automated recovery system for SaaS businesses billing on Stripe. When a subscription payment fails, whether from an expired card, insufficient funds, a generic decline, or an incomplete 3D Secure authentication, Airdun opens a case and works it across email, SMS, WhatsApp, and an in-app wall, until the invoice is paid or written off.

Connect Stripe, pick what Airdun should recover, and put it live.

Get started

1

Get your free recovery report

Connect your Stripe account to Airdun. Airdun reads your invoices, customers, and subscriptions, and shows a report of your last 90 days: payments lost, payments still failing, and your current recovery rate.
2

Pick your use cases and follow the checklist

Pick what Airdun should recover (Renewals, Free trials, New customers) and complete the setup checklist: Stripe retry policy, Recovery Profile, sending domain, business context, and each use case’s messages and settings.
3

Go live

Put each use case live. From then on, every new failed payment of that kind opens a case Airdun works on its own.
Airdun is available on the Stripe App Marketplace. Recovery messages are sent from your domain and under your brand name.

​
Why Airdun

Every failure has a different cause and deserves a different response. Airdun handles each case on its own, within the rules you set, instead of sending everyone the same sequence.
