Reach out within 24h — the next 48h are decisive.
Most churn is preventable. You just see it too late.
The signals are already in your Stripe data. They're just buried under invoices.
You discover churn weeks late
A cancel email arrives. Then maybe a Slack DM from someone on your team. Then the Stripe notification. By the time it lands in your inbox, the customer mentally left 3 weeks ago.
What this costs
Every week of delay = one less chance to save the account.
Failed payments slip through
Stripe retries, gives up, deletes the subscription. Nobody told you to send a card-update link in time.
Disputes blindside you
A chargeback hits your inbox like a wall. The customer is already gone — and you don't know what triggered it.
Your team can't prioritize
Three customers in trouble, one founder. Without a clear signal, you waste the morning deciding instead of acting.
You guess at the next action
Even when you spot a risk, you stare at the page wondering: email? discount? call? You waste days deciding.
Built for revenue owners, not analytics teams.

Questions you probably have
Do you need write access to my Stripe account?+
No. ChurnKiller uses Stripe Connect with read-only OAuth. We can read subscriptions, invoices, and events — we cannot charge, refund, cancel, or modify anything in your account.
Do I need to install anything in my app?+
Nope. ChurnKiller works purely from Stripe data. No SDK, no script tag, no code change in your product. Just connect Stripe and we surface the signals already there.
How is this different from a CS tool like Vitally or ChurnZero?+
Those tools assume you have a customer success team running them. ChurnKiller is built for the founder who is the CS team. Smaller, sharper, action-first. Pings you on the moments that actually matter.
Why Slack, not email?+
Founders live in Slack, not in inbox. A Slack ping at 11am gets actioned the same morning — an email digest gets opened next week.
Is it free?+
Free during beta while we calibrate the scoring on real data. Pricing will land later — fair, transparent, and tied to how many customers you analyze.
What about my customers' data privacy?+
We only sync subscription metadata (status, MRR, plan, payment events). We never see card numbers, full invoices, or PII beyond email and name. All data is encrypted at rest, and you can disconnect Stripe in one click — your data leaves with you.
Stop reacting too late.
Connect Stripe and see your revenue at risk in 2 minutes.
