Stop losing customers
you already won
Sound familiar?
You open Stripe and another one's gone
No warning. No signal. Just a cancelled subscription and the sinking feeling you could've saved it — if you'd known a week ago.
Meanwhile, failed payments are silently eating your MRR. 40% of SaaS churn is involuntary — cards expiring, payments bouncing — and most founders don't notice until the revenue is already gone.
ChurnFast watches so you don't have to.
- Scores every customer 0–100 based on real billing and usage signals — not gut feeling
- Flags at-risk accounts up to 30 days before they cancel
- Catches failed payments instantly and starts dunning automatically
73% of churning customers have already decided to leave before they actually hit cancel. The window to save them is small — but it exists.

Features
Everything you need to reduce SaaS churn automatically
Churn Risk Scoring
Our ML model analyses 50+ behavioural and billing signals to score every customer 0–100. Each score includes a full factor breakdown so you know exactly why a customer is flagged — no black boxes.
Revenue Impact
See exactly how much MRR is at risk and prioritise outreach by dollar value. Recovering just 3 churned accounts per month typically pays for an annual ChurnFast subscription.
Behavioural Tracking
One script tag. Under 8KB. Tracks sessions, feature usage, rage clicks, and engagement trends — zero performance impact. Research shows a 30% drop in feature usage is the earliest reliable churn signal.
Billing Data
Connect your Stripe account and webhooks are configured automatically. Failed payments cause up to 48% of all SaaS churn — ChurnFast flags them instantly so you can recover revenue before it's lost.
Payment Dunning
Recover failed payments before they become churn. Build and customise dunning email sequences with our visual editor, using merge tags to personalise every message. Engagement-aware variants automatically adapt tone based on customer health.

Howdy, fellow churn fighter
While digging into my own Stripe data and acquisition channels, I noticed something frustrating. I could see where paying customers came from — but I had no way of knowing which of them were about to leave. The retention side of the equation was completely missing.
I'd check Stripe and discover someone had churned days ago. Every tool that promised to help was built for funded startups — $75–$760/month, complicated dashboards, and more metrics than any solo founder could act on.
“I know how to get customers — but I can't see when they're about to leave?”
That gap became ChurnFast. Stripe-native churn intelligence — built for solo founders who fought hours for every dollar of MRR and shouldn't lose it in silence.
So I built ChurnFast for 3 reasons:
- 1.Predict churn before it happens using research-backed signals, not guesswork.
- 2.Show you who's at risk — with clear scores and the signals behind them.
- 3.Price it for solo founders: $19/month. That's it.
I'm building ChurnFast in the open. Let's ship!
