You find out a user churned.
After they already cancelled.

By then there's nothing you can do. The window closed days ago — and you had no idea it was open.

🕳️

Churn happens silently

Users don't send a farewell email. They just stop logging in, stop using your core features, and one day — they cancel. You only see the number drop.

The intervention window is short

Research shows 60–70% of SaaS churn happens within the first 30 days. Miss that window and no amount of winback email sequences will bring them back.

📊

Dashboards don't tell you what to do

You have analytics. You have MRR graphs. But none of it says "contact this specific user, right now, before they leave." That gap is costing you revenue every week.

From setup to first insight
in under 5 minutes.

One snippet. No complex integrations. No engineering sprint.

01

Add one line of code

Paste the Churnox snippet into your app — or connect via our Stripe webhook in one click. Churnox starts tracking the behavior signals that actually predict churn: login frequency, feature usage, session duration, pricing page visits, payment failures.

Setup: ~4 minutes
02

Every user gets a live risk score

Churnox scores each user from 0–100 based on four signal layers: behavioral, financial, support, and timing. The score updates daily. A user who stopped using your core feature and just visited your pricing page for the third time this week? That's a 78.

Updated daily · no manual work
03

Get a weekly "who to contact" briefing

Every Monday you get an email: here are the 3 users most likely to churn this week, here's why, and here's the message we suggest sending. No dashboard-staring required. The briefing comes to you.

Email-first · works even if you never open the dashboard
04

Get instant alerts when it's urgent

Payment failed? 12-day silence before renewal? Churnox fires an instant Slack or email alert with a ready-to-send intervention message. The difference between a saved user and a churned one is often a single well-timed email.

Instant alerts · Slack + email

Four layers of churn intelligence.

Most tools show you one metric. Churnox combines four signal types to catch at-risk users others miss.

Behavioral signals

Login frequency drop, core feature usage stopping, session duration falling below baseline, onboarding left incomplete after 14 days.

Highest weight

Financial signals

Payment failure via Stripe webhook, repeated visits to the pricing or cancellation page, plan downgrade attempts, failed card retries.

High weight

Support signals

Multiple support tickets in a short window, negative sentiment in chat or email, unresolved complaints older than 7 days.

Medium weight

Timing signals

Renewal date within 7 days combined with low activity in the preceding 14 days. First 30-day window without activation.

A score tells you where to look.
Churnox tells you what to do.

Every user gets a 0–100 risk score updated daily. When someone crosses 60, you get a suggested action — not just a number.

Under 30 — healthy, no action needed. Maybe an upsell opportunity.

30–60 — watch closely. A check-in email can prevent further drop.

61–100 — intervene now. Churnox surfaces the reason and drafts the message.

"I used to find out someone churned when I saw MRR drop on Monday morning. Now Churnox tells me on Thursday who's at risk. I've saved 3 accounts this monthwith a simple email."

"The payment failure alert saved us $800 in one afternoon. User's card was failing, they hadn't noticed. Churnox pinged me, I sent one email, they updated their card. Would have churned otherwise."

Questions we get a lot.

How accurate is the churn prediction?
In the first weeks, Churnox uses a rule-based model with four signal layers — expect around 65–75% AUC-ROC accuracy. That might sound modest, but your current prediction accuracy is likely 0%. As data accumulates over 3–6 months, accuracy improves significantly. More importantly: we tell you to act 7–14 days before a user churns. That window matters more than the exact percentage.
Do I need to be technical to set this up?
No. If you can paste a line of JavaScript into your app, you're done. If you use Stripe, connecting via webhook takes about 90 seconds. There's no SDK to configure, no data schema to design, no engineering sprint required.
What if my users aren't logging in much anyway?
Churnox adapts to your users' baseline. If your product is naturally weekly-use, a 10-day gap doesn't trigger a high risk score. The signals are relative to each user's own history, not absolute thresholds.
Is my users' data safe?
Churnox stores behavioral metadata only — event types, timestamps, and counts. We never store the content of your users' sessions, messages, or documents. Data is encrypted at rest and in transit. We don't sell or share any data.
Can I cancel anytime?
Yes, always. No annual commitment, no cancellation fee. If you cancel, you keep access until the end of your billing period.
