A customer logs in less.
They were a daily user. Now it's every other day. Then weekly. Most tools don't see this because most tools don't look at it.
Case study · product
Ebb.
Customers don't churn — they ebb.
A churn-prevention tool for Stripe-powered businesses. Most churn tools tell you after a customer cancels. Ebb watches your Stripe data for the quiet behavioural signals that show up 14–30 days earlier, and sends you a weekly digest of who to save and how.
The problem
By the time they cancel, they already left.
Reactive churn tools detect cancellations after they happen. By then, the customer made the decision weeks ago — you're just reading the timestamp. The save-window has closed.
They stop using the sticky feature.
The one workflow they used every Monday — gone for three weeks. Their last support ticket reads a little tense. Card expires next month.
They cancel. You get an email.
Your reactive churn tool fires off a slick exit survey. They tick “not the right fit” and never reply. The MRR's already gone.
Ebb watches the boring middle — the days nobody else looks at — and tells you which customers are quietly drifting away while there's still time to do something about it.

Three steps. Ten minutes.
No SDK. No engineering project. Connect Stripe and Ebb starts watching.
Step 1read-only
Connect Stripe.
OAuth in two clicks. Ebb reads subscription, invoice, and customer data — never charges, never writes.
Step 2every 24h
Ebb watches the signals.
Login frequency, feature usage, support sentiment, payment health, plan changes. Scored and updated daily.
Step 3Mon · 08:00
Weekly digest lands.
Mondays at 8am: who's drifting, why, and the one move most likely to bring them back. Three minutes to read.
