Sellers show you 2.3% logo churn and a clean cohort chart. The raw CSV tells a different story. We find the gap — before you wire the money.
Normally $49. One full Pro report. Money-back if we miss a red flag.
SaaS sellers optimize metrics for the pitch deck. Logo churn gets massaged. Revenue concentration gets buried. Annual-plan decay gets ignored. You inherit the mess — and you pay for it.
In 2022, I was 48 hours from wiring the money. The seller's deck showed 2.3% monthly churn. Clean cohort charts. "Sticky" enterprise logos. Everything checked out — on paper.
Three months post-close, renewals collapsed. Annual-plan customers walked. Two whales went dark. The "2.3%" was logo churn across a tiny base. The real revenue churn was 9.4%.
I didn't buy a SaaS business. I bought a leaking bucket — and it cost me $340,000 in lost value.
→ So I built the tool I wish I'd had.
"The number wasn't hidden in some secret database. It was sitting in the raw Stripe CSV the entire time. I just didn't know which six columns to look at — or that I even should look."
That CSV is the only source of truth. ChurnLens reads it so you don't have to.
Each one is a question sellers hope you never ask. Our report answers all six — directly from the raw data. No guesswork.
The deadliest metric sellers hide. Compares logo churn vs. revenue churn — wide gaps reveal accounts bleeding cash even as headcount holds steady. This is the gap that cost us $340K.
Quantifies exactly how much of MRR sits with your top 3 accounts. A single whale leaving shouldn't erase your entire margin of safety.
Annual subscribers are ticking time bombs at renewal. We model who's likely to cancel — and when — so you price that risk into the deal before you close.
Paying customers who haven't logged in for 90+ days. Revenue that looks alive but is already dead. We flag every zombie dollar so you don't pay a multiple on it.
Composite A–F grade weighing retention, concentration, expansion, and growth trends. One letter that tells you whether to walk or wire.
Separates new sales from declining cohorts. Headline MRR can be flat while the underlying base deteriorates. We show you both lines — the story behind the story.
Here's what getting it wrong actually costs. Compared to what ChurnLens costs.
| Cost of Getting It Wrong | Estimated Damage |
|---|---|
| Overpaying by 20–40% on a $500K deal | $100,000 – $200,000 |
| Lost ARR from undetected churn (year 1) | $45,000 – $95,000 |
| Whale customer departure within 6 months | $60,000 – $150,000 |
| Opportunity cost — capital tied up in a lemon | Priceless |
| ChurnLens full risk report: $9 (normally $49) | |
$9 to avoid a $100K+ mistake. That's the math.

Here's how confident we are: if our report misses a churn divergence, a concentration risk, or a revenue decay signal that later costs you money — we refund your payment. No hoops. No "credit toward next month." Just your money back.
The risk is on us. Not on your deal.
Ran a ChurnLens report on a deal I was about to close. Found a 5.7-point churn divergence and a whale that was 40% of revenue. I walked. Three months later that whale churned. The buyer who replaced me is now underwater.
SaaS Acquirer, MicroPE Fund
I used to spend 15 hours in Excel trying to reverse-engineer churn from a seller's CSV. ChurnLens does it in under a day and catches things I'd miss — especially the annual-plan decay modeling. It's now part of every LOI checklist.
M&A Analyst, Tech Holdings
The zombie MRR detector alone paid for a year of the Pro plan. Found $9K/month of revenue from accounts that hadn't logged in for 120+ days. Renegotiated the deal price by $75,000.
