CONNECT YOUR CONTEXT · AND WHY IT HELPS
a CRM

it reads churn, downgrades, renewal dates, and notes automatically, across the whole book.

a product-analytics tool

adds usage decline, the single strongest churn tell, so a quiet account gets caught before the renewal call.

a support or ticketing tool

adds ticket volume and sentiment, so a frustrated account surfaces early.

SET IT TO YOUR MOTION

This was built for a B2B SaaS org with recurring subscriptions. Set these to your stack:

Run any churn taxonomy you like. The skill groups your churn into your themes and scores your active book against them, so point it at your fields, not anyone else's.

03 / THE FULL SKILL

Everything the skill does, in full.

── WHAT THIS DOES

Reads your churned and downgraded accounts and pulls out why they left: the themes, the shared conditions, the moments it started slipping. It turns those causes into an early-warning checklist, then runs that checklist across your active book and flags the customers who look like the ones that just walked. The point is not a churn number for the board. It is a short list of current accounts to save while there is still time.

── THE METHOD
  1. 1
    Churn theme extraction

    Group every churned and downgraded account across reason, segment, tenure, value, and (if connected) usage. Report only the themes that clear MIN_SAMPLE. For each theme, show the share of churn, the revenue behind it, and the average tenure at churn, so a high-count theme and a high-dollar theme are both visible. Treat a downgrade as churn's early cousin, not a separate story: the same causes usually run underneath.

  2. 2
    Cause vs symptom

    Separate what you can see from what actually drove it. A dead login count is a symptom. The cause is usually one of a few things: the champion left, the value was never realized, onboarding stalled, a merger or budget cut hit, or a competitor displaced you. Name the cause, because the checklist has to catch the cause early, not the symptom at renewal.

  3. 3
    Early-warning checklist

    Turn the top causes into a short list of observable signals that appear before churn, not at it: usage down X percent over N weeks, champion gone quiet or departed, no executive contact in the last quarter, support tickets spiking, a renewal inside 90 days with no engaged buyer. Each signal is something you can check on a live account today.

  4. 4
    Predictive read (active book)

    Run the checklist across your active accounts and score each one by how many warning signals it hits. Return a ranked watchlist, highest risk first, with the exact signals each account trips and how closely it resembles a specific churn theme. This is the payoff: the accounts to save this quarter, named, before the renewal call.

── QUALITY GATES
  • No theme reported below MIN_SAMPLE. One angry cancellation is not a pattern.
  • Usage-decline claims show the trend, not a single reading. A quiet week is not churn.
  • Every at-risk account lists the specific signals it trips, never just a risk score.
  • Cause is grounded in a field, a note, or a usage trend, never assumed from the logo.
── OUTPUT (EXAMPLE)
EXAMPLE OUTPUT
CHURN ANALYSIS · 23 churned + downgraded, trailing 4 quarters

Churn themes
Theme                        Share   Revenue    Avg tenure
Champion left, no backup     35%     $180K      14 months
Never reached first value    26%     $130K      7 months
Price at renewal             22%     $95K       22 months
Merger / budget cut          17%     $70K       19 months

Early-warning checklist (the signals that came first)
  [ ] Usage down 40%+ over trailing 8 weeks
  [ ] Champion departed or dark 60+ days
  [ ] No exec contact in the last quarter
  [ ] Renewal inside 90 days, no engaged buyer
  [ ] Support tickets spiking

Active accounts that look like recent churners (highest risk first)
Account      Signals tripped                 Resembles
Kestrel Co   usage -52%, champion dark        "champion left"
Alderman     onboarding stalled, low usage    "never reached value"
Pentworth    renewal in 60d, no buyer         "price at renewal"

Next move:
  1. Kestrel. Find a second champion now. The first one is gone.
  2. Alderman. Restart onboarding before renewal. It never got to value.
  3. Add a usage feed. It is your single strongest early tell and it is missing.
── WHERE THE NUMBERS COME FROM

MIN_SAMPLE (5), the trailing-4-quarter window, and the usage-decline cutoffs are defaults, not laws. They suited a subscription business with steady churn volume. If you churn a small number of large accounts, widen the window so the themes are not built on a handful of exits. Usage thresholds should match your product's natural rhythm: a weekly tool and a quarterly tool decline differently. The checklist is always built from your own churn, so it warns you about your accounts, not a benchmark's.

We lost 23 accounts over the last year. What do they actually have in common? Here's the export. [pastes CSV]
CLAUDE
Four real themes, not a grab-bag of reasons. Theme Share Revenue Avg tenure Champion left, no backup 35% $180K 14 months Never reached first value 26% $130K 7 months Active accounts that look like recent churners Account Signals tripped Resembles Kestrel Co usage -52%, champion dark "champion left" The payoff isn't the churn report, it's Kestrel. It hits two of the same warning signals that show up before "champion left, no backup" churn, and it's still active. That's a save attempt you can make this week instead of a postmortem you write in six months.
You
What should the team actually check on Kestrel right now?
CLAUDE
Find a second champion before the current one is fully gone, that's the exact gap the "no backup" theme names. One sharpener: connect your product-analytics tool so usage decline reads as a trend across weeks instead of the single data point in this export, a quiet week and a dying account look identical without it.
04 / GO FURTHER

Where an operator takes this next.

Running the postmortem by hand catches this year's pattern. Here's how it starts catching next year's churn before it happens.

Catching the pattern once is a report. Watching for it every week is retention.

01
Score the active book weekly

Connect Salesforce and Amplitude to a scheduled Claude task that reruns the early-warning checklist against every live account every Monday, not just when someone remembers to ask.

02
Alert on the signal, not the renewal date

Wire a Slack message to the account owner the moment an account trips two or more warning signals, so the save attempt happens in month two, not the renewal call.

03
Feed saves back into the theme

Log every successful save in a data store so the checklist itself improves: which signals actually predicted churn versus which ones were noise.
