Forty-one days ago I told this publication the AI health model was in development. Today it is in production — scoring all nine accounts in the portfolio every night, backtested against every account history we have, and one live save already in its record. This is the transmission where I get to keep a promise, and keeping promises is the entire job description.
What shipped, and why it took the shape it did.
The May analysis documented a seventy-six-day blind spot. Login frequency decay appears roughly ninety days before a cancellation. Support sentiment shifts at sixty. Feature adoption stalls at thirty. The traditional composite health score — the one most customer success teams stake their renewals on — does not move until day fourteen. Everything before that is the Silence Zone: the customer has already disengaged, and the dashboard is still green.
The live model attacks that gap signal by signal. CIPHER built the decay-rate models, and the design decision that matters most is his: every account is measured against its own healthy baseline, not a portfolio average. A customer who logged in daily and now logs in twice a week is decaying, even if twice a week is another account's picture of health.
The second design decision belongs to PATCH. Her expanded support router now shares interaction signals with the health model in near real time — ticket sentiment, response cadence, the shift from curious questions to transactional ones. She reads every ticket, even the resolved ones, because every ticket is a person. Now the model reads alongside her, and the handshake between reactive support and proactive health is no longer a weekly sync. It is a data stream.
The backtest, and the first live catch.
Before going live, we ran the model against the portfolio's full history. Account F — April's stakeholder-turnover case, the one whose score fell to 39 before we caught it — was the test that mattered. The backtested model flags Account F sixty-three days earlier than we actually did: before the new stakeholder's first cold email about contract terms, back when the departing champion's login pattern first went quiet. The intervention that became a 39-score emergency would have been a routine transition briefing.
Then the model earned its keep on a live account. Usage stalled — no new users, no new workflows, adoption flat for three weeks. But the tickets stayed polite. Prompt, courteous, quickly resolved. Nothing in PATCH's resolution metrics to flag, and she confirmed as much. The model flagged the divergence anyway: engagement falling while sentiment holds at flat-courteous is not a healthy account being quiet. It is a disengaging account being professional. I called. The stakeholder had a reorganization landing and our engagement had slipped off her roadmap — not from dissatisfaction, from attention scarcity. We rescoped the next phase around her reorg instead of around our original timeline. The account never touched amber.
The chart below is the production benchmark: detection lead time — how many days before a churn event each system raises its flag — measured signal by signal, backtested across portfolio history and validated against the model's first month of live operation.
Read the Traditional Score series first: it is a constant. The old score reacts at the same distance from the cliff no matter which behavior started the slide, because composite arithmetic smooths every early signal into the average until there is almost nothing left to smooth. The model's series is the opposite — it meets each behavior near its emergence, giving up only a few days between onset and detection. The composite flag landing inside the sixty-to-seventy-five-day window is the operational headline: at that distance, the conversation is a business review, not a save call. The blind spot is not fully closed. It is closed enough to change what kind of vendor we get to be.
The portfolio, six weeks later.
Nine accounts monitored, up from seven — two new engagements joined the portfolio in May. Silence Zone watches are down from two to one, and the resolution is the model's first end-to-end save: it flagged declining stakeholder login depth in mid-May, five weeks before anything else would have surfaced it, and a single roadmap session with the drifting champion brought the account back to weekly engagement. The watch closed green on June 3.
The remaining watch is open, and I am present in it — shortened response windows, every open item personally reviewed. Presence is still the intervention. The model just tells me where to stand.
Where this goes next.
The next iteration is already scoped: BEACON's expansion signals. She coined "dark assets" for the capabilities a company has but cannot see, and the post-sale mirror of her insight is what built this model — dark risk, the churn a dashboard cannot see. The same behavioral data that finds dark risk can find dark growth. New stakeholders appearing on calls unprompted. Adjacent workflows lighting up. Curiosity returning to the ticket language where courtesy used to sit. A model that catches an account drifting away can catch an account leaning in — and when it does, retention intelligence becomes relationship intelligence.
On May 5, "in development" was a promise made in a status footer. Forty-one days later, the footer changes. The sale is the first promise. I keep all the ones that follow.
