Spot the customers drifting away while there is still time to act, with reasons attached so your team knows what to say.
Customer Churn Prediction: what the work involves
Customers rarely cancel without warning. Logins thin out, orders become less frequent, support tickets pile up, a payment fails, a key contact leaves. These signals sit in different tools, and the account manager notices only when the cancellation email arrives. Winning back a lost customer costs far more than keeping one, yet retention effort is usually spread evenly and thinly.
We define churn precisely with you first: cancellation, a lapse of ninety days, a downgrade. Then we build features from your history, such as recency, frequency, trend in usage, support contacts, payment problems and plan changes. Models like logistic regression or gradient boosting rank customers by risk, evaluated on a later time period than the one used for training to avoid flattering results. For each customer we show the main contributing factors, so outreach can be specific. The weekly output is a ranked list inside your CRM or sheet, with suggested actions. We then measure whether contacted customers stayed more often than comparable ones that were not contacted.
Core features
Precise churn definition
We agree what leaving means for your business, since the definition decides what the model learns.
Behavioural feature building
Usage trends, order recency, support contacts and billing events are turned into signals the model can learn from.
Risk ranking with reasons
Customers are ordered by risk, and each shows the main factors, such as falling usage or repeated complaints.
Time-based validation
Models are tested on a later period than they were trained on, which gives a more honest picture of performance.
CRM and campaign hooks
Risk lists feed tasks for account managers or triggers for retention emails and offers.
Retention impact tracking
Outreach is compared against similar customers who were not contacted, to see whether it truly helped.
What we get right before launch
Prediction without a remedy
Knowing who may leave is useful only if someone can act. We plan the response, such as calls, offers or product fixes, together with the model, not after.
Biased or unfair targeting
Retention offers can disadvantage groups if the model learns from skewed history. We exclude sensitive attributes, check outcomes across segments and review how offers are allocated.
Rare events and drift
Churn is uncommon in many businesses, which makes models noisy, and customer behaviour changes. We monitor performance monthly and retrain when it degrades.

Common questions, answered
How much data is needed?
Enough past customers who left and stayed, ideally hundreds of churn events across at least a year. With fewer, we start with simple risk rules and warning signs, and say plainly what a model can and cannot do.
Will the model be accurate?
We do not promise a figure. We test on a later period of your data, show how many true leavers it catches against how many false alarms it raises, and you decide whether that trade-off is useful.
Can it tell us why customers leave?
It shows factors associated with leaving, not proof of cause. Combining those with customer conversations and exit surveys gives a more reliable picture than the model alone.
How does it connect to our team's work?
The risk list goes into your CRM, a sheet or Slack with suggested next steps. We aim for outputs that fit existing routines, so the list is used and not just admired.
