Background

FinGrow provides automated accounting software for small businesses. Operating on a subscription model, their growth relied heavily on Customer Lifetime Value (LTV). While they were excellent at acquiring new customers through aggressive marketing, they suffered from a “leaky bucket” problem losing a significant percentage of users after the three-month mark. Their data team had millions of rows of usage logs but lacked the infrastructure to turn that raw data into actionable retention strategies.

The challenges

The VP of Growth, Marcus Thorne, realized that their retention efforts were reactive rather than proactive. They were sending “We miss you” emails after a customer had already cancelled. By then, it was too late. The company needed a way to identify at-risk customers before they hit the cancel button. They required a machine learning solution that could analyze user behavior patterns like login frequency drops or unanswered support tickets to flag high-risk accounts in real-time.

We were bleeding revenue and didn’t know why. The predictive model didn’t just give us a list of names; it gave us the ‘why’ behind the churn, allowing our success team to intervene with surgical precision.

The Solution

We engineered an end-to-end churn prediction pipeline using Python, XGBoost, and AWS SageMaker.

We aggregated disparate data sources (app usage logs, billing history, and Zendesk support tickets) to create a rich feature set, identifying key indicators like "days since last login" and "sentiment score of last support ticket."
We trained and fine-tuned an XGBoost classifier, achieving a 92% accuracy rate in distinguishing between retained and churned users on historical data.
Instead of a static report, we built an API connector that pushes a "Risk Score" directly to the customer success team's CRM every morning. If a high-value client's risk score spikes, the account manager gets an immediate Slack alert.

The Result

FinGrow moved from a reactive “damage control” strategy to a proactive “success” strategy.

By intervening with targeted discounts and training sessions for at-risk users, the company reduced overall churn by 28% within the first quarter.
The Customer Success team stopped wasting time calling happy clients and focused 100% of their energy on the clients who actually needed help.
The model's "feature importance" output revealed that a specific confusing UI element was a leading cause of churn, leading to a targeted product redesign that permanently fixed the issue.
