Show HN: Free open-source churn prediction for SaaS–Stripe and LLM interventions

Took a quick look and I liked the it. I will be using it for my own saas applications.

Thanks for creating this project. Will give it a star.

Hey HN — built this because every churn prediction notebook on GitHub uses the Kaggle Telco dataset and outputs a confusion matrix that no founder can act on.

ChurnGuard connects to your Stripe account, engineers behavioral features from real billing data, trains an XGBoost model on your actual churned vs retained customers, and uses SHAP to explain why each customer is at risk in plain English.

The LLM layer (Groq free tier) generates a specific 30-day retention playbook per at-risk customer — not "schedule a call" but actual messaging, offer amounts, and who should own each action.

Entire stack is free. Works in Google Colab. Happy to answer questions about the architecture.
