B2B Customer Churn Modeling

Built a customer churn prediction model on a 4 person team for Cox Automotive. Used an Explainable Boosting Machine with expanding window temporal cross validation, optimizing for PR AUC and lift at the top decile while keeping every feature interpretable for stakeholder review. Engineered role segmented features across engagement, tenure, and product usage; tuned thresholds against retention intervention costs. Delivered to Cox stakeholders to inform account management prioritization for at risk customers.
