Mathematical models to reduce customer churn rate

In synergy with one of the main operators of the free market of electricity and natural gas, we worked to understand the causes of churn, i.e. the rate of abandonment by customers, and allow customer service to implement targeted actions of prevention and refinement of the offer.

  • Description and benefits
More effective retention actions
Objective and data-driven analyses
Increased quality of the service offered
