Any business wants to maximize the number of customers. To achieve this goal, it is important not only to try to attract new ones, but also to retain existing ones. Retaining a client will cost the company less than attracting a new one. In addition, a new client may be weakly interested in business services and it will be difficult to work with him, while old clients already have the necessary data on interaction with the service.

To help the business, I can predict the churn and can react in time to keep the client who wants to leave. Based on the data about the services that the client uses, I can make him a special offer, trying to change his decision to leave the operator. This will make the task of retention easier to implement than the task of attracting new users.
