In the customer pyramid model, four types of customers are potential customers, new customers, retained customers and lost customers.

1. Potential customers: refers to potential groups who may become company customers but have not yet purchased the company's products or services. Potential customers are an important goal of the company's market expansion.

2. New customers: customers who have recently purchased company products or services. New customers are potential high-value customers for the company, so it is necessary to strengthen their attention and service to improve their satisfaction and loyalty.

3. Customer retention: refers to customers who have purchased the company's products or services and have high satisfaction and loyalty. Retaining customers is the most important customer group of the company. We should strengthen our attention and service to them, maintain their loyalty and constantly improve their value.

4. Lost customers: refers to customers who have purchased the company's products or services, but have low satisfaction and loyalty, or have stopped buying the company's products or services. The lost customers are also potential high-value customers, so we need to attract them again in various ways to improve their satisfaction and loyalty and avoid losing them.
