Final answer:
The third stage in the Customer Life Cycle of a company is Growth, where a company increases the value of its existing customers.
Step-by-step explanation:
When examining the Customer Life Cycle in a company, the third stage is typically considered to be growth. The full cycle often consists of the following steps: Acquisition (where new customers are obtained), Retention (the stage where the company works to keep their customers engaged and satisfied), Growth (in this stage, the company aims to increase the value of existing customers often through upselling or cross-selling), and finally Advocacy (where satisfied customers promote the company or product to others).
