Keeping Customers: Most startups forget that it is much more expensive to get than to keep a customer. Retaining a customer or ensuring that a customer doesn't churn is therefore the major business objective to keep customers. The Key Metric of the Keep Customer Phase is Churn.
Growing Customers: Growing the customer finally maximises the Gross Profit return (which is revenues minus Cost of Goods Sold) over the entire future relationship with a customer (the customer lifetime). The key metric is the Customer Lifetime Value (CLV or often CLTV).
