The essential definition of CSM
CSM (Customer Success Management)It is a customer-centric management philosophy and system that focuses on proactively understanding and driving customer experience, helping users obtain clear and continuous value from products and services, thereby increasing user stickiness and business returns. Unlike traditional customer service and after-sales support, the CSM team takes a "prevention is better than cure" approach throughout the entire customer lifecycle, achieving a win-win situation and long-term cooperation between the company and its users.
Industry data shows that for SaaS companies in North America that have been around for more than 5 years, over half of their annual revenue comes from renewals and additional purchases from existing customers.This verifies the significant contribution of CSM to the sustainable growth and profitability of enterprises.
