The Rise of the CSM Platform: How Customer Success Management Became the Engine of Modern SaaS

In the early days of software-as-a-service (SaaS), the sale was the finish line. Once a company convinced a customer to sign a contract, pop the champagne, the revenue was locked in, and the primary focus shifted to acquiring the next logo.
