What is Customer Success? The 2026 Definition
Customer Success has evolved dramatically since 2004. Learn why 2026 demands a new definition and how data-driven, AI-augmented CS delivers 7-10% higher NRR.
Customer Success is no longer just a department—it is a business strategy that directly impacts revenue, retention, and growth. In 2026, with AI capabilities and data-driven insights at our fingertips, the definition of CS has evolved far beyond its origins.
The Evolution of Customer Success
2004 marked the birth of Customer Success when Salesforce created the first dedicated CS team. The 2010s saw the SaaS explosion that made CS essential for subscription businesses. By 2020, we entered the era of Digital CS and AI transformation. Now in 2026, we are witnessing proactive, data-driven, AI-augmented Customer Success.
CS vs Account Management vs Support
Understanding the difference between these functions is crucial:
| Function | Focus | Approach | Key Metrics |
|---|---|---|---|
| Customer Success | Outcomes | Proactive | NRR, Health Score |
| Account Management | Revenue | Relationship | ARR, Expansion |
| Support | Issues | Reactive | CSAT, Resolution Time |
Each function serves a purpose, but only CS ensures long-term customer value.
