Customer success has evolved into a core revenue engine, requiring the same operational rigor and accountability as sales, marketing, and finance. For Chief Customer Officers, the challenge is not just delivering value to customers, but running CS as a scalable, predictable business function. This presentation focuses on the metrics that matter at the executive level - those that inform investment decisions, drive cross-functional alignment, and unlock sustainable growth. We will explore how to connect customer outcomes to financial performance through indicators such as net revenue retention, gross retention, customer lifetime value, and cost-to-serve, enabling CCOs to lead with data and demonstrate measurable business impact. Key takeaways: - How to position Customer Success as a revenue-generating function, not a cost center - The executive-level metrics that best reflect customer health and business performance - Ways to link Customer Success KPIs to board-level financial outcomes - Strategies to balance growth (expansion) with efficiency (cost-to-serve) - Practical approaches to building a metrics framework that drives accountability and decision-making
