We focus our direct selling efforts on expanding our customers’ use of our platform, which includes companies that are exhibiting significant growth. We engage with and support these customers with our field sales representatives, account managers, and technical account managers who focus on customer satisfaction and drive expansion of their usage of our platform and products. These teams work with technical and business leaders to help our customers’ end users receive the best possible digital experience, while also lowering our customers’ total cost of ownership. These direct selling efforts are reflected by the revenue generated by our enterprise customers. Our Last-Twelve Months Net Retention Rate (“LTM NRR”) metric also measures the revenue growth from existing customers attributable to increased usage of our platform and features, and purchase of additional products and services. For additional details on our key metrics, refer to the “Key Business Metrics” section.

We calculate the Compound Annual Growth Rate (“CAGR”), which represents the rate of revenue return of our revenue cohorts, over a five year history from when they were first customers
