. We may treat separate subsidiaries, segments, divisions, or business units of a single organization that use our platform as unique customers where they have distinct account identifiers. In cases where charges are identified through a reseller partner rather than on an end-customer basis, we would count the reseller as a single customer in our customer count. Our customer groupings may be impacted by changes to our customers’ business, including any impact from acquisition activities, internal business reorganizations leading to operational and decision-making changes, and corporate structure changes such as subsidiary consolidation and reorganization that may arise in the future.

Our enterprise customer count is defined as customers with annualized current quarter revenue in excess of $100,000. This is calculated by taking the revenue we recognized for each customer in the current quarter and multiplying it by four. As of December 31, 2024, we had 596 of such enterprise customers which generated 93% of the total annualized current quarter revenue for our total customers for the period ended December 31, 2024.
