Our average subscription revenue for net new DOS Subscription Clients signed in the year ended December 31, 2023 (new 2023 DOS Subscription Clients), was toward the low end of the average expected range of $500,000 to $1,500,000, driven primarily by greater demand of stand-alone DOS module components, such as Healthcare.AI, which resulted in subscription revenue that is significantly lower than subscription revenue derived from a contract that includes access to all of the DOS platform components and analytic applications.
Our average ARR and non-recurring revenue for net new Platform Clients signed in the year ended December 31, 2024 (new 2024 Platform Clients), was toward the low end of the historical average expected range of $400,000 to $1,000,000, driven primarily by Platform module components, such as Healthcare.AI, that result in ARR that is significantly lower than ARR derived from a contract that includes access to all of the Platform components and analytic applications.
