The clock from signup to the moment a user gets the first real benefit your product promised, where TTV (Time to Value) is measured in seconds, minutes, or full sessions.
Canva's growth team has spoken publicly about treating 'time to first published design' as a load-bearing metric, with the target measured in single-digit minutes. Templates, drag-and-drop, and one-click resize all exist to shorten that clock, which is one reason Canva crossed 100M monthly active users in 2022 with almost no enterprise sales motion.
