TTFHW is not the most common acronym you’ll hear in the tech and product domain. Even though it’s not extremely common, it can be argued that it is one of the most important acronyms for companies trying to scoop up and deliver value to new users.

TTFHW, or Time To First Hello World, is likely something you’ve already thought about. Many product-led enthusiasts refer to it as the customers’ “aha!” moment. This is the moment when a customer first derives value from your platform. Something many programming languages and programmer tools refer to as a “Hello World” moment. It’s a make-or-break milestone and one that you obviously want every customer to experience. TTFHW is simply the amount of time it takes to get to that “aha!” moment.
