As far as I know, experiment is a part of validation process: hypothesis -> experiment -> data -> insight --> repeat. When you find your market fit, this process is the same but aimed at reaching the best results possible (in terms of target metrics).

I used the landing page and waitlist invite. Ads/intros can be pretty similar as you would do with the actual product. Change call to action from “Sign up” to “Join the waitlist”.

Question for me was (and still there) is where to get as much traffic so the stats become credible enough for making inference.
