What they did
Used ChatGPT to make a one-page HTML site (runify.xyz) with a one-sentence pitch and rank images. Two options: pay $5 via a Stripe link to become an 'early adopter' (lifetime subscription once live) or join the email waitlist. All Reels traffic pointed there.
What happened
~2,000 waitlist signups and 90+ paid early adopters (~80 transactions, ~$400) in ~2 weeks; treated as clear validation to build.

In their words
The Superwall Podcast · Caleb Dean - I speedran an ai app from 0 to $100k exit in 26 days“we sent them to a website which I just like used ChatGPT to make like a I think it was still there, it's runify.xyz. And pretty much that was like a Stripe link with a landing page on it.”
“we had, I think it was in 2 weeks, posted less than 50 videos of this copied format, and we had like, in the end, 2,000 waitlist signups and I think it was like 90-plus people buy this like early adopter fee.”
