If you go on YouTube you can find a lot of vibe coders doing interviews where they drop a brief mention of their SaaS products. I think the main reason they are not well publicized is because they obviously have no moat. If I speak to a really big audience and tell them my SaaS which I vibe coded in 1 day is earning 10k/mo, then I'll have 10 competitors by tomorrow.

But if you want a "citation needed" name of someone shipping vibe coded apps and making money off it: on YouTube, Ed Yonge, or many of the guests on Starter Story.
