"It won't scale." "The code quality will be terrible." "No serious customer would pay for that."
Skeptical statements like these have dominated the conversation ever since Andrej Karpathy introduced the concept of "vibe coding" — when you build apps primarily through prompting AI models to write the code.
But a growing cohort of entrepreneurs has ignored the critics to make real products that are making real money.
This post is about these products. We'll cover the basic details of each app but we'll also go deeper, digging into their revenue numbers, the backgrounds of their founders, the AI tools used to create them, and more.
Let's start with an at-a-glance look at each app and its performance.
