It took me 14 days to build CodeGuide.dev and within 90 days we've gone from 0 to 42k per month. This is CJ, a longtime member of Starter Story and a few weeks ago he sent me a DM that blew me away. In just 49 days he took his app from 0 to $17,000 a month without spending a single dollar on marketing. But what's even crazier is he didn't even build the product until he knew it was validated. So I didn't build any product, I didn't have anything, I just had a glimpse of what a product can look like in a landing page. And people were signing up from left and right and that was the moment when I decided, okay, now I need to take this and create like a proper tool that solves this problem. Now I know what you're thinking, he's probably got a huge audience, but that's actually not true. It all started when CJ set out to build 12 startups in 12 months, which ultimately led him to an idea that would change his life forever. I brought CJ onto the channel to tell his story and he shared everything, including a full breakdown of the tweet that broke his startup, how he got thousands of signups before writing any code, and the unexpected marketing strategy that's grown his business to over 500,000 in ARR. If you're building an AI, this is a must watch because this is what is actually working right now. So let's get into it. I'm Pat Walls and this is Starter Story.
