In their words
I Built A Micro-Version Of A $1B SaaS. Now I Make $50K/Month
Pat WallsOkay, cool. So, you've had some success under your belt, but this idea seems like it could be really big. How did you get the idea to build an AI coding app?
DavidSo, it was summer 2025, and we saw no-code and AI app builders explode. Just a few examples: Base44 hit 3 million ARR in 6 months, then Lovable went to 1 million ARR in a week from launch and is now valued at 6 billion. We figured owning even 1% of the market would be life-changing for us. So, the plan was really simple: find one common pain point and triple down on it.
Pat WallsOkay, cool. I love that you mentioned find one common pain point, triple down on it. If you can even own 1% of this massive market, which is AI coding tools, it could be life-changing. We're going to talk more about that, but before we do, let's talk about how you build this thing. How do you go about building an AI coding tool? It seems really complicated.
David… small, just us and one developer, and the first version was pretty rough. It broke a lot, but we shipped it anyway, so instead of waiting for it to be perfect, we just focused on getting it in front of people. Overall, I'd say the first two months were the toughest, but things started to improve pretty fast. So, by month three, we had a working product that we're confident with. By month four, we moved past just catching up with our competitors.
DavidBy months five and six, we were already shipping features that even our competitors didn't have yet. We also kept a close eye on other players in the space, looking at what worked for them, what didn't, so we could move faster and avoid making the same mistakes that they did.
Pat WallsOkay, cool. So, you built this AI coding tool, even if you had a developer or two, that's still amazing. This is what's possible building products with AI. So, on that note, I'm curious, like, what's the tech stack behind this?
