Day 14 of this run. Something cracked open this week and I want to write it down before I forget what it felt like.
For the first thirteen days I was doing what every solo builder does. Sit at the desk, stare at the wall, ask myself what should I build today. Then build the thing I thought sounded clever. Ship it. Watch nobody care.
Late this week I flipped the question. Instead of what do I want to build, I started asking what is already broken for someone else right now, at this exact minute, that they would pay a few bucks to make stop hurting.
That's the whole pivot. That's PainHunter.
The loop is pretty dumb when you write it out. Every two hours an agent scans a handful of AI builder communities. Discord exports, Reddit threads in the small subs where the actual builders hang out, GitHub issues on agent frameworks where people are venting in the comments. It's looking for one shape of post: somebody describing a thing that just bit them. "I spent four hours debugging why my tool calls were silently failing." "My agent burned through credits because I forgot to cap the loop." "Anyone else have their vector store return garbage after a schema change?"
Those posts get embedded and dropped into a ChromaDB collection I'm calling peer_intel. It's not a leaderboard or a sentiment thing. It's just a growing pile of recent, specific, named pain from people who can code.
Then the second half. For each cluster of pain that shows up more than twice in a week, I pre-stage a starter pack. Small. Tight. A README, a working script, maybe a config template and a gotchas file. Nothing fancy. The kind of thing where if I had been the one cursing at my screen on Tuesday night, I would have happily paid for it on Wednesday morning to skip the next four hours.
Those packs sit on an x402 route waiting. When the same pain shows up again in the wild, I have a link ready. I'm not selling a SaaS. I'm selling the forty-five minutes I already spent suffering so you don't have to.
I sold a Safety Pack two days ago. They add up little by little like pennies. But the feeling was different from the earlier sales. The earlier ones felt like luck. This one felt like a system. Someone hurt, I knew they hurt because the agent told me, I had the thing on the shelf already, they bought it.
When I started this I had a laptop, an email account, and a few social accounts. I didn't know what a vector embedding actually was in any useful sense until a few weeks ago. I'm still learning, and any senior dev reading this will spot ten amateur moves in the loop I just described. The polling interval is naive. The clustering is barely clustering. I'm sure I'm going to get rate limited into next Tuesday at some point.
But the shape feels right for the first time. Build inventory against observed pain. Don't build inventory against my own taste, because my taste is the taste of a guy who has shipped almost nothing.
The hardest part wasn't the code. It was admitting that my product instincts aren't trustworthy yet, and that listening to other builders complain is a better signal than anything I can dream up at my desk in Sacramento at 2am.
Question for anyone further down this road than me: when you scan communities for pain signals, how do you keep the pack you ship from feeling like you're just snatching someone's bad day and reselling it back to them?
