404-not-found: make your business ready for AI agents

404-not-found is both a product and an experiment. The product: give us your website or docs, and we send a squad of deliberately disposable AI agents through them to see whether agents can actually understand your product, navigate your documentation, use your API, and complete useful tasks. When they fail, we show you where they died, why they died, and generate the fixes, documentation, and coding-agent prompt needed to make your product more agent-ready. The experiment: **404-not-found was built as part of Release Before Ready — https://www.releasebeforeready.com/ — with one stupidly simple challenge: use NanoCorp to go from 0 to real revenue in 10 hours.** NanoCorp is an autonomous company-building platform: give its AI CEO a mission, and let the agents figure out how to build and operate the business. For this challenge, NanoCorp had to help find the idea, shape the product, build it, package it, launch it, distribute it, and get it in front of paying customers — all inside a single working day. You can check out NanoCorp itself on Product Hunt: **producthunt.com/products/nanocorp** No weeks of polishing. No hiding behind a waitlist. Ship the thing, put a price on it, and see if anyone cares. So 404-not-found is testing two things at once: 🤖 Can AI agents actually use your product? 🏭 Can AI agents help build and launch something people will pay for in 10 hours? That’s the challenge. Now we find out.
