Foundry
Real businesses, real numbers. No fluff.
A lot of people want to build tools and side projects, but before they start they want to know — does this actually make money? How much MRR does it pull? How long did it take to build? What tech stack did they use? Is it vibe-coded or fully custom? Foundry puts all of that in one place. You filter fast, move through businesses quickly, and within seconds you know if something is worth trying or not.

The Idea
Before building anything, most people want answers: How much does this tool make? How long did it take? What did they build it with? Is it vibe-coded or engineered from scratch? That kind of info is usually scattered across podcasts, Twitter threads, and interviews — and it takes forever to piece together.
Foundry is a structured, searchable database of 100+ real businesses — each one broken down into revenue, growth strategy, tech stack, time to build, and more. The goal is speed. You open it, you filter, and within seconds you know: this one makes $20K/mo, was built in 3 weeks with React and Firebase, and grew through SEO. Next.

How It Was Built
All the business data lives in a single curated text file — over 600KB of structured breakdowns. A custom regex-based parser runs client-side to extract every field: revenue, tech stack, growth tactics, founder background, and more. No external API calls for data. Everything loads from one static file, which keeps it fast.
- Custom data parser extracts structured fields from 600KB+ of raw text
