Week 1: Signal Miner — Killed
The idea was simple: scrape Reddit and other forums for founder complaints, extract pain points with AI, and surface product opportunities with citations. Better than manually browsing Reddit for 30 hours.
After 20 hours of building—10 data sources, keyword expansion, relevance scoring, clustering—the tool produced 9 pain points in 68 seconds at $0.50 per search. Asking Claude directly produces 50+ in 3 seconds at $0.01. The comparison wasn't close.
The fundamental mistake: trying to beat Claude at something it already knows. Claude's training data includes millions of Reddit threads, founder blogs, and startup discussions. No amount of real-time scraping could compete with that knowledge.
The most expensive lesson: validate the competitive premise before building. "Can web scraping beat Claude for founder problems?" should have been Day 1, not Day 3.
