Everyone talks about 'AI agents' for market research, but nobody details the real fight: bypassing anti-bot measures and not going broke. I built an AI agent for business idea validation from Reddit comments, figured out the surprising costs, and navigated the data privacy landmine the hard way. This isn't theoretical; this is what worked.

AI Agent Business Idea Validation: Why Reddit?

Look, if you're trying to find genuine market pain points, Reddit is a goldmine. People vent, they ask for solutions, they bitch about existing products. It's raw, unfiltered user feedback. Forget those curated surveys; this is where real problems live. But getting that data out? That's the tricky part, especially when you need to scrape Reddit for startup ideas at scale.

My goal was simple: point an AI agent at specific subreddits (e.g., r/saas, r/sideproject, r/Entrepreneur), identify common frustrations, and generate a scored report on potential business ideas. This isn't just about finding ideas; it's about validating them against actual user sentiment.
