IdeaRoast

IdeaRoast is an AI startup idea validation tool that critiques your business idea to find its fatal flaws before you build, using a panel of four AI examiners. Based on its homepage, the four agents cover market, tech, finance, and timing: they look for market gaps, competitor threats, weak unit economics, and timing risks, run live competitor data research, and return a structured verdict scored on a 0-to-10 scale with specific, actionable recommendations. Each analysis becomes a permanent, shareable case file, and a free preview is available before you pay. The product leans deliberately toward brutal honesty over encouragement, framing its job as telling you whether you'll end up with a product or a lesson. IdeaRoast is built for founders and entrepreneurs who want fast, structured, critical feedback, for teams or friends buying multiple analyses, and even for autonomous AI agents that can call it through a free API tier at /api/roast/free. Pricing is refreshingly concrete: a full analysis is a flat $1 with no account required and a verdict in about 60 seconds, with bundle discounts for teams and gifts. IdeaRoast is best when you want a cheap, fast gut-check that stress-tests an idea rather than affirming it. Because it is intentionally critical and quick, it is a screening step, not a substitute for deeper customer validation.

Founders use IdeaRoast to get a fast, critical AI verdict on a startup idea's flaws for $1 before building it.
