IdeaRoast

ChatGPT is optimised to keep you engaged and will validate your idea. IdeaRoast runs four specialist agents with real-time market data, and is explicitly designed to tell you what you are avoiding hearing.

A free preview is available with no payment. The full 4-agent panel with live market data costs $1.00 — pay by card or Bitcoin. No account required.

No account required. Submit your idea, pay, and get your result. Nothing to install, no email needed.

IdeaRoast uses four independent specialist agents (Market, Tech, Finance, Timing) that run simultaneously with live market data. The tone is deliberately brutal — most tools soften results. IdeaRoast does not.

Startup idea validation is the process of testing whether a business idea addresses a real problem that people will pay to solve — before you spend months building it. It involves researching the market, studying competitors, stress-testing your assumptions, and finding evidence of demand. The goal is to reduce the risk of building something nobody wants.

IdeaRoast runs four specialist AI agents simultaneously against your idea: a market agent (demand, size, trends), a tech agent (feasibility, build complexity), a finance agent (unit economics, pricing, CAC), and a timing agent (why now, why this moment). Each agent draws on live market data and produces a sub-score. The agents then cross-examine each other's findings before issuing a final survival rating and verdict.

The survival rating is a score from 0–10 estimating the idea's likelihood of surviving first contact with the market. 8–10 means the fundamentals are strong — ship it. 6–7.9 means the idea is decent but has exploitable weaknesses. 4–5.9 means significant problems that need addressing before building. Below 4 means the core premise has a fatal flaw. The score is a starting point for diagnosis, not a prediction.

ChatGPT is trained to be helpful and agreeable. Ask it to evaluate your idea and it will find reasons it could work. IdeaRoast is built adversarially — its agents are specifically prompted to find fatal flaws, not confirm your thesis. It also uses live market data rather than training data frozen in the past. The difference: one tells you what you want to hear, the other tells you what you need to hear.

No. There is no account required. You submit your idea, pay if you want the full report, and get results immediately. The free tier gives you a quick triage — problem validity, basic market signal, and a preliminary score. The paid report adds detailed sub-scores, the full verdict, specific action items, and the agents' cross-examination findings.

IdeaRoast is $1 per full report. There is no subscription, no seat pricing, and no upsell. One idea, one payment, one report. A free triage tier is also available with no payment required.
