AI-powered startup validation

Your startup idea has blind spots.
Find them before investors do.

Crucibl is an AI agent that debates your startup idea from both sides, researches the market autonomously, and tells you exactly where you're most likely to fail — and what to do about it.

How it works

Four phases. One verdict.

Step 01
Describe your idea

Paste your startup idea in plain English. Crucibl's probing agent asks pointed questions to surface your hidden assumptions.

Step 02
Autonomous research

AI searches the web, Reddit, Hacker News, app stores, and competitor landscapes for real evidence.

Step 03
Bull vs. Bear debate

Two adversarial agents argue the strongest case for and against your idea, grounded in research.

Step 04
Validation brief

A synthesis agent reconciles the debate into a balanced, evidence-cited brief with risk scores and next steps.

Who it's for

Built for people who'd rather know now.

Solo founders

Crucibl won't say it's great. It'll find the Reddit thread where someone tried your idea in 2019.

Get the honest feedback you can't get from friends and family. Crucibl stress-tests your assumptions with real market evidence before you write a single line of code.

Startup teams

Spend 10 minutes with Crucibl before committing 6 months to building.

Align your team around validated assumptions. Surface blind spots in your pitch before the board meeting, not during it.
