Validate Your Startup Idea in Minutes

Brain is an AI demand-validation agent for EU founders. Describe your idea, get a business canvas, run analyses, and test demand with landing pages.

We have not built this yet. This page is to find out whether enough people want it — if they do, you hear first.

Problem

You have a startup idea but no way to validate demand quickly. ChatGPT gives you answers but no persistence, workflow, or real demand signals.

Solution

Brain builds your business canvas from a shared knowledge base, runs analyses, publishes landing page tests, and reads demand signals from public data — all in one place.

How It Works

• Describe your idea — Brain creates a structured business canvas from your input.
• Run analyses — Get market, customer, and competitive insights automatically.
• Publish landing pages — Test demand with one-click landing page creation and built-in analytics.
• Read demand signals — Brain monitors public data for real interest in your idea. Planned
