Ask Rosamel something hard.
Roast my idea: a no-show deposit app for independent dog groomers, $29 a month. I interviewed 12 groomers and everyone said it is great. Give me a full validation and a go or kill call.
CLAUDE · AS ROSAMEL, STARTUP IDEA VALIDATOR

What you're actually buying
Rosamel runs business idea validation before you spend a month building. She roasts your idea with evidence, not opinion, finds the riskiest assumption, writes Mom Test interview scripts, grades your problem evidence from compliments up to payments, sizes the market bottom-up, fills a 9-block Lean Canvas and designs smoke tests such as a waitlist page, fake door, concierge or pre-sale. You finish with a go, pivot or kill scorecard and a 14-day plan.
For founders, side-project builders and corporate innovators who want the honest answer early. Rosamel never invents market sizes or survey results; missing figures are marked MARKET DATA NEEDED with a source to check, and you set every pass or fail line before a test runs. Thomas, the AI Business Plan Generator, the Startup Bundle, the Startup Templates Pack and the Founder Stack Bundle help once you decide to build. Rosamel decides whether to build at all.
An honest go, pivot or kill call on your business idea, backed by customer evidence, not compliments.
Compatible with: Claude, Claude Code, ChatGPT, Gemini and Copilot. Install once as a Skill in Claude or paste it as instructions in any other AI chat.
- Will it just tell me my idea is great? No - Roast mode lists every weak spot with the evidence behind it and the cheapest test that could prove it wrong.
- Does it make up market size numbers? No - it sizes bottom-up from customer counts and price, and marks any missing figure with where to find it.
- Can it write my customer interview questions? Yes - it writes Mom Test scripts about past behaviour, plus a note sheet and a commitment ask to end each call.
- Who decides if a test passed? You do - you set the pass and fail thresholds before the test starts, so results cannot be reinterpreted later.

Вопросы об этом товаре
What does Rosamel - Startup Idea Validator do?+
Rosamel validates a business idea before you build it. She restates it, roasts it with evidence, maps assumptions and names the riskiest one, grades your problem evidence, writes Mom Test interview scripts, sizes the market bottom-up, fills a Lean Canvas, designs a smoke test such as a waitlist, fake door, concierge or pre-sale, and ends with a scored go, pivot or kill call.
How is Rosamel different from Thomas, the Business Plan Generator or the startup bundles?+
Thomas - Business Consultant structures problems and business cases for an existing company. The AI Business Plan Generator writes the plan for funders once the idea is decided. The Startup Bundle, Startup Templates Pack and Founder Stack Bundle produce documents or run departments. Rosamel works before all of them and answers one question: is there enough evidence that people want this to justify building it.
Is the roast just harsh for the sake of it?+
No. Every hit cites its basis: something in your notes, a missing piece of evidence or a well-known pattern, plus the cheapest test that could prove Rosamel wrong. She criticizes the idea, never you. You can pick Gentle, Standard or Brutal intensity, and Brutal follows the same evidence rules, just without cushioning.
Can it tell me if I have product market fit?+
Once you have users, Rosamel reads a Sean Ellis survey: the share answering very disappointed if they could no longer use your product, with 40 percent as the commonly used leading indicator and small samples treated as directional. Before a product exists, she grades evidence on a ladder from opinions up to payments instead.
