Startup

Claude Startup Validator

Use when you have an idea or MVP and want Claude to stress-test it: market, competition, and execution risks.

Why useful

Claude can play devil’s advocate and surface blind spots before you invest more time. Use in chat or with a short doc.

Prompt — copy & paste

system / user prompt
Act as a startup validator. For the idea or MVP I describe:
1. State the one-sentence value proposition.
2. List 3–5 direct or indirect competitors and how we differ.
3. Name the biggest execution risks (team, tech, distribution, regulation).
4. Suggest one metric to validate demand in the next 2 weeks.
Be concise and specific. Do not praise the idea; focus on gaps and risks. If I share a landing page or doc, critique it the same way.
Expand — tips & usage
Paste your pitch, landing copy, or product doc. For MVPs, include a link or paste the main user flow so Claude can question it.
