The problem

Claude is powerful.
Generic prompts waste it.

Most founders use Claude like a search engine. The difference between a useful output and a generic one is entirely in how you write the prompt.

😩
You get vague responses
"Write me a landing page" produces something no real customer would read. You need a prompt that thinks like a copywriter who knows your customer.
⏱
You rewrite the same prompt 5 times
You spend 20 minutes refining a prompt to get one useful paragraph. That's not a Claude problem — it's a prompt problem.
🤷
You don't know what to ask
The most valuable Claude use cases — architecture decisions, churn analysis, cap table clarity — never even occur to most founders.

The Honest Mirror
Most founders pitch their idea to friends who say "wow, great idea!" This prompt finds the people who'll tell you the truth.
I want you to stress-test my SaaS idea the way a second-time founder would — someone who's already lost money on a bad bet. My idea is [YOUR IDEA]. Don't be encouraging. Tell me: who specifically would pay for this (name a job title, company size, industry), who already solves this problem and how, the single most likely reason this fails in year one, and what evidence would change your mind. I want the version of this feedback I'd only get after paying a consultant $500.
💡 If you can't answer "who already does this" before reading the response, you haven't researched enough yet. The other 49 prompts are this specific.
Is this for you?

FAQ

Common
questions.

What exactly do I get?
A PDF with 50 prompts across 6 categories — each with the full prompt text, a description of what it does, and a pro tip on how to get the most from it. Plus a Notion setup guide as a bonus.
Do I need a paid Claude account?
The free Claude.ai plan works for most prompts. A Claude Pro subscription ($20/month) gives you faster responses and higher usage limits — recommended if you're using it daily.
Can I use these with ChatGPT or Gemini too?
Yes. The prompts are written for Claude but work well with any capable LLM. Claude tends to produce the best results for the reasoning-heavy prompts in the Validate and Finance sections.
Will this work for my specific industry?
Every prompt uses [BRACKET] placeholders — you replace them with your specific product, industry, and ICP. That's what makes them useful rather than generic.
Is there a refund policy?
If you genuinely feel the pack didn't deliver value, email us within 7 days of purchase for a full refund. No questions asked.
