Founder: test your business idea with 11 free Claude skills
A board that reviews your idea, 100 AI buyers, a pricing expert, a CFO and a marketing director. You get a business plan with a verdict: Profitable or Not yet.
Checked on 11 Oct 2026. Tools change fast, so the official page always wins if it says something different.
What it does
- Board of directors: three reviewers using ideas from $100M Offers (Alex Hormozi), Zero to One (Peter Thiel) and Walter Isaacson's Steve Jobs. They score your idea and vote.
- Consumer panel: 100 simulated buyers built from your target customer. Who buys, who doesn't, and why.
- Pricing strategist: the price range people accept, checked against competitors.
- CFO: profit per sale, break-even per day, year one month by month, cash you need.
- Marketing director: positioning, a dated 30-day launch campaign and ten hooks.
- Business plan: everything in one file with a verdict worked out from the numbers.
What you need first
The GitHub page, explained
Free tools like this live on GitHub. Open github.com/Jakeschincariol/founder-skill and this is what you'll see at the top:

- Star (290+): how many people saved it. More stars means more people trust it. Clicking it is optional and needs a free GitHub account.
- Green Code button: the download button. You only need it if a step below tells you to.
- About: one line on what it does, so you know you're on the right page.
Scroll down the GitHub page to README: that's the creator's full manual. This page is the simple version.
Step by step
Quick version: use one skill in a normal Claude chat
Open the board skill, copy the whole file, paste it at the top of a new Claude chat, then describe your idea.
Tip: In a normal chat you lose the sub-agents and the number tools, but the method works. Do the same with founder-consumer, founder-pricing and the others.
Full version: install Claude Code
All 11 skills, the 100-buyer panel and the CFO tools need Claude Code (paid Claude plan). Run this in Terminal (Mac) or PowerShell (Windows):
curl -fsSL https://claude.ai/install.sh | bash
irm https://claude.ai/install.ps1 | iex
Add the Founder skills
Start Claude Code in a new folder for your idea, then add the plugin:
/plugin marketplace add Jakeschincariol/founder-skill
/plugin install founder-skill@founder-skill
Run them in order
Start with the board, then the buyers. Each skill reads what the last one wrote.
/founder-skill:founder-board I want to open a matcha café in Toronto, iced lattes at $6.50, for office workers who buy coffee every day.
The order that works
Each one reads the last one's notes.
board → competitors → consumer → pricing → offer
cfo → marketing → brand → ops → launch → plan

The catch
- The 100 buyers are simulated, not real customers. AI tends to be too nice, so treat their "yes" as a best case and test with real people before you spend big.
- The numbers are only as good as what you give it. Get real quotes for rent, stock and staff.
- It isn't those people. The board uses short summaries of ideas from their books. It doesn't speak for them and isn't connected to them.
- Not financial, legal or tax advice. Check permits, tax and contracts with a professional.
- The full version needs Claude Code, and running 100 buyers uses a lot of your plan's limits.
