In 30 days: your runway and true weekly cost counted, 20 problem interviews scored on one sheet, a priced offer in front of the best of them, and a count of who paid a deposit. A go, change or kill verdict that costs you a month, not a year and your savings.

The Problem

Most new founders build first and ask last. Building feels like progress. Asking feels like risk, because the answer can be no.

The public post-mortems point the same way. In CB Insights' 2014 study of 101 failed startups, mostly tech, the top 2 reasons were no market need and running out of cash. This book tests the first before you build, and measures the second before you start.

Interest is not payment. Twenty people saying yes is not twenty people buying.

What's in the Book


A Sample: What a Guarantee Really Costs

A hypothetical deck stain business charges $1,200 a job. Delivery costs $500, so gross profit is $700. A full refund guarantee loses the $1,200 and the $500 already spent: $1,700 a claim. If 1 buyer in 10 claims, that is $170 per job sold, about 24% of gross profit. A "we redo it if you followed the care sheet" guarantee costs $500 a claim, $50 per job, about 7%. Every number is a round hypothetical. The book shows you how to run it on yours.


Questions

Does it promise me customers? No. It gives you a verdict you can trust, from your own counts. Nobody who has not met your market can promise you a customer count.

Does it tell me what score or how many deposits means go? No. You write your own lines before you see the count, so the line cannot move to fit the answer.

Is it legal or tax advice? No. Part 10 lists the 5 questions to bring to an accountant and an attorney. Fees and filing facts sit in a dated appendix.

What happens after a go? The First 100 Customers Guide picks up: outreach, first-customer pricing, referrals and which channels to open, in order.


Who This Is For

Someone with a business idea for a local service or small service business who has not sold anything yet, or has sold only to friends, and wants to find out cheaply whether strangers will pay before quitting a job or spending savings.
