Business Idea Validation & Value Proposition
Tests whether people will pay for what you offer, defines the value proposition, and checks the employment contract.
What Grace brought · her 2025 client list
“I’ll write copy for anyone who asks. Last year I had nine clients.”
What the prompt returned
Three of the nine were independent physical therapy and chiropractic clinics: 54% of her revenue and the fewest revisions. Her contract allows outside work that she discloses, outside her employer’s industry.
The analysis · Nine clients in seven industries earned her $30 an hour
A value proposition is the specific result a client pays for, and the reason to buy it from you rather than someone else. Customer discovery, Steve Blank’s method, tests an idea with real buyers before building it: only payments and commitments count as evidence.
- $9,900 from 3 clinics: a third of her clients produced more than half her revenue, because clinics bought whole websites and asked for fewer changes.
- A clause she had never read: her employment contract requires written disclosure of outside work and bars clients in her employer’s industry. She disclosed in May; clinics are outside it.
- One client type: every later prompt is built for independent clinics, not for anyone who asks.
Takeaway: choose the client type your record shows pays best, and check the employment contract before the first client.
