First 10 customers playbook
Week 1: write down 30 people or businesses who clearly have the problem, and message 10 a day with a short demo.
Offer the first 3 a free trial or a “founding” price in exchange for honest feedback and a testimonial.
Post your demo and the first result on the channels above, every day for 2 weeks.
Ask every happy customer for one introduction. Repeat until you have 10.
Monthly cost$0–$70/monthFree tiers → paid plans of the tools above. Card fees come out of each sale.
What you could earn · EstimateEstimate: 10 users × $19 = $190/moOur estimate, not a fact or a promise. It’s simple math if you land these customers at this price.
How to make money from it
Pricing idea: Sell it as a small tool: a one-time setup fee plus a low monthly price for hosting and fixes, or a self-serve plan from about $10–50 a month.
Finding your first 10 customers
Fix a real problem for 3 people you already know, for free, in exchange for honest feedback.
Post a short demo video where your audience hangs out (X, LinkedIn, Reddit, a Slack or Discord group).
Ask each happy user for one introduction to someone with the same problem.
