Who it’s for

Anyone who wants to start or grow a small online business, including people who can’t code.

Adapt it to your industry

  • Coach: an app or tool that helps clients between sessions
  • Shop: a tool that solves one annoying problem for your customers
  • Freelancer: package your best service into a self-serve product

Step by step

  1. Write down one problem a specific group of people pays to solve (for example “gym owners losing members”).
  2. Open ChatGPT, Claude or Grok and paste the prompt below to sharpen the idea and list what the first version must do.
  3. Build a simple first version with a no-code builder such as Lovable, Bolt or Bubble, or with Cursor if you code.
  4. Create a Stripe account and a Payment Link so people can pay from day one.
  5. Make a one-page website that explains the problem, the fix and the price.
  6. Show it to 10 people from your target group and change what confuses them.
  7. Launch where those people already gather, then ask every new user for feedback.

Ready-to-copy prompt

Plan a 90-minute retrospective for 8 people using cards from the deck. Give timings and which card to use at each step.

How to make money from it

Pricing idea: Start with one simple monthly plan (for example $9–49 a month for consumers, $49–299 for businesses) and a free trial or free first use.

Finding your first 10 customers

  • Write to 30 people who clearly have the problem (forums, LinkedIn, your contacts) and offer early access.
  • Give the first users a lower “founding” price in exchange for feedback.
  • Post your build progress publicly every week.

Worth knowing

For non-developers, an installable MCP beats an API.
