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.

Tech stack

Everything you need to build it, get customers and get paid. Prices are public list prices, checked Oct 15, 2026.

1. Build

2. Get customers

  • X: post a short demo or before/after every day (free)
  • Reddit: answer questions in the subreddits your customers read; follow each subreddit’s self-promo rules (free)
  • Cold email: a short, personal note to 20 people a day who clearly have the problem
  • SEO: one helpful page per question your customers search for (free)

3. Make money

Model: Monthly subscription (SaaS)

Suggested price: $29 per customer per month

First 10 customers playbook

  1. Week 1: write down 30 people or businesses who clearly have the problem, and message 10 a day with a short demo.
  2. Offer the first 3 a free trial or a “founding” price in exchange for honest feedback and a testimonial.
  3. Post your demo and the first result on the channels above, every day for 2 weeks.
  4. 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 customers × $29 = $290/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: 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.
