Journey · Non-technical founder · 5 full days · Level 1 to Level 3

What you get out of the week

On Monday you arrive with an idea. On Friday you know whether it's worth building. You'll have a first version that three real people have tried, what they did with it, what it would cost to run, and a decision: go, change or stop. In between you use AI where it saves you time, and check it every time it answers.

The idea stays the same all week. Each day asks a bit more of it:

  • Level 1: you can explain it and you've seen what already exists.
  • Level 2: a real user can try a first version without you explaining it.
  • Level 3: you can decide, with numbers, whether it deserves more of your time and money.

Who this is for

You have an idea for a product or service, and you don't write code. You have used a chatbot. You have never opened a terminal, and this week you won't need to.

You bring one idea, and three people who have the problem it solves. They agree to a 20-minute call on Tuesday and a 25-minute video test on Thursday. They should be people who might pay, not friends being kind.

The method behind every day

Monday to Thursday, each day is one trip round the four quadrants from T01-L01 · From Idea to Working Result: The Four-Quadrant Method. The quadrants form a grid of four boxes: two about the problem, two about the solution. Friday is for the decision.

The problemThe solution
DefineStructure itChoose tools
Explore and testUnderstand itBuild it
  • Structure it: say in one sentence who has the problem, what they do about it today, and how you'll know your idea helps.
  • Understand it: find out what already exists and what your users really do. When that changes the problem, go back to Structure it. This back-and-forth is where most founders save months.
  • Choose tools: start with the simplest option and only move up when it fails. First, something that already exists. Then a small change to it, then a template, a form or a spreadsheet. Last, a built app with AI in one part only.
  • Build it: make the smallest version a user can try, test it, and fix what breaks.

How Monday to Thursday run

TimeQuadrantWhat happens
09:00–10:30Structure itA 20-minute demo, then you write today's problem sentence.
10:45–12:15Understand itYou look at what already exists: competitors, workarounds, what your users told you.
13:15–15:15Choose toolsYou try options and pick the simplest one that works. Then you start building.
15:30–17:00Build itYou finish today's result. Your partner tries it, and you write the exit check.

Breaks: 15 minutes mid-morning, an hour for lunch and 15 minutes mid-afternoon. There's no homework. All reading happens in the room: the trainer points you to the parts of each book you need that day.

You work in pairs, each on your own idea. Your partner plays your customer and checks your work, and you do the same for them. The course runs with up to 12 people per trainer.

The five-line exit check closes every day, Friday included. It's the only paperwork:

  • Problem: today's final Structure it sentence.
  • What exploring changed: what you learned in Understand it, and how it changed the problem.
  • Choice: the tool or method you picked, and why it's the simplest that works.
  • Result: what you built, and whether it worked when someone tried it.
  • Next step: the one thing you'd change on the next trip round.

Monday: the problem, and for whom

Most ideas fail because they solve a problem nobody has badly enough. Today you pin the problem down before you think about the product.

QuadrantWhat you doRead
Structure itWrite one sentence: who has the problem, what it costs them today, and what would count as better. Add the test you'd accept on Thursday and what each result means, for example: "three of three users finish without help: go; two: change; fewer: stop".T17-L02 · Frame a Problem Your Team Agrees On
Understand itSort what you know by colour (see below). Meet the four facts about AI assistants (see below). Rewrite your sentence.T12-L01 · Decide What You May Paste Into AI at Work

Build itWrite the questions for Tuesday's calls with an assistant's help. Ask about what users do today, not whether they like your idea. Check that no question gives the answer away.T02-L01 · Get Answers You Can Use from a Chatbot

The three colours:

  • Green: already public, like a competitor's website or published prices. Any tool.
  • Yellow: internal but not sensitive, like your notes with no names in them. Only tools on a business plan whose terms say they don't train on your data.
  • Red: your users' names and details, your own prices and contracts, and anything confidential. No online AI tool.

The four facts about AI assistants:

  • It writes what sounds right.
  • It starts every chat from zero.
  • It sounds just as sure when it's wrong.
  • What you type goes to the provider.

What goes wrong today: the assistant tells you your idea is great. It will tell everyone that. The only opinions that count this week come from your three users.

Tools: a chat assistant, for example ChatGPT or Claude.

Tuesday: what already exists, and what users really do

Someone has probably tried your idea, or your users have a workaround they're used to. Today you find out both.

Mark each claim as supported, unsupported or not found in your notes.T04-L01 · Ask Your Own Documents and Check Every Citation

What goes wrong today: the research tool names a competitor that closed last year, or a price it made up. You only catch it because you opened the page.

Tools: Perplexity to map the market, and a notebook tool on a business plan for your notes, for example Gemini notebooks with a work account.

Wednesday: the smallest version someone could try

Today you build the first version: the smallest thing a user could try on Thursday without you explaining it.

What goes wrong today: the first version grows. Every feature feels necessary, and by 15:00 nothing works. Cut back to the one thing Monday's test measures.

Thursday: real users try it

Today your three users try the first version while you watch, and you measure it against the test you wrote on Monday. This is a short user test, not a full pilot: from T17-L04 · Run a Pilot with Real Users and Real Data you borrow only its one-page plan.

What goes wrong today: users do something you never planned, and skip the feature you're proudest of. That's the most valuable thing you'll learn all week.

Friday: go, change or stop

Today you decide, with the numbers from Thursday in front of you, not with your hopes.

"Stop" is a good result. It costs you a week instead of a year.

How you pass

There are no points. You pass when all five of these are true:

  1. It runs. You show your first version live on Friday.
  2. Three real users tried it, and you wrote down what they did.
  3. You decided against a test you set before the test. Monday's test, Thursday's results, and go, change or stop.
  4. You know what it would cost per month, with 10 and 100 users.
  5. No red data went into an online AI tool, and your five exit checks are complete.

What you take home: your first version, your notes from six conversations, a monthly cost estimate, a one-page decision and a plan for the next 30 days.

Before Monday

  • Line up three people who have the problem, and book the times: a 20-minute call on Tuesday late morning and a 25-minute video test on Thursday late morning.
  • Accounts: a chat assistant. The course provides trial accounts for the build tools.
  • A laptop you may install software on: a Mac or a recent Windows PC.
  • Nothing to read in advance.

What this week leaves out

  • Raising money and pitch decks.
  • Company law and contracts.
  • Building the full product.
  • Hiring developers.

Further reading and tools

All the books in this journey are listed below the course, in the order you meet them.

Rule to remember: talk to users before you build, build the smallest thing they can try, and let what they do decide.
