ChatGPT Prompt for Business Model Canvas: 10 Block Prompts

A good ChatGPT prompt for business model canvas work should fill the nine blocks from your own notes and label every line as evidence or assumption. That turns the canvas from a nice diagram into a test plan: you see which parts of the business you know and which you are guessing. Below are 10 copy-paste prompts for filling the canvas, checking the numbers, and testing the weak spots, plus a flagship prompt that does the whole job from interview notes.

The Business Model Canvas was created by Alexander Osterwalder and is published by Strategyzer. Its nine blocks are Customer Segments, Value Propositions, Channels, Customer Relationships, Revenue Streams, Key Resources, Key Activities, Key Partnerships, and Cost Structure. The prompts below follow that order. This is not financial or legal advice.

Prompts for filling the canvas

1. Customer segments

From these interview notes: [notes], list the customer segments for [business]. For each, say how many interviewees fit it and what problem they described.

2. Value propositions

Match each customer segment: [segments] with a value proposition for [business] that answers a problem from [notes]. Quote the problem as the customer said it.

3. Channels and relationships

Here are channels we tried and their results: [channels]. Fill the Channels and Customer Relationships blocks, keeping what worked, dropping what did not, and tagging untested ideas as assumptions.

4. Back stage blocks

Fill Key Resources, Key Activities, and Key Partnerships for [business] from [resources and partners]. Flag any activity nobody on the team can do yet.

5. Evidence or assumption

Here is my draft canvas: [canvas]. Tag every line as evidence (with its source) or assumption, and tell me which block has the least evidence.

Prompts for the numbers

6. Unit economics

With these prices: [prices], variable costs per sale: [costs], and fixed monthly costs: [fixed], calculate contribution per sale, break-even volume, and the gap from [current sales]. Show each step.

7. Pricing scenarios

Show how break-even changes if I raise [price] by [amount] or cut [cost] by [amount], using only my numbers: [numbers].

Prompts for testing

8. Riskiest assumptions

From this canvas: [canvas], rank the five assumptions that would hurt the business most if wrong, and say which block each sits in.

9. Two-week tests

For each of these assumptions: [assumptions], design a test I can run in two weeks for under [budget], with the result that would change my mind.

10. Canvas update after a test

Here is my canvas: [canvas] and what happened in my test: [results]. Update the blocks, move lines from assumption to evidence or remove them, and tell me what to test next.

Fill the whole canvas from your notes

The Business Model Canvas Prompt: Nine Blocks From Your Notes combines all 10 prompts. Paste your idea, customer notes, prices and costs, channels, traction, resources, partners, and open questions. It returns a tagged nine-block canvas, unit economics, a fit check, ranked risky assumptions, three tests, a one-page text canvas, and answers to your open questions. The example works through a mobile bike repair service in Denver that is 143 dollars a month short of break-even and needs 12 to 13 tune-ups a month to cover its fixed costs.

Tips for using ChatGPT on a business model

• Bring interview notes with counts. "11 of 14 said" beats "people want".
• Do not let the model add market size numbers you did not paste.
• Rerun the canvas after every test, not once a year.
• Keep it on one page. If a block needs more than four lines, it is not clear yet.
