As of 13 August 2026, AI can define a business model for your UK company.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 1 hour until you can act on the result.

   How to actually do it

   1. Open a document or spreadsheet and gather your current offer, customer descriptions, sales records, prices, direct costs, fixed costs, sales channels, delivery constraints and competitor notes.
   2. Paste the gathered information into the prompt, leaving unknown fields marked as unknown rather than filling them with guesses.
   3. Run the prompt in ChatGPT, Claude or Gemini and save the business model canvas, the three options, the calculations and the list of assumptions.
   4. Compare every stated fact and calculation against your accounts, price list, contracts, order records and operating costs, and correct any mismatch in the draft.
   5. Speak to prospective or existing customers using the proposed tests, record their answers and outcomes, and replace unsupported demand assumptions with the evidence you collect.
   6. Put the surviving option and its assumptions into a spreadsheet, then change each important input to see whether the conclusion still holds.
   7. Ask an accountant about tax, funding, cash flow and financial projections, and ask a solicitor about contracts, intellectual property, data protection or company structure where those issues affect the model.
   8. Send the final canvas, evidence log, tested assumptions and action plan to the people who will make the decision, and record which option you are adopting and why.

   Prompt

   Help me define a practical business model for my UK company. Treat this as a working hypothesis, not a proven plan, and do not invent facts, customers, market figures, costs, laws or sources.
   
   Company and offer:
   - Company or project: [name and short description]
   - What we sell: [product or service]
   - Current stage: [idea, pre-revenue, trading, or established]
   - Target customers: [specific customer groups]
   - Geography: [UK region or wider market]
   - Current sales or usage evidence: [facts, if any]
   - Price or proposed pricing: [amounts and what customers receive]
   - Direct costs: [known costs per sale or delivery]
   - Fixed costs: [known monthly or annual costs]
   - Sales channels: [how customers find and buy from us]
   - Delivery and operations: [people, suppliers, technology and constraints]
   - Competitors or alternatives: [names or descriptions]
   - Company objectives and constraints: [goals, budget, capacity and timescale]
   
   Produce:
   1. A one-sentence description of the customer, problem, offer and outcome.
   2. A business model canvas covering customers, value proposition, channels, customer relationships, revenue, key resources, key activities, partners and costs.
   3. Three materially different business model options, including who each suits, how it makes money, its main assumptions and its main risks.
   4. A simple contribution-margin model using only the figures I supplied. Show the formula and label every missing input instead of estimating it.
   5. The strongest current option, with the evidence supporting it and the assumptions that could make it wrong.
   6. The five highest-priority tests to run with real or prospective UK customers, including the question, method, pass or fail signal and what decision each result would change.
   7. A 30-day action plan in weekly stages, with outputs and an owner for each action.
   8. A short list of questions I must answer before committing money.
   
   Separate facts I supplied, assumptions, calculations, recommendations and unknowns. Flag any point that needs checking with an accountant, solicitor or other specialist. This is not professional advice.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
