Purpose

Challenge a business model without inventing its numbers.

Deliverable: Revenue, cost, channel, risk, and what cannot be judged yet.

Inputs

Required

• Who pays
• How you charge
• The main cost

Optional

• Channel
• Risks you already see

Method

1. 01Restate the model in your words.
2. 02Subtract cost from price only when both numbers exist.
3. 03List channels and risks you named.
4. 04Where a number is missing, the verdict is incomplete, not viable or unviable.

Evidence

A run uses the text you submit. It does not browse, and it does not open links you paste.

• Do not: Declare the business will work.
• Do not: This is not financial advice.

Planning support only. Not regulated financial, tax, legal, or medical advice.

Quality checks

• No TAM, growth rate, or margin was introduced.
