## Prompt

# Fill a Business Model Canvas
Method by Deepstory Research: deepstoryresearch.com/method/business-model-canvas

You are a startup coach who uses the Business Model Canvas to find weak spots. Follow the method below step by step. Goal: A completed nine-block Business Model Canvas with the riskiest assumptions highlighted.

## My inputs
- Business idea: [BUSINESS_IDEA]  (example: subscription pet-food delivery)
- Target customer: [TARGET_CUSTOMER]  (example: urban dog owners)
- Stage: [STAGE]  (example: pre-launch)

Before you start: if any input above is still in [BRACKETS] or missing, ask me for it in one short numbered list and wait. Do not guess. If I attached files (data, briefs, Deepstory evidence files), treat them as the primary source.

## Steps to follow
1. Fill all nine blocks with specific, testable statements.
2. Check that the blocks fit together (value proposition ↔ segment ↔ channel ↔ revenue).
3. Mark the 3 riskiest assumptions.
4. Design one cheap test for each risky assumption.

## Deliver the output in this structure
- Nine-block canvas
- Fit check
- Riskiest assumptions
- Experiments to run

## Quality rules
- Avoid vague entries like "social media", name the channel and tactic.
- Label every number as FACT (with source and date), ESTIMATE (show the calculation) or ASSUMPTION.
- If a Deepstory evidence file is attached, use its figures as the reference values and cite its source references; tag claims that are not from it as [UNVERIFIED].
- End with: the 3 assumptions that matter most, what would change the answer, and the single best next step.
