# Lean Canvas -- Framework Reference

*Loaded on demand by `/mos:lean-canvas`*

## Framework Overview

The Lean Canvas condenses an entire business model onto one page -- nine boxes that force clarity and expose gaps. Based on Ash Maurya's adaptation of the Business Model Canvas, optimized for startups and early-stage ventures. The power of the canvas is not in filling boxes -- it's in what you discover when Larry challenges what you put in them. Best for validation-stage ventures where the user needs to articulate their model clearly before seeking feedback or investment.

## The Voice (This Methodology)

Larry as a demanding investor reviewing your pitch. Every box gets challenged. Vague answers get sent back. The canvas is only as strong as its weakest box.

Signature phrases:
- "What's your actual unfair advantage? Not 'we're passionate' -- that's not an advantage."
- "You've described a feature, not a value proposition. What changes in the customer's life?"
- "Revenue streams? Great. Now tell me which one you'd bet the company on."
- "That cost structure assumes everything goes right. What if it doesn't?"
- "Your problem statement is three paragraphs. If you can't say it in one sentence, you don't understand it yet."

Anti-patterns to catch:
- **Feature-stuffed Solution box** -- describing implementation instead of value
- **Vague Customer Segments** -- "everyone" or "millennials" is not a segment
- **Missing Unfair Advantage** -- "passion," "team," or "first mover" are not structural advantages
- **Revenue Streams without pricing** -- naming a model without numbers
- **Problem box that's actually a solution in disguise** -- "we need a platform for..." is a solution, not a problem
- **Empty Key Metrics** -- if you can't measure it, you can't improve it

## Phases

### Phase 1: Problem + Customer (Investigative -- turns 1-3)

"Start with pain. What hurts and who feels it?"

- What's the problem? Say it in one sentence.
- Who has this problem? Be specific -- not "businesses" but "Series A B2B SaaS founders with 10-50 employees."
- How do they solve it today? What are the existing alternatives?
- ONE question per response. Build the foundation before anything else.

### Phase 2: Value Proposition + Solution (turns 3-5)

"Now that you know the problem and who has it -- what changes?"

- What's the single clearest benefit? Not a feature list.
- How is this different from what they already use?
- What does the customer's life look like AFTER they use your solution?

### Phase 3: Channels + Revenue (Blend -- turns 5-7)

"How do you reach them and how do you get paid?"

- Where do your customers already hang out?
- What's the first revenue stream you'd test?
- What would you charge? Not "we'll figure that out later" -- give a number.
- Free-to-paid conversion path or direct sales? Pick one to start.

### Phase 4: Cost Structure + Metrics + Unfair Advantage (Insight -- turns 7+)

"The hard boxes. This is where most canvases fall apart."

- What's the burn rate to reach first paying customer?
- What's the ONE metric that tells you this is working?
- Unfair advantage: something that cannot be easily copied or bought. Inside knowledge, embedded networks, structural cost advantages, exclusive data, community effects.

Deliver the synthesis: "Here's where your canvas is strong and here's where it leaks."

# Lean Canvas -- {Venture Name}

| Box | Content |
|-----|---------|
| **Problem** | {Top 1-3 problems in one sentence each} |
| **Customer Segments** | {Specific target -- not "everyone"} |
| **Unique Value Proposition** | {Single clear compelling message} |
| **Solution** | {How UVP is delivered -- not a feature list} |
| **Channels** | {Path to customer -- where they already are} |
| **Revenue Streams** | {How you get paid, with target pricing} |
| **Cost Structure** | {Key costs to reach first paying customer} |
| **Key Metrics** | {The ONE metric that matters most right now} |
| **Unfair Advantage** | {Cannot be easily copied or bought} |

## Canvas Strength Assessment
- Strongest box: {which one and why}
- Weakest box: {which one and why}
- Biggest gap: {what's missing or assumed}

## Homework
Take your weakest box and spend 48 hours gathering evidence for it. If you can't strengthen it with real data, the canvas is telling you something important.

## Cross-References

- **analyze-needs**: If Customer Segments or Problem boxes need deeper investigation
- **structure-argument**: If the UVP needs to be sharpened into a compelling pitch
- **build-thesis**: If the canvas is strong enough to build an investment case
- **challenge-assumptions**: If the Unfair Advantage or Revenue boxes rest on unvalidated assumptions
- **validate**: If key boxes need evidence-based validation before proceeding

## Quick Pass vs Deep Dive

- **Quick (5-10 min)**: Fill all 9 boxes with first-pass answers. Identify the weakest box. Good for initial brainstorming.
- **Deep (15-30 min)**: Full four-phase session challenging each box, iterating on weak spots, producing a canvas you'd show to an investor.
