Synthesizing inputs into a viable business model.

Playbook Chapters
What You'll Learn How to update your Lean Canvas with real data and build a 12-month forecast with best/worst scenarios.

Synthesizing Everything

Lean Canvas v2 turns your early guesses into a business model backed by real data.

You started with guesses. Now you have proof. Here's how to put revenue, costs, and risks into one model you can test.

Lean Canvas v2: The Upgrade

Your original Lean Canvas from Playbook 01 was based on hypotheses. Now you update it with validated data:

Canvas Section Original (Guess) Updated (Validated)
Revenue Streams "Subscription" "Hybrid: $50/mo + $0.02/token overage"
Cost Structure "Hosting, salaries" "Inference: $5K/mo, Salaries: $20K/mo, Marketing: $5K/mo"
Key Metrics "Users, revenue" "Paid CAC <$300, Payback <9 mo, Churn <3%"
Unfair Advantage "First mover" "Proprietary dataset of 50K validated samples"
The Specificity Test

If your canvas still contains vague terms like "subscription," "hosting," or "first mover advantage," you haven't finished feasibility. Every box should contain specific, testable numbers.

The 12-Month Financial Projection

A good business model needs a financial plan. You won't predict exact numbers—but you can prove the math works.

Build from Inputs

Start with real inputs:

Traffic × Conversion = Customers

Customers × Price = Revenue

Test Changes

See what happens when inputs change:

"What if conversion drops 20%?"
"What if churn rises to 5%?"

Outputs

The model shows:

Monthly profit/loss

Cash flow over time

Key metrics dashboard

Scenario Planning

Investors don't trust one forecast. They want to see a range that shows you know what could go wrong.

Base Case

Realistic numbers based on what others see in your market.

Your "most likely" outcome—not too hopeful, not too gloomy.

Best Case

Strong growth, low costs, fast customer adoption.

What happens if everything goes right?

Worst Case

Flat growth, high churn, slow adoption.

Can you survive if this happens?

The "Default Alive" Test

Can you survive the worst case without raising more money? If yes, that's powerful. It shows investors you can weather storms on your own.

The Integration Checklist

Before moving to the Go/No-Go decision, verify you've integrated all components:
