The Walkthrough

Step 1: Brain Dump to AI

What to do: Open Claude and tell it everything about your business idea in plain language: what you want to sell, who your customer is, how you’ll make money, what makes you different. Don’t worry about structure.

Why you’re doing it: Claude will organize your raw thoughts into a structured plan. You just need to provide the raw material.

Step 2: Generate the Plan Framework

What to do: Ask Claude: “Turn my business description into a complete business plan with these sections: Executive Summary, Problem & Solution, Target Market, Revenue Model, Marketing Strategy, Operations Plan, Financial Projections (3-year), and Team. Write each section in 200–300 words.”

Why you’re doing it: This gives you a complete first draft covering every section investors and banks expect to see.

Step 3: Build Financial Projections

What to do: Ask Claude: “Create a 3-year financial projection for [your business]. Include monthly revenue, costs, and profit for year 1, then annual for years 2–3. Assume [your pricing] and [your target number of customers per month].” Then paste the numbers into Google Sheets.

Why you’re doing it: Financial projections are where most people quit. AI makes reasonable assumptions and gives you a starting framework to adjust.

Step 4: Refine and Validate

What to do: Read through the entire plan. Challenge every assumption. Ask Claude follow-up questions: “Is this revenue estimate realistic for a [business type] in [city]? What am I missing?”

Why you’re doing it: AI gives you structure. Your local knowledge and common sense make it real.

Step 5: Format and Export

What to do: Ask Claude to format the final version as a professional document. Copy into Google Docs and add your branding.

What to Do If It Doesn’t Work

  • Problem: “The financial projections seem unrealistic.” — Give Claude more specific inputs: your actual costs, your actual pricing, your actual capacity.
