The Lean Business Plan Worksheet
One-page Lean Canvas + 7-section worksheet you can draft in 60 minutes. The order I would use today, distilled from 4,500+ ideas founders have run through Preuve AI.
1 Lean Canvas. 7 plan sections. 60 minutes.
Each section has prompts and space to fill in. Draft them in evidence order, executive summary last.
Market Analysis
Draft 1stTAM, SAM, SOM with sources. Bottom-up SOM beats top-down TAM every time.
Product or Service
Draft 2ndOne sentence on what it is. Three on how it works. One on what makes it defensible.
Marketing & Sales
Draft 3rdOne channel you have already tested. Pricing with two real comparables. First-sale path.
Financial Projections
Draft 4th18-month cash flow, 3-year P&L, break-even month. Skip the 5-year forecast.
Company Description
Draft 5thMission in one sentence. Legal structure. Where + when founded.
Organization & Management
Draft 6thFounder background in three sentences. Open roles. Advisors.
Executive Summary
Draft LASTOne paragraph compression of every section. Write this LAST. If it does not flow, the underlying sections are weak.
Why I made this
I have read hundreds of first business plans. The same pattern shows up: a 30-page document written before the founder talked to ten customers. Polished, useless, two weeks of work.
The fix is not another template. The fix is the right format and the right order. A one-page Lean Canvas captures the assumptions. The 7-section structure draft in evidence order, executive summary last, gets you from blank page to first draft in 60 minutes.
This worksheet is what I would hand a founder on day one. The Lean Canvas on page one, the 7-section worksheet on pages two and three. No filler. Print it, fill it in pencil, refill after every five customer interviews.
Both will save you from writing a plan that means nothing.
