A structured decision system for solo service founders.
Six sections, 159 formulas, one clear verdict on whether your business is viable.
The Workbook guides your thinking. The Spreadsheet does the math.
The Quick Start Guide shows you how to use both.
Guided worksheets for market validation, competitor analysis, financial planning, unit economics, acquisition strategy, and risk assessment.
The calculation engine. Enter your numbers in yellow cells — scores, thresholds, stress tests, and your final verdict calculate automatically.
Setup instructions, the color-coded cell guide, FAQ, and complete terms of use. Everything to get started immediately.
& two fully worked examples
A completed sample analysis using a fictional solo founder. See exactly how each section is filled out — from market validation to risk assessment.
Pre-filled with sample data so you can study every formula, score, and verdict in action before entering your own numbers.
What It Does
Every feature exists because real service businesses fail in predictable, preventable ways.
One clear answer — Launch Ready, Nearly Ready, Gaps Exist, or Not Ready — based on your total score across all six sections.
Auto-forces "Not Ready" if contribution margin is below 30%, capacity exceeds 120%, or runway is under 2 months.
Reveals what you actually earn per hour after admin, prep, communication, and all the time you're not counting.
Models what happens when revenue drops 30%, costs rise 10%, and you can't work for 2 weeks. Shows if your plan survives.
Calculates exactly how many clients you need per month and checks that number against how many you can physically serve.
Post-launch tab tracks actuals vs. targets each month with threshold alerts — because a viable business can break within 90 days.
We strongly recommend Microsoft Excel 2016 or later. The Spreadsheet uses cell protection and locked formulas that Google Sheets may not fully support. If you must use Google Sheets, make a backup copy first.
4–6 focused hours spread across 2–3 sessions. Section L requires real conversations with potential clients — if you haven’t done that yet, plan for 1–2 weeks of elapsed time.
