Pro tip, from the book
The most important burn rate insight is not the number itself — it is the break-even revenue calculation. Knowing that you need 45,000 in monthly revenue to reach zero net burn gives you a concrete target that connects financial health to sales activity. Every founder should know their break-even revenue number without having to look it up.
Who should run this prompt
Module role profileWho should review your numbers and financial narrative? Numbers do not lie — but they can mislead when read through the wrong lens. A CFO and an investor look at the same P&L and ask completely different questions. A customer's finance team looks at your pricing and asks a question neither of them thought of. Use this page to choose who is in the room before you present, model, or decide based on your financial data.

How to make any role sharper
- Add years of experience: "...with 15 years in enterprise SaaS" produces different depth than just the title.
- Add what they care most about: "You care most about [X]" shapes every word of the output.
- Add their communication style: "Be direct. Flag risks first. No jargon." changes the tone entirely.
Use this when
The problem it solvesYou are running a funded startup or a business with variable revenue and you do not have a clear, current view of how many months of operating capital you have left. Financial decisions are being made without a clear runway calculation.
How the framework works
From the printed pageBurn Rate is the rate at which a company is spending its cash reserves above revenue, either Gross Burn (total monthly expenditure) or Net Burn (monthly cash lost after revenue). Runway is the number of months until cash reaches zero at the current net burn rate. These two numbers are the most fundamental financial metrics for any pre- profitability business. Every strategic decision, hiring, marketing investment, product bets, changes the runway. AI can help model the impact of decisions on runway and identify the break-even scenarios.
The method, in four moves
Do these in orderCalculate net burn monthly, not quarterly, cash positions change faster than quarterly reviews reveal.
Build your runway calculation from the bottom up, know exactly what each expense line contributes to burn.
Model three burn scenarios: current trajectory, growth scenario (higher spend + revenue), and conservation scenario.
Set a runway alert threshold, when you hit 9 months of runway, fundraising or cost review must begin immediately. Waiting until you hit 9 months to start fundraising is already too late, fundraising itself takes months, and a shrinking runway makes you negotiate from weakness. The threshold triggers action, it doesn't wait for it.

When this page changes, your copy of the book does not have to.
The book prints the framework. This page keeps it — and keeps the prompt current, because prompting technique moves faster than print does. When it moves, this page is rewritten and the code in your copy keeps pointing at it. No second edition, no replacement purchase, no account.
If something here looks wrong — a prompt that does not match its framework, a figure that reads oddly — tell Raphy. That correction reaches every printed copy at once.
