Money Desk
Find out if the math works: acquisition cost, lifetime value, payback, runway, and break-even on one page.
Not tax, legal, or investment advice.
A one-page money check with your own numbers: cost to win a customer, lifetime value, the ratio, months to pay back, months of runway, and break-even revenue.
Founders feel the money problem before they can name it. The math is simple once the numbers are in one place.
The Money desk asks for the numbers you have, shows every formula with your figures in it, marks which inputs are estimates, and ends with the one finding that matters most this month.
This is arithmetic on your numbers. Not tax, legal, or investment advice. Check decisions with your accountant.
