Core Principle

Profitability is a superpower. It gives you infinite runway, clarity, and control. Spend less than you make. It sounds simple, but it's not easy. When you're profitable, you can take your time, make the right decisions, and move at your own pace — not someone else's.

Don't Spend Money You Don't Have

The Equation

Profit = Revenue - Costs

Make more than you spend: your company can keep going forever. Make less: you will eventually fail.

Two Types of Costs

Variable Costs (COGS)

Scale with each unit sold: payment processing, hosting, fraud prevention

Example: At Gumroad, ~40¢ of variable cost per $1 earned
