Vital Sign 05 of 05
Growth Oxygen™
The sustainability of your growth. Whether expansion strengthens your business or quietly compresses margins and shortens runway.
Why It Matters
Revenue growth feels like progress. But when expenses rise faster than revenue, margins compress silently. Growth becomes a burden instead of a benefit — consuming cash faster than it generates value. By the time most owners notice, runway has already shortened.

What Growth Oxygen Measures
Three dimensions of growth health that determine whether expansion helps or hurts your business.
Growth Efficiency
Whether revenue growth outpaces expense growth. When expenses rise faster than revenue, growth is costing more than it earns.
Contribution Margin
How much profit each new dollar of revenue generates. Below 30% means growth is adding revenue but removing profit.
Runway Impact
Whether growth extends or shortens your cash runway. Sustainable growth adds time; unsustainable growth consumes it.

Questions about Growth Oxygen
What does Growth Oxygen measure?
Three readings. Whether revenue growth outpaces expense growth. The margin on new revenue, where below 30% means growth is adding revenue but removing profit. And whether growth extends or shortens the cash runway.
How can growth hurt a business?
When expenses rise faster than revenue, margins compress silently and growth consumes cash faster than it generates value. Growth becomes a burden instead of a benefit, and most owners notice only after it has shortened the runway.
What is the difference between Growth Oxygen and Margin Temperature?
Margin Temperature reads what you keep on today's revenue. Growth Oxygen reads what the next dollar of growth does to margins and runway.
What counts as sustainable growth here?
Growth that adds time: revenue rising faster than expenses, a healthy margin on each new dollar, and a runway that lengthens rather than shortens as the business expands.
