Momentum
In physics, momentum equals mass times velocity. In growth, it's the force that makes good programs get better and bad ones get worse. Every growth system is either compounding or decaying. There is no steady state.
p = m × v
momentum = mass × velocity
Growth Momentum = Market Position × Growth Rate
Core Principle
Compounding vs. the treadmill
A growth program with momentum becomes easier to sustain and harder for competitors to disrupt. Established brand recognition, growing word of mouth, compounding content assets. Every dollar invested yields more than the last.
A program without momentum requires constant force just to maintain position. Every dollar invested yields less than the last because you're fighting inertia. That's the treadmill.
Diagnostics
How to recognize momentum
Momentum shows up in your metrics, but you have to know where to look. These two columns are the difference between a growth engine and a spending engine.
Strategy
Building momentum
You can't buy momentum directly. You can only create conditions for it to develop.
Invest in mass before velocity
Market position is your "mass." A strong brand, clear positioning, and established trust make every campaign more effective. Investing in velocity without mass just burns energy.
Compound, don't campaign
One-off campaigns create spikes, not momentum. Build assets that compound: content that ranks long after publication, communities that grow through network effects, partnerships that expand reach over time.
Reduce friction
Momentum and friction are opposing forces. Every point of friction in your funnel dissipates momentum. A 10% conversion improvement often beats a 10% increase in top-of-funnel spend.
Critical Threshold
The inflection point
Momentum has a critical threshold. Below it, every dollar of reduced investment causes disproportionate decline. Above it, the system becomes self-sustaining.
This is why "should we scale growth spend?" is often the wrong question. The right question: "Have we achieved escape velocity?" Scaling spend before you have momentum just burns cash faster. Scaling after you have it compounds your advantage.
The question isn't "should we spend more?"
The question is: "Have we achieved escape velocity?"
Self-Assessment
Five questions that reveal the truth
Is our CAC trending down over time, or up?
What percentage of pipeline comes from organic vs. paid sources?
How much of our content generates leads 6+ months after publication?
Are our sales cycles getting shorter or longer?
Would reducing growth spend by 20% reduce results by more or less than 20%?
If more: you don't have momentum. You have a treadmill.

Related forces
Momentum doesn't operate in isolation. Friction opposes it. Mass amplifies it. Understanding the interplay is how you build systems that compound.
