The problem
You can buy growth or build it. Buy it and your CAC eventually says stop; build it and it compounds. Most companies never work out which engine they actually have — so they pour fuel into the wrong one.
Funnels leak; loops compound — and the businesses that scale know which they’re built on. Roll-ups print money until deal seven breaks the model. A viral coefficient of 0.4 quietly rules your entire trajectory. Enter a new market in the wrong sequence and you bleed for years.
Growth isn’t one lever; it’s an engine with a specific design. Name yours wrong and every tactic you try is aimed at the wrong place.

See it move
Model your viral coefficient — how many new users each user brings. At 0.4, growth fades the moment you stop paying for it; nudge it past 1.0 and the same product grows itself. Watch the loop flip from leaking to compounding as one input crosses the line. That single number tells you whether you have a growth engine or a growth budget.
