Two companies grow 25%. One compounds, one is a time bomb — the number won't tell you which.

“Revenue grew 25%” is where most people stop reading and start valuing. It’s exactly the wrong place to stop, because 25% is a result, not an explanation — and two identical headline numbers can hide two completely opposite businesses.

Pull the growth apart and you find it comes from a handful of very different sources: new customers landed, existing customers expanding (more seats, or more usage), and price increases — plus, for many big names, acquisitions bolted on. These aren’t an accounting identity; they’re a management lens. But the lens matters enormously, because each source carries a different quality. Growth from existing customers expanding on their own is the compounding machine turning. Growth rented from a discount-driven land grab, or bought with an acquisition, or squeezed out of annual price hikes into a saturated base, is a very different animal wearing the same 25% costume.

The single most important cut is organic vs. acquired. A company that grows by buying other companies can post beautiful top-line numbers while its underlying business stalls — and it pays for those numbers in dilution, integration risk, and goodwill. Salesforce is the textbook case: a genuine giant at ~$41.5B in revenue, but one whose history is threaded with huge acquisitions (Tableau, Slack, MuleSoft), and whose organic growth has slowed to roughly single digits (~9.5%). None of that makes it a bad company — it makes “how much of the growth is organic?” a non-optional question. A management team that highlights total growth while quietly burying the organic rate is telling you something.

There’s a subtler cut still — new-customer growth vs. expansion growth. A company growing mostly by landing new logos is on a treadmill: it has to re-win that pace from scratch every year. A company growing because existing customers expand on their own is the compounding machine turning, and the market rightly pays more for it. Two identical 25%s — one bought with a sales army, one thrown off by a happy installed base — are simply not the same asset.

The second cut is usage vs. price. Growth from customers genuinely doing more on your product is durable; growth from raising prices on a captive base is borrowed from the future and caps out. So the discipline of this chapter is simple: never take a growth number at face value. Decompose it — organic vs. M&A, usage vs. price, new vs. expansion — and cross-check it against cRPO to see whether contracted future business agrees with the story. The rate tells you how fast. Only the composition tells you how real.
