Finance

6 guides

Startup finance is not accounting. It is a small set of relationships — what a customer costs, what a customer is worth, how fast cash leaves, what the market is willing to pay for the resulting growth — and almost every strategic decision reduces to one of them. These guides work through those relationships with real numbers rather than definitions, so the arithmetic is visible and you can run it against your own business.

The recurring lesson is that the levers are not equally powerful. Churn compounds monthly and dominates every long-run forecast. Price falls almost entirely to gross profit and is the cheapest change available. Acquisition spend, which is where most attention goes, is usually the weakest of the three. Knowing the order of magnitude before you allocate is worth more than any individual tactic.
