Unit economics, churn, runway, the first hire, rounds and price wars — in plain words, with examples. Every post ends with how the same thing works in Runway 200, where you can test it on your own decisions.
What CAC, LTV and churn are, how to calculate them on a napkin, and why early on these numbers are an estimate, not a fact.
What a startup's runway is, how to calculate it in a minute, why it's shorter than it looks, and how many months before zero to start looking for money.
What to do when a competitor undercuts you: cut your price, hold it, or retreat into a niche — and why a discount brings different customers, not cheaper ones.
What founder dilution is, how it adds up over several rounds and employee options, and why the percentage matters more than the amount on the term sheet.
When to make a startup's first hire, whom to hire first — an engineer, a salesperson or support — and why a new hire costs money long before paying off.
How to run customer interviews, what to ask, how many conversations you need, and why five glowing reviews prove nothing yet.
How to calculate customer churn, why you look at it by cohort, and why with steady churn your customer count stops growing no matter how much you spend on ads.
Why Runway 200 has no “do the sensible thing” button, and why every fork has a “do nothing” option.
