Product-Market Fit

Overview

Product-market fit means building something people actually want and will keep using. Without PMF, nothing else matters — not marketing, not growth, not fundraising.

Core principle: If less than 40% of users would be "very disappointed" without your product, don't scale. Fix the product first.

Announce: "I'm using product-market-fit to evaluate whether we're building the right thing."
