Founders Who Changed How We Think

The most instructive stories in product building aren't the ones about success - they're the ones about the moments when a founder held a conviction the market disagreed with, and turned out to be right.

Every product that mattered started as someone's unpopular opinion. The insight that made Airbnb work - that strangers would rent their homes to other strangers - was so counterintuitive that it was rejected by multiple investors before finding believers.

Most transformative products look like failures before they look like successes. The pattern repeats often enough to be worth internalising: early adoption is slow, critics are loud, and then something tips.
