Crossing the Chasm

Geoffrey Moore identified the single biggest reason technology companies fail: the chasm between early adopters and the mainstream market. Early adopters buy because they love new technology. The mainstream market buys because they need to solve a problem and their peers have already validated the solution. The gap between those two buyer personas is a death trap, and most startups fall into it.

Moore's solution — pick a narrow beachhead segment, dominate it completely, then use that position to cross into adjacent segments — remains the standard go-to-market playbook for technology companies three decades later. If you are selling anything innovative to anyone, you need to understand why the early market and mainstream market are fundamentally different animals and why the strategy that works for one will fail catastrophically with the other.
