Disruptive Innovation
Also called Disruption
Clayton Christensen's idea: a smaller entrant with a simpler, cheaper offering serves overlooked customers, then improves until it displaces established leaders who ignored it.
Why it matters
Disruption explains how startups beat incumbents who seem unassailable, by starting where the giants do not care to compete. Understanding it helps founders find the underserved foothold from which to grow up-market.
For example
Netflix started with mail-order DVDs for underserved customers, then improved into streaming and displaced the video-rental incumbents who ignored it.
