Disruptive Innovation
Overview
Most incumbents fail not because they make bad decisions, but because they make good ones. Clayton Christensen found that leading firms listened to their best customers, invested in high-margin segments, and were displaced anyway. The pattern: incumbents overshoot mainstream customer needs, creating a price window at the low end that a new entrant can enter profitably — and the incumbent cannot match without cannibalizing its own margins. Disruptors enter there, accumulate resources, and migrate upward.
Two paths exist: low-end disruption targets price-sensitive existing customers who are over-served; new-market disruption creates consumption among people who couldn't previously participate at all.
Compose with neighbors: s-curve-technology-adoption to assess incumbent vulnerability; pmf-crossing-the-chasm after identifying the entry point; blue-ocean-strategy when the attacker wants to reshape value dimensions; second-curve for the incumbent's response problem.
When to Use
Apply when: founder choosing market entry to avoid head-to-head; incumbent assessing low-price entrant threat; investor evaluating startup structural advantage; product team defining what to deliberately exclude from MVP; someone asks whether AI agents / usage-based (per-outcome) pricing are disrupting seat-based SaaS incumbents or just a feature they'll absorb.
When NOT to use: market requires absolute performance / no "good enough" threshold (aircraft engines, Class III devices); purely a price war with no cost-structure asymmetry; someone labeling every new entrant "disruptive" (Uber is sustaining innovation); insufficient data to assess overshooting.
