Leverage speed as your only advantage against entrenched competitors
Small startups competing against 15-20 year old incumbents have one currency that established companies don't: speed and urgency. Large competitors move slowly due to organizational inertia, technical debt, and process overhead. Use this speed advantage to rapidly reposition, pivot, and iterate while incumbents are still in planning meetings. Speed enables you to take market risks that large companies can't afford.
When to use
When entering a mature market with well-established incumbent competitors
Don't do this
Trying to out-resource or out-feature established players who have years of product development and larger teams
