Beachhead Market
Also called Beachhead and Beachhead Niche
A small, specific initial market you can dominate first, then use as a base to expand into adjacent segments. From military strategy, securing a beach before advancing inland.
Why it matters
Trying to serve everyone at once usually means winning no one; a beachhead lets a small startup become the clear leader of a narrow segment. Owning that foothold builds the references, learning, and cash to expand from strength.
For example
Facebook started only at Harvard, dominated it, then expanded college by college, rather than launching to everyone at once.
