Beachhead
A hyper-specific first segment you dominate completely before expanding to adjacent segments that share buyers, channels, or problems (Moore’s bowling pin). PH automotive is WPH’s beachhead; SEA automotive and PH conglomerate enterprise are the next pins.
Source: Geoffrey Moore, Crossing the Chasm (1991). Moore’s D-Day metaphor: don’t spread across the whole market — win one narrow segment so completely that you’re the default choice there, then use that stronghold to take the next segment.
