Beachhead Market

The term comes from military strategy: you don't try to invade an entire coastline at once, you secure one small beach, then expand out from a position of strength. Applied to startups (popularized by Geoffrey Moore's Crossing the Chasm), the same logic keeps a small team from spreading itself across a market it cannot yet serve well. A good beachhead is narrow enough that you can become the obvious choice for it: identifiable (you can find and reach these people), underserved (they feel the problem acutely and no one solves it well for them), and expandable (winning here gives you a credible path to adjacent segments). "Small businesses" is not a beachhead. "Ten-person creative agencies billing hourly on Airtable" is. Facebook's beachhead was Harvard undergraduates, not "college students" and not "everyone with an email address." It expanded to other Ivy League schools, then all US universities, then the general public, each expansion built on proof from the last. Superhuman's beachhead was busy operators and investors who lived in their inbox and could justify $30 a month for speed, long before it positioned itself as email for everyone. For a pre-launch team, picking a beachhead means turning down customers who technically fit but dilute focus. If your first ten paying customers differ across role, company size, and use case, you don't have a beachhead yet, you have scattered interest.

Superhuman's beachhead was time-strapped executives and investors willing to pay for speed. It did not try to serve casual email users until years later, after it had proven the model with a segment that had money and an acute problem.
