What are the classic mistakes founders make when picking a beachhead, and how do I avoid them?
The short answer
The three that kill people: picking the niche you can describe instead of the one you can reach, picking based on market size instead of your unfair advantage, and quietly serving three niches while telling yourself you've focused on one. The fix is brutal focus: name one segment, say no to the others in writing, and check that you can talk to a customer in that niche this week without a warm intro you don't have. As a starting point, if your "niche" needs two commas to describe, it's actually three niches.

Aulet turns beachhead selection into an explicit, sequenced process (market segmentation, then picking one beachhead, then profiling the end user) so you can see exactly where founders go wrong at each step. Most beachhead advice is a vibe. This is the one book that makes it a repeatable procedure with a worksheet, which is what you want the first time you do it.
The classic trap is picking a beachhead that is either too broad (you serve everyone 80 percent and no one enough to buy) or chosen on gut instead of a segmentation pass, so the framework forces you to list many segments before committing to one.
A real beachhead needs three things together: the customers all buy for similar reasons, they talk to each other (word of mouth), and you can serve the whole segment. Missing any one is a common mistake.
Your beachhead is a starting point, not your whole market. Aulet frames it as the door you walk through first, which takes the pressure off picking the theoretically biggest market.

Skok names the multi-niche trap head on and backs it with a real portfolio-company story: a startup that chased a 2,500-branch global bank it could not actually serve, burned resources, and only recovered once it refocused on a segment it could fully deliver for. It is a short, concrete read on why spreading across segments quietly kills you.
The 80 percent problem: a product that half-fits many segments gets people interested but not over the line to buy, so wide targeting looks like traction and converts like nothing.
Focus is hard precisely because it means saying no to attractive-looking deals, which is why founders keep making this mistake even when they know better.
Pick a segment with acute pain, budget, and urgency where you can deliver complete value, then expand later, rather than trying to be adequate everywhere at once.
