"Find your wedge" is one of those phrases founders nod along to and then ignore. The wedge is the specific, narrow thing you can credibly be the best at today — the entry point that makes the rest of the market takeable later.
Map the landscape, don't rank it
List every direct competitor, indirect alternative, and the do-nothing option. Note what each is genuinely good at, and where users complain in public (reviews, subreddits, Twitter). You're looking for consistent gripes, not scores.
Find the crack, not the category
The wedge lives where a specific customer, doing a specific job, is badly served today. "SMBs need better CRM" is not a wedge. "Solo real-estate agents on Google Sheets can't answer 'which listing is closest to closing?' without opening five tabs" is close to one.
Test the wedge in customer language
If prospects can't repeat back your positioning without prompting, it isn't a wedge yet — it's a paragraph. Rewrite until they can.
Widen only after you own the wedge
The pattern that works is: own a narrow segment, earn a reputation there, then expand into adjacent jobs the same customer already has. Widening before you've earned the wedge is how positioning collapses.
