A good wedge is small enough to win and specific enough to grow from. How to pick one, sharpen it, and expand once it's working.
The wedge is the specific first problem you solve better than anyone. Every enduring company started with one. Founders who skip this step build broad products that lose to specialists in every segment.
Narrow enough that you can be clearly #1. Painful enough that customers pay to solve it. Frequent enough to build habit. Adjacent to a broader market you can expand into once you win the wedge.
Slack: file-sharing chat for gaming teams → all knowledge work. Figma: real-time design collaboration → all design/product tools. Superhuman: keyboard-shortcut Gmail for power users → email platform. Every winner started tiny.
Interview 20 customers. Rank the pains by frequency, severity, and willingness to pay. Pick the one where you can be 10x better than the current alternative. Cut features that don't serve that pain.
Once you own the wedge segment (>50% share) and customers ask for adjacent features. Not before. Premature expansion is the most common cause of stalled Series A rounds.
