solely focusing on serving the needs of one niche first before expanding to others—is a market wedge.

A wedge is a method for spending limited resources strategically. You pick one thing, do it well, then use that momentum to expand later.

“product wedges,” where you make your initial product as easy to adopt as possible—even to the point where you sacrifice profitability and defensibility

A market wedge, on the other hand, is basically the inverse of a product wedge. Instead of sacrificing power for growth, you sacrifice growth for power, and focus on a small niche within the larger market you’d eventually like to reach.

By limiting who you aim to serve, you have a better chance of developing some power within that market early, like network effects, brand, economies of scale, etc.

List the main types of market wedges (geography, topic, product category, community, demographic) with a few good examples for each—and some counter-examples.
