What is a niche market?

The idea of targeting a niche — a specific, well-defined segment of a broader market — is widely recommended for early-stage businesses, but the rationale behind it is not always explained well. Many new founders assume that targeting a narrow audience means limiting their potential, when in practice the opposite is often true for businesses competing against established players.

A niche market is a defined subset of a larger market, characterised by a specific customer profile, a shared set of needs, or a particular context in which a product or service is used. Serving a niche well means becoming the preferred option for a specific group rather than a mediocre option for everyone. This focus typically leads to stronger word-of-mouth, more relevant marketing, lower customer acquisition costs, and a clearer competitive position than a broad market approach.

Choosing the right niche requires understanding both the size of the opportunity and whether it is large enough to build a sustainable business within. Niches that are too narrow may cap revenue potential; niches that are too broad are simply markets. Our guides to market positioning and early customer strategy help UK founders identify and assess niche opportunities that are worth building a business around.
