Product Segmentation seems to be an integral part of Market Segmentation. For a startup, product segmentation may be a wise option.

For a startup it is better to start with a niche market. So better to focus on market segmentation

At its simplest, market segmentation is the process of dividing a market into segments and directing a marketing mix to a particular segment, rather than the total market. In line with your question, product segmentation has special relevance for the retail sector, where the range of the offering (products + services) is very wide. For a startup it is important to start with market segmentation or market niche.

Dear Ansam A. Abdulhussein, your question is very topical to many start-up companies. As a financial controller who has advised many start-ups, I can say that market segmentation is a priority for new companies. In a specific market, we usually have a group of products or services that we can offer for sale. Of course, the new company should know what it wants to sell and to whom, but in practice, the initial plans are significantly changed. New companies often recognize the needs of consumers and the dynamics of changes on the market well only in the first 3 years. In this initial period, they often change the product offer, because they notice that something is not working for them, or that their resources of production factors are much better for offering slightly changed goods or services that even their owners did not take into account at the beginning of their operation on the market as an opportunity for success.
