This is where in see 90% of companies failing when they present to investors. They lack the forethought and planning to articulate a long-term strategy to enter and expand their market.
Two of the most important strategic choices are your GTM and your long-term market entry and positioning. Most lack understanding of the difference. The first is essentially your MVP product and its positioning. The second is usually a multi-step process that takes two to four years to unfold. It is a Trojan Horse in most cases because you are entering a small market (niche) as a startup and expanding it exponentially in years 3 to 5. You do not want to attract the attention of the 800-pound gorillas in your market space and you want cooperation from distribution channels generally. You need total differentiation and white space positioning.
It is rare that a company will be a one product company with a single niche market. You have already learned that even large companies do not go after large, vertical markets early, if ever. Segmentation and niching is needed due to the huge cost of marketing and noise of competition.
All the tools you need to understand and plan a market entry strategy that will attract capital, top people and allow scaling.
