Advantages of a Niche-Strategy

There are several advantages of starting out with a smaller market. These are especially useful for early-stage startups:


By focusing on a smaller, more targeted market, you can better understand the needs and pains of your customers. You'll make it easier to tailor your product or service to meet their specific needs.

Lower Customer Acquisition Costs (CAC)

Smaller markets allow you to gain customers at a lower cost. You can use targeted marketing campaigns to reach your target audience with less competition.

Immediate feedback cycles

You can receive immediate, direct feedback from your customers.  This will help you iterate and improve your product quickly.


A niche market can be a powerful source of word-of-mouth referrals and recommendations. It will help you build a strong reputation and attract new customers more easily.

Pitch your market size convincingly to investors

To pitch your market size to investors, it is important to:

Focus on potential

Highlight the potential size of the market and show how your product or service is poised to capture a significant share of it.

Be realistic

Avoid overstating the size of your market or being overly optimistic about your growth prospects. Investors appreciate honesty and transparency.

Use data

Use data to support your market size claims, such as market research reports, surveys, or industry analysis.

Create an expansion story

Illustrate how your market will grow and evolve in the future and how your product or service will continue to capture a larger share of it.
