Why Focus on Untapped Niches?

Untapped niches mean less competition and a more targeted customer base, which makes it easier to stand out and build loyal buyers. They often require less upfront investment and can be managed part-time or scaled up as you grow.

Plus, niche products often command better prices because they solve specific problems or appeal to passionate communities.
