You’ve got an idea. Maybe it’s niche. Maybe it’s weird.

But can it actually make money?

In this episode of the Unsexy Entrepreneurship Podcast, Charles Harris (CPA, business owner) and Dr. Seth Jenson (PhD in business strategy) walk you through how to size your market—and how to think about scale, opportunity, and profitability in a practical, non-fluffy way.

They use a real example: a high school student who wants to launch a floral wreath and porch-decorating subscription business. What starts as a “cute” local idea turns into a potentially $24 billion market—and you’ll hear the logic behind every step.

💡 You’ll Learn:

• What “Total Addressable Market” (TAM) actually means—and how to find yours
• The difference between TAM, SAM, and SOM (yes, these matter)
• How to market-size local service businesses with free tools
• Why market size matters less than you think
• How small numbers can still build a big business
• The overlooked power of niche domination
• Real examples from law firms, music schools, and high-end porch decorators
• How to back-calculate revenue goals based on client count
• Why 40 clients could be all you ever need

Whether you’re planning a tech startup or a seasonal service hustle, this episode gives you the clarity you need to evaluate your idea like a strategist—and start building with confidence.
