Today, I learned about two entrepreneurs who have built interesting (separate) businesses based on their passion. They create 30-second to 1-minute videos in which they review board games and card games, explain how to play them, and record themselves playing them.

The interesting thing is their revenue model. These entrepreneurs each have millions of followers across various social media platforms. Their followers, I assume, are interested in finding out about new games. With a reach to consumers with a high interest in games, these entrepreneurs have become vital to companies looking for exposure for their games. They charge these companies up to $15,000 for a single post. And they create three to five posts per week. You do the math.

Whatever you’re into, other people are into it too. Your interest may seem niche, but the internet allows you to connect with enough people to turn a niche interest into a large business. These two entrepreneurs have built audiences who have the same interests they do and, in turn, created businesses around charging companies who want to access and market to those “niche” audiences.
