How Duke Baxter built a $3M+ youth baseball coaching business

Duke Baxter

Dominate The Diamond

Duke Baxter is the founder of Dominate The Diamond, an online training business that helps youth baseball and softball coaches run better practices, teach fundamentals, and build player confidence. Since 2017, his online programs have generated over $3 million in revenue.

Duke didn’t overcomplicate things. He took his real-life coaching experience and packaged it into practical online courses and memberships. His approach focuses on simple, ready-to-use drills and plans - exactly what busy coaches need - rather than theory or fluff.

His growth comes from posting free drill videos and short coaching tips on social media, which reach thousands of coaches. Those free lessons lead people to his website, where they can download practice plans, join his email list, or sign up for paid programs. Word-of-mouth from happy coaches keeps the growth rolling.

Don’t guess - test it. Create a one-page offer describing your idea, who it’s for, and what it helps them achieve. Share it with 20–30 people in your target audience. If a few ask, “How can I buy this?” - you’ve got proof of concept.

Too many people build in silence and hope it works. Real validation comes from real people saying “yes.” Keep testing small before you build big.

When you’re stuck on what business to start, make a list of 5 problems people ask you about most often. The one that keeps coming up is your opportunity. Problems equal profit.
