Mike Mayer: Turning a Simple Problem into a Thriving Business

From Frustration to Innovation

Mike Mayer, the co-founder and co-CEO of Windmill, didn’t set out to change the air care industry. He just wanted to help his brother install a window AC without the headache. That simple struggle sparked an idea—what if air conditioners were smarter, sleeker, and easier to use? Fast forward, and Windmill is now shaking up the air quality game with stylish, high-tech solutions.

How Mike Mayer Built Windmill

The idea wasn’t just about fixing one frustrating problem—it was about rethinking the entire experience. Mayer teamed up with co-founder Ryan, who had deep HVAC expertise, and they got to work. They knew people didn’t just need cooling; they needed efficiency, simplicity, and clean air. So, they designed a product that did it all.

Facing the Highs and Lows of Entrepreneurship

Building Windmill wasn’t all smooth sailing. Mayer had to learn one of the hardest lessons—separating himself from the business. Early on, every setback felt personal. A bad review? Crushing. Supply chain issues? Devastating. But he figured out how to stay passionate without letting the rollercoaster of wins and losses define him. That mindset shift made him a better leader.

Mike Mayer’s Advice for Aspiring Entrepreneurs

Mayer’s biggest tip? Don’t wait for the “perfect” time—because it doesn’t exist. Start with what you have, test your idea, and improve as you go. He also believes funding isn’t always necessary. Before chasing investors, he suggests asking: Can I build this step by step? Can I test demand first? Sometimes, scrappy marketing and organic word-of-mouth are all you need to get started.

The Secret to a Great Pitch

When it comes to pitching, Mayer keeps it simple:

Tell a great story. A strong narrative makes your pitch memorable.

Be yourself. Investors bet on people as much as ideas.

Know your numbers. Be ready to explain costs, profits, and market size.

The Best Advice He Ever Got

Mayer lives by Theodore Roosevelt’s Man in the Arena speech. It’s a reminder that critics don’t matter—only the people bold enough to take risks do. Whether you’re launching a startup or just starting to dream, his advice is clear: take the leap, learn fast, and keep going.
