Ever wonder why some startups follow every “right” rule and still fail, while others break every norm and dominate? Mike Maples (Floodgate, author of Pattern Breakers) reveals how true breakthrough startups aren’t built by checking boxes—they’re created by founders bold enough to reject consensus, ignore conventional wisdom, and rewrite the rules entirely. 

This episode explains why your biggest risk isn’t failure, it’s wasting years on the wrong idea. If you want to build something people are desperate for, not just mildly interested in, Mike’s insights will change how you think about startup success.

Why You Should Listen

• How to know if your startup idea is worth years of your life—or if it’s secretly wasting your time.
• Why “non-consensus and right” ideas create billion-dollar breakthroughs.
• How raising too much money too soon can sabotage product-market fit.
• The difference between playing by market rules and inventing your own.
• Why the best startup ideas polarize rather than please everyone.
