Spencer Dennis was an elite golfer whose playing career ended with spine surgery in his teens. He became a tour-level coach, running high-performance programs for juniors, college players, and pros. Managing parents, trainers, and recruiters through texts and email was chaos, so he built CoachNow to guide athletes between sessions.

CoachNow caught on quickly with busy coaches. Then a run of decisions—turning off revenue under "grow fast" advice, stacking convertibles and preferences, and accepting stock-for-stock deals—left Spencer with little to show for a product customers loved. This is a cautionary tale for any owner negotiating with "sophisticated" investors.
