How a 21-Year-Old Coach Built One of Australia's Biggest Gymnastics Businesses From Scratch

He started coaching at 14. Became head coach at 17. And by 21, he'd taken over the whole business, with a payment plan and a dream to prove gymnastics coaching was a real career. 30 years later, Delta Gymnastics is one of Australia's largest privately owned gymnastics clubs, with 150 staff, 6+ million hours of coaching delivered, and a net promoter score of 75, putting it ahead of most global brands. In this episode Andrew Murphy sits down with Delta co-founder John Mitchell to unpack exactly how he built it. You'll learn: — Why John says "our systems make us good, our people make us great" and what that actually looks like in practice — The E-Myth principle that changed how Delta scaled to multiple venues — How Delta built a curriculum system that eliminated reliance on individual coaches — Why they use NPS continuously (not annually) and how it went from 22 to 75 — Blue Ocean Strategy in real life, and why John refuses to copy competitors even when clients suggest it — The "four types of customers" model Delta uses to reduce churn from the national average of 10.3% down to 3.8% — What Jim Collins' "First Who, Then What" actually means when you're a founder of 30+ years — The AI warning every small business owner needs to hear right now 00:00 Intro 01:30 Why gymnastics?
