From building the YKTR clothing brand out of nothing to nearly losing it all, former NRL player turned entrepreneur Isaac John has packed a lot of hard-won wisdom into his last 10 years in business.
In a recent episode of Let's Talk Business, Isaac opened up about ego, failure, culture and what actually builds a brand people trust.
One of his biggest lessons was that ‘success without self-awareness’ is not sustainable. When one of his businesses failed and his partners walked away, Isaac said he spent about 18 months blaming everyone but himself.
“Eventually I held up the mirror and thought, ‘there he is – there’s the guy who messed up’.”
Reflecting on the experience and being willing to take hard lessons from it has helped him recognise his own strengths and weaknesses as a business owner.
“One of the biggest lessons from that time: when people were trying to buy the brand or buy into it, I had too much ego. Because I’d built the brand up, I thought I needed to sit at the top of it. But running a business day-to-day isn’t my strength.”
Isaac is a great example of a business owner that has been prepared to have a crack and also take notice of learning points along the way – even if those lessons are uncomfortable – to build and improve his craft as a business person.
Here are the 10 biggest takeaways from our conversation:
1. Ignorance can be your greatest asset – at first
Isaac doesn't credit his early success to strategy or capital. He credits ignorance. "I just thought I was going to walk in and kill it," he says of starting YKTR. He didn't know how to do taxes, didn't understand how hard branding would be, and had no clothing-brand blueprint to follow. That naivety was terrifying, but it was also what got him moving – most people who fully understood how hard it would be might never have started at all.
Takeaway: Don't wait until you feel ready. Some of the best business decisions are made before you know enough to talk yourself out of them.
2. You can't do everything – niche down or get lost in the noise
Isaac learned this lesson twice: once early, when YKTR tried to "do everything" and expand into activewear, streetwear and more, and again more recently, as he rebuilds around focus rather than breadth. "There's so many clothing brands now, you have to niche all the way down," he says, comparing it to a restaurant with a one-page menu versus one with 50 pages of average food.
Takeaway: Trying to please everyone usually means pleasing no one. A tightly targeted offer beats a broad, diluted one.
3. Give away almost everything – trust is the real currency
Isaac built a reputation for transparency by documenting his entire journey publicly, from factory visits in China to the mistakes along the way. His advice on content and sales is blunt: "You could give away 95% of everything that you know. Most people wouldn't be able to do it." Rather than eroding his business, that generosity built the trust that made people want to buy from – or work with – him.
Takeaway: Being open about your process doesn't dilute your value. It builds the credibility that eventually converts into sales.
4. A brand needs a divide, not universal appeal
Talking about the streetwear label Geedup, Isaac highlights a strategy many businesses avoid: deliberately creating an "us versus them" identity. "They create such a big divide – it's like you're either with them or you're not," he explains. That polarisation, aimed at a specific 2–5% of the market, is what drives perceived value and urgency, not broad likeability.
Takeaway: A brand that stands for something will always outperform a brand that tries not to offend anyone.
5. Personal brand won't replace a good business – but it will accelerate it
Isaac is clear-eyed about the limits of personal branding: it's not a requirement for success, but it compresses the timeline. "All personal brand does is create an energy around you that attracts opportunities a lot quicker," he says – like walking on an airport travelator instead of the floor. Paired with a strong, non-owner-dependent business, it becomes what James calls "turbocharged".
Takeaway: Build a business that works without you, then use your personal brand to accelerate its growth – not to prop it up.
6. Watch out for flattery – it's a warning sign, not a compliment
One of Isaac's sharpest insights on people management: flattery is a red flag. "People that only speak from a place of flattery, their intentions are never pure. They're there with you for a reason," he says. He learned to treat excessive praise as a signal to be more discerning, not less.
Takeaway: The people worth keeping close are the ones willing to challenge you, not just applaud you.
7. Success without self-awareness leads to collapse
Isaac's most candid moment in the interview is about the period when his media company failed, his team walked away without contracts, and he found himself in significant debt. Looking back, he says the real turning point was learning to stop blaming others: "I was broke for a year and a half... it was never my fault.” And then suddenly he got the mirror out. He also admits his ego – tied to being seen as smart and successful – made him defensive to feedback and reluctant to hand over control, even when the business needed someone else running day-to-day operations.
Takeaway: The fastest way to grow is to stop protecting your ego and start being honest about your own role in what's gone wrong.
8. Sport teaches you to compete – business requires you to collaborate
Isaac spent years treating other entrepreneurs, especially other former footy players, as competitors, because that's how sport had trained him to think. He eventually realised business doesn't work that way: "Within business, everyone can win... if you're in the right mindset of sharing." Helping someone else succeed doesn't cost you your own success.
Takeaway: A scarcity mindset built for the football field doesn't translate to business. Collaboration and generosity compound; hoarding information doesn't.
9. What you do off the field (or outside the business) matters just as much
Isaac describes a period where his identity, health and happiness were entirely tied to sales numbers – when revenue was down, he stopped training, stopped looking after himself and worked 16-hour days chasing solutions that never came. The breakthrough moments, he notes, actually happened away from his desk – running, or in the water. "Sometimes when you're in the hornet's nest, it's hard to see," he says.
Takeaway: Your business isn't your identity. Protecting your health, relationships and time away from work isn't a distraction from success – it's part of what makes it sustainable.
10. Know your future buyer before you need one
Toward the end of the conversation, James shared the story of a client who built a £100 million online sporting goods business and always understood, from day one, the kind of company that might eventually want to acquire it – even without a fixed exit date. Isaac takes the same lesson into his current plans for a "house of brands", thinking not just about growth, but about which private equity firms or larger apparel players might be a fit down the track.
Takeaway: You don't have to be planning an exit to benefit from thinking like a future seller. Understanding your eventual buyer shapes smarter decisions today.
The bigger picture
What ties all 10 lessons together is a theme Isaac returns to again and again: business success isn't just about strategy – it's about self-awareness.
From niching down to managing ego, from building trust to knowing when to step back, the biggest gains in his career came not from working harder, but from seeing himself and his brand more clearly.
