Owen Jennings, the head of product at Block Inc(NYSE:XYZ) and a key person around the executive table of what is now by market cap, one of the largest 500 companies in the world.Block (formerly known as Square) is really several powerful ecosystems under one roof: Square serving millions of merchants; Cash App, the consumer super app that's become the financial home for tens of millions of people; and of course, Australian founded Afterpay, the global buy-now-pay -later platform that connects these two bringing shoppers and sellers together. Owen is one of the rare executives that has truly grown up inside acompany over the past 13 years. Owen has worn just about every hat from early roles in ops to becoming the COO of Cash app where he helps scale it from a scrappy side project into a FinTech powerhouse that now generates c$6 billion in annual gross profit.Today Owen leads product across all of Block. He's widely credited for the new sense of product velocity inside the company and the ability to ship faster, to experiment at scale, and to embed AI as a multiplier in everything they do. Most importantly, this is a story about scaling culture. Block’s managed something that very few founder-led companies of its size and scale can achieve re-engineering that start up DNA inside a scaled business. Owen has been atthe heart of this cultural reset - hands-on close, to customers and unafraid to tinker with the new ideas himself.

From a kitchen table in Liverpool, England, to the dressing rooms of some of the world's biggest sports teams, Castore is one of the fastest growing premium sportswear brands on the planet. Founded in 2015 by brothers Tom and Phil Beahon, both former professional athletes. Castore was built on grit, obsession and a bit of a chip on the shoulder. With no fashion experience, no contacts, no outside investment – the brothers remortgaged, their parents' home, lived off just a thousand pounds a month and packed boxes late into the night. Their mission - to build a British challenger to the global sportsweargiants Nike and Adidas - a brand that blends high athletic performance gear with the sophistication of luxury fashion. Fast forward almost a decade and Castore is rewriting the rules of the industry. They've developed proprietary fabrics, run a fully integrated design to distribution platform, and perhaps most disruptively, ripped up the old team apparel playbook, forging deep digital first partnerships with elite teams in cricket, rugby, football, and Formula One.

The scale is bigger. But what about the founder?This episode is about going deep on that next chapter—what’s changed, what hasn’t, and what Steven’s learned along the way.

Silvija Martincevic, the Croatian born, San Francisco based CEO of Australian founded Unicorn Deputy.Silvija's executive career has been immense in the world of fast-growing technology, as the COO of Group On, and then the chief commercial officer of Affirm, that scaled annual revenue through the billion-dollar ceiling and beyond IPO. Silvija grew up in Croatia and while she didn't learn English until she was 18, she's an incredibly lucid storyteller. We traversed some key scaling challenges from moving Deputy from a point solution to a full workforce management platform trying to move from the fickle SMB market towards solving larger and more complex problems for mid-market customers. All of this is wrapped up in a big global push to continue the growth trajectory that now has reported revenue well over a hundred million dollars a year. While Silvija is known in the industry as an incredible executor, as an operator, it's her leadership skills that have been front and center in Deputy’s post Covid transformation, despite not being the founder, her ownership mentality is the cornerstone of her values-based leadership principles, which come clearly through as accountability, trust, and empathy. Her insights into scaling culture as a non-founding CEO were a real highlight of the conversation.

Very rarely do you get to tell the story of a wildly successful entrepreneur that is largely unknown beyond the immediate circle of influence. Today on Scaling Up, Greg Boorer, the CEO and Founder of CDC, formally Canberra Data Centres, which is in some rarefied air among companies globally, having compounded earnings at over 30% for the last 15 years. It's now valued well in excess of $10 billion and is at the centre of the beating heart of Australia's critical infrastructure. All this, and it still has a massive growth runway ahead of it. Greg's story in many ways is the CDC story from an aspiring cyclist and reluctant it graduate. Greg has become the face and often lead salesperson of a business that has rewritten industry standards as it relates to innovation and security. In what is seen from the outside as a commoditised industry, CDC has thrived by listening to customer needs and adapting accordingly. This is a story of initial hustle and belief in an opportunity, but ultimately it's about resiliency and delivering on promises. Greg has undoubtedly built one of Australia's best businesses from the ground up, and to hear him speak about this scaling journey with the knowledge and passion that he does will undoubtedly be inspiring to all our listeners.
