    From Professional Rugby To Building A €100m+ Business | Shane Leahy, Oxygen8

    Shane Leahy explains why rapid growth can become one of a business's biggest challenges, why great leaders build teams around their own weaknesses, and how the lessons he learned building Oxygen8 into a €100m+ global technology group are now helping him scale humanitarian aid in some of the world's most dangerous conflict zones. Shane Leahy joins Business Builders to share his journey from professional rugby into telecoms and entrepreneurship, eventually helping grow Oxygen8 from a €30 million business into a global technology group generating more than €100 million in turnover, with operations spanning Africa, the Middle East, Southeast Asia, Australia, the US and beyond. Shane reflects on the leadership lessons he carried from professional sport into business, why different people require completely different styles of management, and how recognising his own weaknesses helped him build stronger teams around him. He also discusses the challenges created by rapid international growth, a fraud of more than $10 million that forced the group to restructure, the importance of learning from failure, and why putting the right management structures in place became essential as Oxygen8 scaled. The conversation also explores Shane's decision to step back from the day-to-day running of his businesses and establish One for Humanity. Using the same proof-of-concept and scaling principles he learned in business, Shane and his team have helped establish 19 hospital units along the front lines in Ukraine and deliver more than $200 million worth of medicine, while also supporting humanitarian projects in Gaza and elsewhere. This is a conversation about entrepreneurship, leadership, professional sport, scaling, international business, failure, resilience, team building, self-awareness, humanitarian aid, purpose, Ukraine, Gaza, technology, organisational structure, founder mindset, and using business experience to make an impact far beyond business.

    The Hidden Problem Facing Women in Leadership | Hannah Wrixon, KELLA

    🔔🔔 Hannah Wrixon explains why the most successful women are often the least supported; and why she’s building a global network to change that 🔔🔔 Hannah Wrixon joins Business Builders to share the story behind Keller and why she believes one of the biggest challenges facing women in leadership is something few people talk about. After building and exiting multiple businesses, Hannah noticed a surprising pattern. While countless initiatives exist to support startups and emerging leaders, many of the women who had already “made it” were quietly carrying enormous responsibilities with very little support themselves. The executives and founders mentoring everyone else often had nobody to turn to when they faced their own challenges. That insight led Hannah to launch KELLA, a private global community for senior women leaders and entrepreneurs designed around peer-to-peer support, leadership development, and meaningful connections. Alongside the story of Keller, Hannah reflects on building and selling Get the Shifts, navigating Covid, understanding her own strengths as an entrepreneur, and why ambition and personal fulfilment are not always the same thing. She also shares her experiences as a woman entering heavily male-dominated industries in the 1990s, the importance of risk-taking, and why she proudly describes herself as “unapologetically ambitious”. This is a conversation about entrepreneurship, leadership, ambition, identity, and what success really means. “That’s all wonderful. But who’s mentoring you? Silence. Full stop.”   🎧 In this episode, you’ll learn: • Why the most successful women are often the least supported  • The story behind founding Keller and its mission to support women leaders  • Why Hannah’s first attempt at building Keller went badly wrong  • The costly mistake she made with Builder.ai  • How she built and exited Get the Shifts  • Why she sold the business after Covid  • The challenges of balancing ambition with family life  • Why knowing your strengths matters as a founder  • How a conversation with her son changed how she thinks about identity  • Why she believes women should be unapologetically ambitious  • What success means to her today  • How Keller plans to become a global network for women leaders ⏱️ Timestamps 00:00 - Cold open  01:03 - Introducing Hannah Wrixon and Keller  02:55 - Why she founded Keller  05:18 - “Who’s mentoring you?”  05:47 - The mistakes she made building Keller  08:38 - Why the original tech platform failed  10:27 - Losing money on Builder.ai  12:08 - How Keller works today  18:47 - Expansion into the UK and global ambitions  22:45 - The story behind Get the Shifts  27:34 - The reality of entrepreneurship and cash flow  29:50 - The bank almost stopped payroll  32:21 - Covid and reinventing the business  36:21 - Why she sold the company  37:37 - “You’re my hardest-working, poorest friend”  38:48 - Why entrepreneurs don’t work normally  39:14 - Work addiction and identity  41:07 - Her relationship with her son Callum  43:02 - Why selling the company felt disappointing  46:22 - Finding purpose through Keller  50:34 - Being told there were no jobs for women in engineering  55:03 - The challenges women leaders still face  58:19 - Becoming an accidental entrepreneur  59:37 - Why she isn’t afraid of failure  01:01:10 - Being “unapologetically ambitious”  01:02:47 - What she wants written on her gravestone Topics covered: Women in business, women in leadership, entrepreneurship, startups, founder mindset, leadership, ambition, purpose, identity, work-life balance, business exits, scaling companies, peer networks, executive leadership, female founders, mentoring, gender equality, confidence, family, personal development, business growth, Keller, Get the Shifts, leadership development, founder psychology.
