Description

In this episode, Jon and Steve are joined by three North East founders who’ve each taken very different paths to building a business:


💻 Mark Renney – Managing Director, Wubbleyou

🧠 Billy Webber – CEO, XR Therapeutics

⚙️ Jarek Rosinski – Founder, Transmission Dynamics


Together, they share candid stories about the highs, lows, and lessons of entrepreneurship – from turning university spinouts into thriving companies, to weathering setbacks and learning the value of resilience along the way.


We discuss:

• The defining moments that sparked their ventures

• Why resilience is more than just a buzzword

• Surviving setbacks and using them as fuel

• Balancing vision with day-to-day reality

• The advice they’d give their younger founder selves


This episode is an honest reminder that behind every business is a story of risk, resilience, and relentless determination.
