Dyslexia, Deals & Devastation: Jez Williman on the Highs and Lows of Building Physical Products

It's only a Prototype

In this episode, we sit down with Jez Williman, a British entrepreneur whose journey has seen him build a business from $3 million to over $100 million in sales across 120 countries and then lose a second venture after years of development and personal investment.

Jez shares a candid, unfiltered story of the highs and lows of product entrepreneurship: from building an iconic (if invisible) product seen in airports and films everywhere, to the brutal lessons of raising capital, dealing with lawyers, and losing control to an investor. This one is packed with wisdom for founders who’ve ever put everything on the line.

In This Episode, You’ll Learn:

• How Jez scaled a niche product into a global industry
• What dyslexia taught him about resilience, learning, and creative problem solving
• The harsh realities of hardware development, investment, and prototyping
• Why big design firms aren’t always the right answer and what to do instead
• The devastating consequences of trusting the wrong lawyer
• How to validate your product cheaply (before spending big)
• The mindset and sacrifices needed to succeed across business and elite sport
• Why Jez is starting again with a new venture in smart crowd control systems
