It's only a Prototype

It's only a Prototype
Podcast Description
Bringing a physical product to market is never a straight line. It’s messy, unpredictable and full of costly mistakes. It’s only a Prototype is the podcast that tells the real stories behind product innovation. No hype. No polished PR spins. Just honest, hard-won insight from people who’ve lived it.
Hosted by Phil Staunton (Founder of D2M product design agency: https://www.design2market.co.uk/) who brings with him a wealth of industry experience and Tom Constable a seasoned podcast host and serial entrepreneur.
This show explores the unfiltered reality of designing, prototyping, manufacturing, and launching physical products.
Each episode features candid conversations with founders, product leads, engineers and innovation specialists who have faced down challenges in new product development (NPD). We learn what separates commercially successful products from costly flops, exploring real-world decisions, moments of uncertainty, and the lessons learned through failure.
This podcast is for you if you’re serious about turning good ideas into great products. Whether you’re:
- Leading innovation, product or R&D teams
- Founding and growing a product-based business
- Managing design and manufacturing processes
- Supporting product success through marketing, strategy or operations
…you’ll gain practical insight into the challenges that really matter.
We cover questions like:
- How do you balance innovation with commercial viability?
- How can you validate an idea before investing heavily?
- How do you manage stakeholder conflict, evolving product requirements or manufacturing risk?
- When do you push forward and when do you pivot or walk away?
From idea to shelf (and every stage in between), It’s only a Prototype is your behind-the-scenes guide to what it really takes to bring a physical product to life... and make it work.

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
