What began as a part-time side project; evenings, weekends and two 3D printers in a rented room has grown into a profitable, globally recognised business serving life sciences startups, research labs and multinational pharma companies.  But the part that makes Paul’s story compelling isn’t the technology.  It’s the honesty:  He never wanted to be a founder.  He never set out to run a business.  And yet here he is, leading a team, travelling the world for client meetings, navigating cash flow, BD, branding, and hiring… all while staying open, self-aware and disarmingly human about the whole thing.  In this episode of Why Design , Paul joins host Chris Whyte to unpack the journey: the technical foundations, the unexpected turns, the small risks, the networking habits, the content strategy, the international expansion, and what it really means to grow a niche hardware business without investment.  Don’t just listen.
