Summary
What connects offshore engineering, inkjet printers, molecular diagnostics and a small workshop in a church in Newcastle? For Paul Marshall , it’s all part of the same journey: a lifelong fascination with how things work, and a belief that good engineering can solve meaningful problems. Paul is the co-founder of Rapid Fluidics , a UK consultancy and prototyping company specialising in microfluidic cartridges. 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.
