About

I work with founders and investors to turn early-stage healthcare technologies into fundable, validated medical and IVD products. With a background in design engineering and medical device leadership, I help translate complex ideas into clear product strategies, development roadmaps, and regulated device programmes – from concept through to validation, regulatory readiness, and commercialisation. A key focus of my work is building investable propositions: aligning technical, clinical, and commercial requirements early to support fundraising, reduce risk, and accelerate scale-up. My approach is structured, evidence-led, and collaborative, with a strong emphasis on early alignment and clear decision-making. I believe that successful device development is a result of leveraging the diverse strengths of a team and empowering each member to bring their unique perspective to the table. If you’re developing a medical, IVD, or healthcare innovation and need support turning it into a viable product and business, feel free to connect.
