HealthTech Hour

The NHS needs thousands more GPs - but what if the solution isn't training more doctors, but reconnecting qualified clinicians already outside the workforce?
In this episode of Health Tech Hour, Julian shares how a personal diagnosis of a bicuspid aortic valve sparked his journey into healthcare and why he believes preventative care should be far more accessible.
We explore:
why the NHS workforce crisis continues to worsen, why thousands of GPs are leaving the profession, how remote UK-qualified doctors can support primary care, the future of global healthcare workforces, why AI won't replace doctors anytime soon, the challenges of building healthtech companies in the UK, the role of prevention in reducing long-term healthcare costs, what the NHS 10-Year Plan means for healthcare innovation
Julian also explains how Asterix Health is helping GP practices manage complex clinical workloads, reduce administrative burden, and improve patient care by reconnecting experienced doctors with the healthcare system.
Whether you're a healthcare professional, founder, investor, policymaker, or simply interested in the future of healthcare, this conversation offers a fascinating look at one of the biggest challenges facing health systems today.

This week on HealthTech Hour, Steve sits down with Demi Radeva, CEO and co-founder of Across, who is helping UK health tech founders enter and succeed in the United States.
With nearly 20 years of experience spanning the world's largest US payer, the London School of Economics, and a teaching role at the University of Minnesota, Demi brings a rare dual perspective - she's lived inside both health systems, studied how they finance themselves, and built and co-founded multiple digital health ventures of her own.
Demi is particularly passionate about helping founders follow the money - understanding reimbursement, structuring ROI, and accessing the right buyers across the 1,100 decision-making bodies that shape US healthcare. We get into what that looks like in practice - why UK health tech consistently brings stronger evidence to the table, how to access programmatic spend when no billing code exists, and why making your customer money beats saving them money every time.
Outside of work, Demi is shaped by her own immigration journey from Bulgaria to the US, an experience that informs how she thinks about culture, incentives, and what it actually takes to move between two very different systems.
A sharp, practical conversation with one of the leading voices helping UK health tech founders take their first serious step into the American market.

This week on HealthTech Hour, Steve sits down with Sam Fay, CEO of SISU Health, who is leading the mission to make preventative health more accessible across the UK.
With 25 years of experience in strategic transformation and senior leadership, Sam has a strong track record of scaling organisations and delivering measurable impact - and she brings that operator's lens to one of the biggest challenges in healthcare today: shifting the system from treating illness to preventing it.
Sam is particularly passionate about using innovation and data to tackle health inequalities and improve outcomes at scale, and we get into what that looks like in practice - what's actually working, where the system gets stuck, and how SISU is building for reach rather than just reach for those who already engage with healthcare.
Outside of work, Sam is a keen outdoor adventurer - long walks with her Ridgeback, skiing, and coastal escapes when the diary allows.
A practical, grounded conversation with one of the leaders putting preventative health within reach of the people who need it most.

Rachel Murphy launched the NHS App and sold multiple businesses. Now she helps other founders do the same.
In this episode of HealthTech Hour, we sit down with Rachel Murphy — founder of The Grafter and one of the UK's most trusted operators when it comes to building real business value. Rachel has grown, scaled and sold multiple companies, including the eight-figure exit of her second business, Difrent. She also led the launch of the NHS App, now with over 30 million downloads and one of the UK's most impactful digital programmes.
At the start of 2026, Rachel was recognised on the Ideas Fest New Year Honours List, reflecting not just what she's built, but how she shows up for founders and leaders across the UK.
Through The Grafter, Rachel works alongside ambitious business owners who want to build something that stands up commercially, strategically and emotionally — helping founders create clarity, drive sustainable revenue, and build long-term value, whether they're scaling, raising, or preparing for their next chapter.
Known for her calm authority, straight talking, and ability to sit with complexity when it matters most, Rachel is the person founders trust when the stakes are high — because she's been there, she's done it, and she doesn't flinch.

This week, HealthTech Hour comes to you live from Digital Health Rewired at the NEC - one of the UK's biggest gatherings of the people building, leading and shaping digital health.
Steve is joined at the event by three special guests:
Alex Lawrence - Fellow at The Health Foundation, bringing a sharp policy and research lens to the conversations happening across the show floor.
Hassan Chaudhury - one of digital health's best-known advisors and connectors, with a knack for cutting through hype and spotting what actually moves the needle.
Hayley Grafton - an accomplished digital nurse leader, representing the clinical voice that so often gets left out of the tech conversation.
Together, they unpack what's really happening in UK digital health right now: the ideas getting traction at Rewired, the gaps between policy and frontline reality, and where the next wave of impact is most likely to come from.
A live, on-the-ground episode you don't want to miss.
