Navigating the US Healthcare System for UK Founders with Demi Radeva, CEO of Across

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.

Tackling Health Inequalities with Data and Innovation with Sam Fay, CEO of SISU Health

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.

The National Joint Registry is the most impactful health data science project you've never heard of - why and how it's transformed healthcare in the UK

20 years ago, there was a scandal around dodgy hip replacements failing. The NHS had no national register for hip replacements - so Richard Armstrong and others set about building one and that is called the National Joint Registry. Scroll forward to today and it is the leading global database for implants and connecting to outcomes. The data is so comprehensive that Richard and his team are able to predict which implants will deliver the best outcomes and the best long-term ROI for any healthcare system. Richard Armstrong is Director of Registries and RWE at NEC Software Solutions and his passion is data science in health - and the impact of his passion is felt throughout the healthcare service, Richard has worked in healthcare informatics for the past decade, running national programmes associated with the collection and reporting of healthcare data. A key aspect of Richard’s work is designing and managing medical registries which analyse data on medical procedures, devices and outcomes. Richard has a pivotal role in advancing real-world evidence initiatives in healthcare, which can significantly impact treatment decisions and patient safety.

Why language barriers in the NHS hurt patients - and one woman's mission to solve this problem with Kavita Parmar, founder of Word360

The data is clear - language barriers hurt patients, in any healthcare setting. In some settings, for example acute, maternity and others, these barriers can lead to very serious situations. Kavita Palmer is a clinician by background and Co-Founder of Word360, a multilingual and translation support platform used across the NHS. Her mission is to solve this, at scale - and the problem is vast. Think about all the communication, written, verbal, paper, electronic, across all healthcare pathways. Last year in London alone, they provided 167 different languages to NHS clinicians and patients and have the ability to offer 450+. As Britain's demographics shift, this will become ever more important to solve efficiently.
