In this episode of HealthTech with Purpose, we welcome Koen Kas, a healthcare futurist, author, keynote speaker, and founder & CEO of Health Scouts. Koen shares his vision of a healthcare system where digital technology and biological data converge to create personalized health experiences. He explains how digital twins, genomics, wearables, and artificial intelligence are reshaping preventive care, patient engagement, and cost management in healthcare.

Koen emphasizes shifting from reactive sick care to proactive health maintenance, where citizens are supported by digital tools and biological insights to live healthier, longer lives. He also details his work on Health Scouts’ certified health app database and the methodology for building impactful digital health solutions.

This forward-looking discussion offers valuable lessons for providers, payors, startups, and innovators striving to integrate AI in healthcare, improve clinical operations, and embrace digital health transformation.

Ayush Jain:
Hello everyone, welcome to another episode of HealthTech with Purpose. Today we have Koen Kas joining us — a healthcare futurist, author, inspiring international keynote speaker, and the founder & CEO of Health Scouts.

Ayush Jain:
Koen, welcome to the show! Could you start with a quick introduction?

Koen Kas:
People call me a healthcare futurist, but I can’t predict the future. What I do is apply Delight Thinking — building experiences close to magic but real, helping people adapt to change. Healthcare resists change; innovation takes seven years on average to land. Technology alone doesn’t change the world — experiences do.

I trained as a biomedical scientist and worked with cancer patients, developing drugs for childhood brain cancer. My perspective shifted when I studied China’s ancient healthcare model, where doctors were paid only while villagers stayed healthy. That inspired my dream: a digital “Chinese doctor,” a digital twin always with us to keep us healthy.

Ayush Jain:
That’s a powerful vision. You’ve said: “The digital healthcare revolution was only the beginning — the biological revolution, AI, and digital twins will make past practices as archaic as the Middle Ages.” Can you expand?

Koen Kas:
Digital health was late but useful. The biological revolution — genomics, microbiome, proteomics — will be transformative. Sequencing a genome once cost $3B; today, it’s under $600 in three hours. Knowing predispositions (like blindness risk in my case) gives superpowers.

AI will become “anticipation intelligence.” It interprets massive biological datasets, helping us act early. Together, digital and biological data will build digital twins — personalized avatars predicting risks and guiding lifestyle choices.

Ayush Jain:
Where are we today on that journey?

Koen Kas:
We’re at 2 or 3 out of 100. Few people have access to their genome. But when people see possibilities, behavior changes. For example, a pill-camera instead of colonoscopy increases acceptance of screening. Or textile sensors detecting breast tumors early. Tech changes perception — bridging predisposition and action.

Ayush Jain:
And what about costs?

Koen Kas:
If we stick to sick care, costs will explode. Predictive tools are cheaper. A video selfie could predict diabetes from facial blood flow. Wearables detect habits and nudge healthier choices. Some countries reimburse preventive apps or pay citizens to live healthily. Prevention is not just ethical — it’s economical.

Ayush Jain:
What risks or barriers do you see?

Koen Kas:
Behavior change. Many doctors still rely on fax. In Germany, digital health apps are reimbursed, but only 2% of doctors prescribed them initially due to awareness and effort.
We must avoid siloed data. Platforms like the European Health Data Space and Tim Berners-Lee’s Solid protocol let citizens control their health data. That builds trust while enabling innovation.

Ayush Jain:
Tell us about Health Scouts.

Koen Kas:
We built a global database of ~340 certified health apps. We classify them by regulation, clinical evidence, IP, partnerships, and adoption. From this, we distilled five rules:

Think marketing first, not just technology.

Develop bottom-up with user involvement.

Design for usability — apps must fit into daily life.

Avoid silos — ensure data can connect.

Plan for integration into real care systems and decision-makers.

This helps startups avoid costly mistakes and build impactful solutions.

Ayush Jain:
That’s fantastic, Koen. Thank you for sharing such visionary insights.

Koen Kas:
Thank you. My mission is to help create a world where we live healthy, purposeful lives as long as possible — and where technology unlocks our full potential.
