Faces of Digital Health

Digital health is no longer in its honeymoon phase.

The funding boom is over. AI hype is everywhere. Health systems are overwhelmed. And startups can no longer survive on compelling pitch decks alone.

In this episode of Faces of Digital Health, Tjaša Zajc speaks with Ruchi Dass, a former dental surgeon turned public health leader, policy contributor, investor, and advisor to startups scaling across the US, UK, India, Africa, and the Middle East.

Ruchi describes a fundamental change in go-to-market (GTM) strategy:


Workflow integration is non-negotiable (standalone apps struggle).


Reimbursement clarity is critical.


Regulatory strategy is part of GTM, not an afterthought.

In this episode of Faces of Digital Health, host Tjasa Zajc sits down with Bart de Witte for a candid conversation on what agent-based AI really means for healthcare.

Recorded during a car ride in Ljubljana, the discussion explores why healthcare needs an operating system for AI agents, the risks of agent autonomy, privacy-by-design through on-device AI, and why monolithic EHRs struggle with the next generation of clinical workflows.

Bart also shares his vision for open, decentralized AI ecosystems, certified clinical agents, and swarm intelligence and explains why Europe may be uniquely positioned to lead this shift.

A practical, forward-looking episode for anyone working at the intersection of healthcare, AI, and digital infrastructure.

As artificial intelligence rapidly enters healthcare, bold claims about replacing doctors dominate headlines. But on the clinical frontline, the reality is far more complex.

In this episode of Faces of Digital Health, oncologist Dr. Derrick Khor shares an unfiltered view from inside the NHS, unpacking what AI actually changes — and what it doesn’t.

Rather than framing AI as a threat, the conversation explores how it already supports clinicians and patients alike: simplifying complex medical information, helping patients understand their diagnoses, and accelerating access to evidence. Yet the biggest constraint isn’t technology — it’s data. Without reliable access to their own health records, patients and AI tools alike remain limited.

The discussion also tackles a growing contradiction in healthcare systems: simultaneous staff shortages and doctor unemployment. Training bottlenecks, hiring freezes, pay erosion, and misaligned workforce planning have created a situation where well-trained clinicians struggle to find roles, even as demand for care continues to rise.

Beyond workforce pressures, Dr. Khor explains why most health tech never makes it into daily clinical use. Solutions often fail not because they’re unsafe or ineffective, but because they don’t fit real workflows. If technology adds friction even a single unnecessary click — clinicians won’t adopt it.

Ambient documentation is becoming normal in clinics. But the most interesting “voice” capability may not be transcription at all.In the latest episode of Faces of Digital Health, Henry O'Connell (Canary Speech) explains why voice biomarkers stalled for decades: the field analyzed words, not the neurological signal behind speech production.Canary’s approach focuses on the “primary data layer”—how the central nervous system drives respiration, vocal cord vibration, and articulation in real conversational speech.

A few details that stood out:

⏱️ ~45 seconds of conversation can be enough for assessment

🎛️ 2,590 voice features analyzed every 10ms (millions of data points)

🎯 Reported accuracy: 98%+ for progressive neurological conditions (e.g., Parkinson’s/Huntington’s/Alzheimer’s), while behavioral health tends to be lower (often in the 80s)

🌍 Validation is repeated per language/culture—no “deploy and hope” model

🧭 Use cases go beyond diagnosis: screening in primary care, clinical trials outcome tracking, and even in-room aggression risk signals to help protect staff

One line that captures the idea: it’s about measuring what’s present in the moment—objective signals that complement clinical judgment.

The conversation explores the impact of robots on mental health and their role in healthcare. Anthropologist Tanja Ahlin and Faces of digital health host Tjasa Zajc discuss the fascination with robots, the ambiguous identity of robots, their use in elder care, the challenges of integrating robots, the global perspective on robots, and the misconceptions and realities of robots. The conversation explores the impact of technology on different generations, the role of individual choices in technology use. The speakers also talk about concerns about children and technology, the role of parents, and the impact of technology on human development and creativity. It also emphasizes the importance of optimism and flexibility in adapting to technology.
