As consumer wearables track everything from our heartbeats to nightly sleep cycles, a new industry has emerged—one focused on making sense of this avalanche of personal health data. In an era when prevention is prized over cure, questions abound: How accurate is the data captured on our wrists and fingers? Can these metrics truly guide us to longer, healthier lives, or are we just generating noise? 

For Marco Benitez, a biomedical engineer and co-founder of the health data platform Rook, the challenge isn’t just about collecting the numbers but turning them into actionable insights—for both individuals and the broader healthcare world. As the medical establishment wrestles with integrating this torrent of information—and as users grapple with privacy and security—a revolution in health is quietly unfolding. 

Peter Bowes sat down with Benitez to discuss the promise and pitfalls of wearable data, the evolving relationship between Big Pharma and digital health, and what it will take to shift the system from sick care to prevention.
