Why You Can't Boil the Ocean When Building a Device: Interview with Vital Signals CEO Tom Moss

Blood pressure management requires a shift from cumbersome, inaccurate cuff-based devices to continuous, calibration-free monitoring solutions like the Signal Ring. Traditional methods often fail to account for fluctuating arterial environments, leading to data drift and unreliable results. Developing hardware for this space demands a focus on readily available, proven components to avoid the supply chain vulnerabilities that frequently plague early-stage startups. Rigorous clinical validation, such as a 792-subject study covering diverse demographics, is essential to ensure accuracy and overcome the limitations of small-scale, non-representative testing. Beyond technical hurdles, successful ventures rely on founders who possess deep curiosity and resilience, as the path to market involves navigating existential obstacles and persistent rejection. This mission-driven approach, combined with a focus on user experience and data-backed insights, enables a more personalized understanding of cardiovascular health and long-term arterial wellness.
