Ray Liu
Ray Liu is the CEO and co-founder of Vena Vitals, an Irvine, California medtech startup building a soft, skin-like sticker that tracks blood pressure continuously, beat by beat, without cuffs or invasive arterial lines. A National Science Foundation fellow turned operator, Liu spent two decades inside GE Healthcare, Siemens, and Vizient, and racked up two health-tech exits before reuniting with a former Berkeley labmate, UC Irvine professor Michelle Khine, and PhD scientist Josh Kim to turn a material-science breakthrough into a clinical product. Backed by Y Combinator, MedTech Innovator, and EvoNexus, Vena Vitals has tested its sensor on 600-plus patients in operating rooms and is targeting FDA clearance in 2026.
