Spiden

Liom, formerly known as Spiden, is a Swiss medtech company developing a non-invasive wearable platform for continuous biomarker monitoring, beginning with glucose. The company combines optical spectroscopy, sensor engineering, and machine learning to measure biomarkers without needle-based sampling or per-subject invasive calibration. Its lead product is a wrist-worn glucose monitoring device aimed at consumer health, metabolic monitoring, and potentially diabetes-related applications. Liom positions its technology as a broader biomarker platform that could later expand beyond glucose to lipids, proteins, ketones, hydration, and lactate. The company is private, based in Pfäffikon, Switzerland, and has also established a presence in San Francisco.
